Lockheed Martin software engineering intern in 2026: pay, tech stacks, and cleared program access
Lockheed Martin hired over 13,000 new employees in 2025 and is on pace to match that number in 2026, with software engineering representing one of its fastest-growing technical disciplines. The Lockheed Martin SWE intern program places hundreds of students each summer across the company's four business sectors, working on projects that range from embedded flight software to data analytics platforms to AI-enabled mission planning tools. If you are evaluating a Lockheed Martin software engineering internship for summer 2026, here is a detailed breakdown of pay, technology stacks, location options, and the security clearance implications that define defense software careers.
What Lockheed Martin SWE interns actually earn
Lockheed Martin uses a tiered compensation structure for software engineering interns based on education level and academic progress. The 2026 rates reflect a modest increase over previous years.
| Education Level | Hourly Rate (2026) | 12-Week Summer Earnings |
|---|---|---|
| Sophomore (CS/SE/CE) | $27–$30 | $12,960–$14,400 |
| Junior | $30–$33 | $14,400–$15,840 |
| Senior | $32–$35 | $15,360–$16,800 |
| Graduate (MS/PhD) | $35–$38 | $16,800–$18,240 |
Levels.fyi reports a median of $32.25 per hour for Lockheed Martin SWE interns, which aligns with the junior-to-senior undergraduate range. Glassdoor data trends slightly higher, showing estimates of $38 to $49 per hour when factoring in reported bonuses and stipends — but the base hourly rate for most undergrad interns lands in the $27 to $35 range.
Additional compensation: Housing stipends of $2,000 to $4,500 per summer are provided for interns who relocate. Some locations offer a one-time travel reimbursement. Lockheed Martin does not typically offer signing bonuses for internships, but the return-offer package for converting to full-time often includes one.
Google, Meta, and Microsoft SWE internships pay $50 to $65 per hour with significant housing stipends. Lockheed Martin pays roughly half that hourly rate. The trade-off is access to classified programs, a direct path to a security clearance (which has significant long-term career value), and the opportunity to work on systems with real-world mission impact. Defense SWE interns who convert to full-time and hold a TS/SCI clearance command a permanent salary premium over their uncleared peers.
Technology stacks across the four sectors
The tech stack you work with as a Lockheed Martin SWE intern depends heavily on which sector and program you are assigned to. Defense software is not a monolith — it spans embedded real-time systems, enterprise web applications, data engineering pipelines, and AI/ML research.
Aeronautics (Fort Worth TX, Palmdale CA, Marietta GA)
Languages: C, C++, Ada (legacy systems), Java, Python for tooling and automation.
Domains: Flight control software, mission computing, sensor fusion, pilot vehicle interfaces. Aeronautics software runs on embedded real-time platforms where deterministic behavior and safety certification (DO-178C) are mandatory. Interns may work on unit testing, simulation environments, or tooling that supports the flight software development process.
Space (Littleton CO, Sunnyvale CA, Huntsville AL)
Languages: C++, Python, Java, MATLAB. Growing use of Rust for ground system components.
Domains: Satellite ground systems, orbit determination, command and telemetry processing, mission planning. Space sector SWE interns frequently work on ground software that operates satellites — processing telemetry data, scheduling ground station contacts, and automating operational procedures.
Missiles and Fire Control (Orlando FL, Grand Prairie TX)
Languages: C++, Java, C#, Python. Embedded C for real-time guidance systems.
Domains: Guidance, navigation, and control (GN&C) software, weapons system simulation, targeting algorithms, hardware-in-the-loop test environments. MFC has some of the most technically intense SWE intern assignments, particularly in simulation and modeling.
Rotary and Mission Systems (Moorestown NJ, Owego NY, Syracuse NY, Manassas VA)
Languages: Java, C++, Python, JavaScript/TypeScript for web-based mission systems.
Domains: Aegis combat system software, radar signal processing, electronic warfare systems, autonomous systems, and cybersecurity tooling. RMS offers the broadest variety of SWE work, from low-level signal processing to full-stack web applications for mission planning.
| Sector | Primary Languages | Clearance Requirement | Key SWE Intern Locations |
|---|---|---|---|
| Aeronautics | C++, C, Ada, Java | Secret (most roles) | Fort Worth TX, Palmdale CA |
| Space | C++, Python, Java | Secret to TS/SCI | Littleton CO, Sunnyvale CA |
| MFC | C++, Java, C# | Secret (most roles) | Orlando FL, Grand Prairie TX |
| RMS | Java, C++, Python, JS | Varies widely | Moorestown NJ, Owego NY |
Top intern locations and what to expect
Fort Worth, Texas
The largest Lockheed Martin campus and home to F-35 software development. Cost of living is moderate by major metro standards. No state income tax. The intern community is large — hundreds of students each summer — with organized social events, technical talks, and networking opportunities.
Denver and Littleton, Colorado
Lockheed Martin Space headquarters. Strong outdoor lifestyle appeal. SWE interns work on satellite ground systems and space vehicle software. Housing costs are higher than Fort Worth but well below California. The Denver tech scene provides additional networking value.
Moorestown, New Jersey
RMS headquarters, home to Aegis combat system development. Located in suburban South Jersey near Philadelphia. Good access to the Northeast corridor. SWE interns here work on some of the most complex real-time distributed systems in the defense industry.
When applying, you can specify location preferences. If you want the strongest technical SWE experience, Fort Worth (flight software) and Moorestown (combat systems) are hard to beat. If you want the best lifestyle during your summer, Denver and Orlando offer the most appealing non-work environments. Express flexibility — it increases your chances of receiving an offer.
Security clearances for SWE interns
Security clearances are a defining feature of defense software careers and a significant long-term career asset. Here is how they work for interns:
Clearance sponsorship: Lockheed Martin initiates the clearance investigation process for interns assigned to cleared programs. You must be a US citizen. The investigation covers your background, financial history, foreign contacts, and other areas.
Timeline: Secret clearances typically take 3 to 6 months. Top Secret investigations take 6 to 18 months. Some interns receive their clearance during the internship; others begin the process but do not complete it until they return full-time.
Interim access: While your investigation is pending, you may receive interim Secret access that allows you to work on classified material. This is common for interns with clean backgrounds.
Career value: A TS/SCI clearance takes significant time and money for an employer to obtain. Once you hold one, you become more valuable in the defense job market. Cleared SWE professionals command a salary premium of $10,000 to $25,000 over equivalent uncleared roles at defense contractors, government agencies, and intelligence community support organizations.
The application process
Lockheed Martin SWE internship applications open in August and September for the following summer. Here is the standard process:
Online application: Submit through lockheedmartinjobs.com or apply via campus career fairs. Include your resume, GPA (3.0 minimum, 3.3+ competitive), and relevant coursework or projects.
Technical screen: A 30 to 45 minute phone or video interview covering data structures, algorithms, and basic systems design. The difficulty level is below FAANG standards but requires solid CS fundamentals.
Behavioral interview: STAR-format questions about teamwork, problem-solving, and handling ambiguity. Defense companies weight behavioral fit heavily.
Offer and clearance: Offers are typically extended within 2 weeks of the final interview. Clearance paperwork follows the acceptance.
Converting to full-time
The return-offer rate for Lockheed Martin SWE interns is approximately 70 percent. Full-time entry-level SWE salaries in 2026 range from $80,000 to $100,000 depending on location and education level, with signing bonuses of $8,000 to $20,000 for returning interns. Total first-year compensation for a returning intern with a BS in computer science, including bonus and benefits, typically falls between $95,000 and $125,000.
Frequently asked questions
What programming languages should I know for a Lockheed Martin SWE internship?
C++ and Java are the most broadly used languages across all four sectors. Python is essential for scripting, automation, and data analysis. Familiarity with C is helpful for embedded systems work. Specific programs may use Ada, C#, Rust, or MATLAB, but you do not need to know these before starting.
Is a Lockheed Martin SWE internship worth it if I want to work in Big Tech later?
Yes, but for different reasons than you might expect. The technical work is often narrower and more specialized than Big Tech internships, but the security clearance, project management exposure, and systems engineering mindset you develop transfer broadly. Many engineers do 2 to 5 years at Lockheed Martin, establish their clearance, and then move to defense tech startups (Anduril, Palantir, Shield AI) that offer compensation closer to FAANG levels.
Do Lockheed Martin SWE interns work on classified projects?
Some do, depending on the program assignment and clearance status. Interns on classified programs work in secured facilities (SCIFs) and cannot discuss their project details outside the facility. Other interns work on unclassified programs or on the unclassified portions of classified systems.
What is the interview difficulty compared to Google or Meta?
Significantly easier from a pure algorithms perspective. Lockheed Martin technical interviews focus on practical coding ability — can you write clean code, debug effectively, and explain your design decisions? You will not face LeetCode hard problems, but you should be comfortable with arrays, linked lists, trees, sorting algorithms, and basic object-oriented design.
