The Gate: Clearance First, Integration Second
RTX's current hiring push spans 179 open roles across Collins Aerospace, Pratt & Whitney, and Raytheon, and the company's own careers portal reveals a screening hierarchy that starts with active government clearances and moves quickly to demonstrated systems-integration experience on defense programs. As of mid-July, ClearanceJobs listed 1,434 total RTX openings; 1,209 required at least a Secret clearance, with additional postings specifying TS/SCI or TS/SCI with polygraph. The same listings carry a recurring line: "Will sponsor a clearance," but only for candidates who already clear the initial technical screen.
That screen centers on systems engineering titles that appear repeatedly across the three business units: Principal Systems Engineer – Air Dominance Production, Senior Systems Engineer – Analysis and Test Execution, Systems Engineer II – Radar Systems, Systems Security Engineer II. Each role description emphasizes cross-domain integration: tying radar hardware to fire-control software, linking propulsion test data to digital twin models, embedding cyber resilience into avionics architectures. The language mirrors Raytheon's public careers statement that its work spans "air, land, sea, space" and "integrated air & missile defense": mission areas where a component-level specialist stalls unless they've managed interfaces across subsystems.
The clearance requirement isn't a preference; it's a scheduling constraint. A Secret clearance takes months to adjudicate. TS/SCI takes longer. RTX's willingness to sponsor applies only after a candidate proves they can contribute to a funded program immediately upon clearance grant. That reality reshapes the applicant pool before a recruiter ever opens a file. Candidates without an active ticket or recent defense-program exposure face a delay most hiring managers cannot absorb.
The three business units apply this filter differently. Collins Aerospace roles lean toward avionics integration and flight-deck systems. Pratt & Whitney postings stress propulsion test and digital-engine-thread experience. Raytheon listings dominate the missile-defense and radar-integration space. But all three share the same gate: active clearance plus a resume that shows you've shipped a system through a defense program lifecycle, not just a lab demo.
That gate is where the 179-role surge meets the talent market's friction.
Rewriting the Resume: Program Names Over Keywords
The Workday parser that gates every RTX application has turned resume writing into a precision exercise. ResumeAdapter's May 2026 review of more than 600 postings across the Raytheon, Pratt & Whitney, and Collins career sites found that the single highest-scoring signal pair is an active clearance — Secret, Top Secret, or TS/SCI — paired with a named program such as Patriot, LTAMDS, F135, GTF, or Pro Line Fusion. Resumes that place both in the summary header land in the top quartile before the parser ever reads a skill or a date. Candidates who miss that pairing disappear.
Clearance placement has become non-negotiable. The ResumeFast guide notes that clearances take six to eighteen months to process, so hiring managers will take a cleared candidate with seventy percent of the required skills over an uncleared candidate with one hundred percent. Applicants now put clearance in a dedicated section directly below contact information, using the exact terminology the requisition calls for: "Active TS/SCI" or "Active Secret." No euphemisms.
Vocabulary has shifted from generic to program-specific. Radar engineers who once wrote "phased-array radar experience" now write "AESA T/R module design for the LTAMDS radar program at Raytheon Andover MA, using GaN MMIC technology to improve detection range by eighteen percent while meeting AS9100D and ITAR export control requirements." Pratt propulsion engineers who led high-pressure compressor aero design for the PW1100G GTF now cite FAR Part 33 certification gates, bird-ingestion testing, and a four-month reduction in time to type certificate. Collins avionics applicants reference DO-178C, DO-254, ARP4754A, and Form 8130-3 by name, not "avionics software standards."
Quantified outcomes have replaced vague claims. The cybersecurity examples in the ResumeFast guide show the pattern: "Monitored fifteen thousand endpoints using CrowdStrike and Splunk, triaging two hundred-plus alerts weekly and reducing mean time to detection from four-point-two hours to forty-seven minutes." Another: "Led RMF authorization for a forty-five-million-dollar defense communications program, shepherding three systems through ATO in six months, forty percent faster than organizational average." Each bullet pairs a program name, a standard or tool, and a metric.
Compliance language now sits beside technical language. Resumes include AS9100D, ITAR, EAR, CMMC, NIST 800-171, DFARS, and authority-to-operate processes in the same skills column as AESA, FADEC, ARINC 664, and HWIL. The ResumeAdapter guide warns against keyword stuffing; instead, applicants integrate terms into four buckets: summary, experience bullets grouped by program, a skills section organized by business unit, and a certifications line that lists PE, Six Sigma, AS9100D Lead Auditor, or DO-178C qualification.
Veterans are translating military occupational specialties into the same framework. RTX's dedicated military hiring programs mean a former fire-control technician now writes "SPY-6 radar maintenance and calibration aboard DDG-51 class destroyers, supporting Aegis baseline 9 integration under NAVSEA standard work packages," naming the platform, the system, the program, and the governing standard.
The CAR method — Challenge, Action, Result — structures every bullet. Applicants read the legal entity in the job posting footer to confirm whether they are targeting Pratt (East Hartford CT), Collins (Cedar Rapids IA), or Raytheon (Tewksbury MA, Andover MA, Tucson AZ), then pull the corresponding vocabulary list. They do not over-classify; everything on the page remains unclassified, describing scope, frameworks, and outcomes without sensitive details.
The result is a resume that speaks the parser's language and the hiring manager's language simultaneously. The candidate who once submitted a solid aerospace resume now submits a targeted RTX resume, and the difference is the interview.
The Funnel: Thousands Apply, Dozens Qualify
RTX's 179 advertised openings sit inside a much larger funnel. LinkedIn lists more than 1,000 open roles across the company as of July 2026, while Glassdoor surfaces 179 postings with salary bands and employee reviews. The gap between those two counts hints at how many requisitions never reach public boards, or how fast they're pulled once a referral pipeline delivers. Either way, the volume of applicants per role has exploded. Hiring managers across the industry report an order-of-magnitude jump: positions that once drew 30 résumés now field 300, and some specialized engineering reqs attract thousands. In a July 2026 video analysis, developer Trisha Gee put it bluntly: "I know some roles that are getting thousands, if not tens of thousands of applicants."
"There are fewer jobs than before," Gee noted, and candidates now need to apply to "way more jobs in 2026" to land a single interview. For RTX, which employs roughly 185,000 to 195,000 people globally across its three units, the math is unforgiving. A single systems-integration role requiring an active TS/SCI clearance and model-based systems engineering (MBSE) experience might pull hundreds of applications. Of those, perhaps dozens hold the clearance. Of those, a fraction have the specific MBSE toolchain the program office uses. The rest are noise, and the noise is growing.
Traditional screening cannot absorb it. Smaller firms without dedicated recruiting teams are already drowning; RTX has the infrastructure, but its recruiters face the same signal-to-noise collapse. The response has been a rapid shift to AI-assisted screening. Multiple sources confirm companies are "turning to AI to help them do the screening," and the algorithms are tuned for exact keyword matches against the job description. That creates a perverse incentive: the applications that score highest are the ones generated by large language models to mirror the posting, while human résumés — inevitably imperfect, phrased differently, shaped by real project variation — fall below the threshold. Gee described the outcome: "The only applications that are going to perfectly fit a job description will have been written by robots, not by real people."
The arms race cuts both ways. Candidates use Claude or ChatGPT to tailor every bullet; recruiters run Codex or proprietary models to filter. When the models disagree ("Codex doesn't like content created by Claude"), qualified humans get rejected by proxy. The same analysis reports candidates with inside referrals still striking out on official portals: "I have had zero success applying for jobs via LinkedIn or a company's official process, even when I also had an inside referral." Every interview Gee secured came from direct relationships or public technical work (videos, open-source contributions, conference talks) that bypassed the automated gate entirely.
Time-to-fill stretches as a result. Industry benchmarks show aerospace and defense roles already averaging 60–90 days from requisition to start date; the current volume spike and AI false-negative rate push that higher. Hiring managers, wary of "deep fake AI applicants" potentially controlled by adversarial actors, have added verification steps. Each layer filters more humans. "I'm really concerned… that it's much more likely to make it more difficult for some really great candidates to make it through the process," Gee said.
For RTX specifically, the clearance requirement acts as a hard filter that no AI can spoof. An active DoD clearance — especially TS/SCI with polygraph — is a binary credential tied to a person, not a résumé. That narrows the real applicant pool dramatically, which should shorten time-to-fill for cleared roles. But the surrounding noise (thousands of uncleared applicants auto-applying via AI tools) still clogs the top of the funnel. Recruiters spend cycles rejecting volume instead of engaging the few who qualify. The net effect: cleared, cross-domain engineers with hands-on integration experience move fast; everyone else hits a wall.
The practical takeaway for candidates is clear. Volume applications through portals yield near-zero return. The path through is demonstrable, verified work — public repositories, technical briefings, project artifacts — combined with a referral from someone the hiring team already trusts. RTX's screen now optimizes for that combination: clearance in hand, systems-integration proof in public, and a human vouch. The 179 roles will be filled, but not from the stack of AI-tuned résumés. They'll be filled from the network that already knows the work.
Three Units, Three Different Bars
RTX's three business units operate at distinctly different layers of the aerospace and defense stack, and the 179 openings (announced as a single corporate push) reflect that stratification. Collins Aerospace, the largest by headcount and product breadth, carries the heaviest share of requisitions. Pratt & Whitney's roles cluster around propulsion engineering and production scaling. Raytheon's openings concentrate on missile systems, radar, and the connected battlespace. The research does not publish a line-item split of the 179 across the three units, so the distribution below is reconstructed from each unit's public career pages, recent LinkedIn postings, and stated technology priorities.
Collins Aerospace: Breadth Across Airframe, Avionics, Mission Systems
Collins lists 2,263 open positions on its LinkedIn careers page alone, a figure that dwarfs the corporate 179 and suggests the announced number represents a prioritized subset, likely clearance-required or near-term-start roles. The unit organizes hiring around six technical pillars: aerostructures, avionics, interiors, mechanical systems, mission systems, and power and control systems. Each pillar maps to a distinct customer set: commercial airlines, regional and business aviation, military platforms, helicopters, space programs, airports, and air traffic control.
Recent LinkedIn postings (mid-July 2026) illustrate the range. A Sr. Design Engineer role sits in the Advanced Structures team, which "ensures structural integrity of aircraft and helicopters, helps platforms take off and land, move forward, transport cargo, and conduct rescues." An Electrical Engineer II, Digital Hardware and an FPGA Designer (Electrical Engineer II) both fall under Avionics, advancing "aviation electronics and information management solutions" for commercial and military customers. A Software Engineer, Embedded Communications (onsite) supports the Mission Systems team, which delivers "intelligent and secure communications, missionized systems for specialized aircraft and spacecraft, and collaborative space solutions." On the production floor, a Machinist IV (1st shift), a Mechanical Repair Technician III (first shift), and a 2nd Shift Finish Technician (onsite) reflect the Operations & Supply Chain hiring lane. A Senior Repair Operations Supervisor (2nd shift, onsite) and a Senior Lead Engineer, Projects round out the mix across engineering, quality, and aftermarket support.
Collins's career site also surfaces openings in Digital Technology, Finance & Legal, General Management, and Quality, functions that feed every technical pillar. The unit's stated mission ("redefine aerospace every day by breaking the status quo, sparking innovation, engaging employees, and delivering for customers globally") aligns with the screening emphasis on systems-integration experience: candidates who have moved hardware through qualification, not just designed it in isolation.
Pratt & Whitney: Propulsion Engineering and Production Velocity
Pratt & Whitney's career page frames its hiring around "investing in cutting-edge technologies and training to support our workforce and enhance engine production, with a focus on developing and growing our people amidst transformative changes." The language signals two parallel tracks: next-generation engine development (GTF, hybrid-electric, hydrogen-compatible cores) and rate acceleration on existing programs. Roles that appear in public postings skew toward mechanical design, thermal systems, materials science, and manufacturing engineering, disciplines where a security clearance is often mandatory because the work touches military engine variants (F135 for the F-35, F119 for the F-22) and classified propulsion research.
The unit does not publish a live job count comparable to Collins's 2,263, but its inclusion in the 179-role announcement indicates a meaningful slice. Given Pratt's current production bottlenecks (acknowledged in RTX's April 2026 "Scaling up to deliver with speed" release), a disproportionate share of its openings likely target manufacturing engineers, quality inspectors, and supply chain coordinators who can operate in a cleared environment. The screening priority for "hands-on project work" maps directly to Pratt's need for engineers who have run engine test cells, managed hardware builds, or led root-cause investigations on fielded hardware.
Raytheon: Missiles, Radar, Connected Battlespace
Raytheon's self-description ("brings together the best minds, systems and capabilities to create next-generation solutions that are smarter, faster and better than previously thought possible") reads as a recruiting pitch for systems architects and integration engineers. The unit's portfolio (Patriot, NASAMS, LTAMDS, SPY-6, hypersonics) is almost entirely classified or export-controlled. The May 2025 Patriot update ("proven in battle and still setting standards") and the May 2026 "commitment to lifesaving performance" release both underscore the operational tempo: fielded systems receiving software drops, radar upgrades, and interoperability patches on combat timelines.
Raytheon's share of the 179 roles almost certainly weights toward software-defined radio, signal processing, cyber-hardened embedded systems, and model-based systems engineering (MBSE). The screening filter for active clearances is strictest here; a Secret clearance is table stakes, and TS/SCI with poly is common for radar and missile software roles. The "cross-domain expertise" requirement in the corporate screen translates to Raytheon as fluency across RF hardware, real-time software, and operational doctrine, the profile of a systems engineer who has supported a flight test or a field deployment.
What the 179 Figure Represents — and What It Doesn't
The 179 number is a corporate communications artifact, not a real-time census. Collins alone shows 2,263 LinkedIn postings; Pratt and Raytheon each run their own career portals under the RTX umbrella. The announcement likely captures a tranche of priority requisitions, clearance-mandatory, near-term start, or tied to specific program milestones (Patriot PAC-3 MSE production, GTF rate ramp, LTAMDS delivery). It excludes backfill, intern pipelines, and roles that can be filled by uncleared candidates with export-control eligibility.
For applicants, the unit-level distinction matters. A Collins avionics role may accept a candidate with commercial aerospace DO-178C experience and no clearance, provided they can obtain one. A Raytheon radar software role will not. Pratt's manufacturing engineering roles often require ITAR-person status on day one. The screening priorities outlined in earlier sections (active clearance, systems-integration proof points, defense certifications) apply with different force depending on which business unit owns the requisition.
The Gate Holds
A recruiter evaluating a resume for a systems engineer role at Raytheon does not weigh the 401(k) match. The applicant tracking system does not filter for candidates willing to relocate to Tucson versus El Segundo. The hiring manager's first pass looks for an active Secret or Top Secret clearance, then for evidence that the candidate has integrated radar, propulsion, or avionics subsystems across mechanical, electrical, and software domains. That is the gate. Everything else (salary band, equity vesting schedule, relocation lump sum) becomes relevant only after the candidate clears it.
The SCIF door doesn't open for keywords. It opens for the engineer who can name the program, cite the standard, and show the metric, and who already holds the ticket that says they're allowed inside.
