Northrop Grumman security jobs in 2026: clearances, SCIF roles, and salary breakdown

Northrop Grumman's classified portfolio, including the B-21 Raider stealth bomber, the Sentinel (GBSD) ICBM replacement, and multiple compartmented space programs at its Space Park facility in Redondo Beach, drives one of the largest security hiring operations in the defense industry. The company employs security professionals across physical security, cybersecurity, industrial security (NISPOM compliance), and special program security, with most roles requiring TS/SCI clearance or higher.

Here is the complete breakdown of security job types, salary ranges, clearance requirements, and how to break into this field at Northrop Grumman.

Types of security roles at Northrop Grumman

Northrop Grumman organizes its security workforce into four primary categories, each with distinct qualifications and career paths:

Physical security specialists manage access control, alarm monitoring, visitor processing, and perimeter protection at Northrop Grumman facilities. Entry-level roles may require only a Secret clearance, but positions at facilities housing classified programs (Redondo Beach, Palmdale, Baltimore) typically require TS/SCI. Physical security officers conduct security rounds, manage badge systems, and coordinate with local law enforcement during incidents.

Cybersecurity analysts and engineers protect Northrop Grumman's networks, classified IT systems, and program data from cyber threats. Roles include Security Operations Center (SOC) analysts, vulnerability assessment engineers, incident response specialists, and cybersecurity architects. These positions require both technical expertise (SIEM tools, network forensics, penetration testing) and active clearances.

Industrial security specialists (ISSM/ISSO) ensure compliance with the National Industrial Security Program Operating Manual (NISPOM), now 32 CFR Part 117. They manage facility clearances, process personnel security clearances through DISS, conduct self-inspections, and prepare for Defense Counterintelligence and Security Agency (DCSA) assessments. ISSMs are the primary interface between Northrop Grumman and the government on all security matters.

Special program security officers manage access to SAP (Special Access Programs) and SCI (Sensitive Compartmented Information) programs. These are the highest-level security roles, requiring TS/SCI with polygraph and deep knowledge of program protection plans, OPSEC, and compartmentation. SAP security officers at Northrop Grumman often support B-21, classified satellite programs, or intelligence community contracts.

SCIF roles and classified program security

Northrop Grumman operates SCIFs (Sensitive Compartmented Information Facilities) at multiple locations. Working in a SCIF environment comes with unique requirements and conditions:

SCIF-based positions involve working in windowless, access-controlled spaces where electronic devices (phones, smartwatches, fitness trackers) are prohibited. You go through physical security checkpoints daily, and all materials you work with stay inside the SCIF. Roles based in SCIFs include security officers who manage the facility, system administrators who maintain classified networks (JWICS, SIPRNet), and program security officers who control access rosters.

Key SCIF locations at Northrop Grumman include:

Location	Division	Key Programs	SCIF Security Roles
Redondo Beach, CA	Space Systems	Classified satellites, missile defense	SAP security officers, ISSMs
Palmdale, CA	Aeronautics	B-21 Raider	Program security, physical security
Baltimore/Linthicum, MD	Mission Systems	Electronic warfare, C4ISR	Cybersecurity, ISSO roles
Melbourne, FL	Space Systems	James Webb follow-on, missile warning	Industrial security specialists
Colorado Springs, CO	Space Systems	Space situational awareness	ISSM, cyber analysts
Huntsville, AL	Defense Systems	Sentinel ICBM, IBCS	Program protection officers

Clearance requirements explained

Security clearance levels at Northrop Grumman follow the standard government framework, but the specific requirements vary by program:

Clearance Level	Processing Time	Roles Requiring It	Investigation Scope
Secret	3-6 months	Physical security, entry-level ISSO	T3 (5-year scope)
Top Secret	6-12 months	Mid-level industrial security, cyber	T5 (10-year scope, subject interview)
TS/SCI	8-14 months	Program security, SCIF-based roles	T5 + SCI adjudication
TS/SCI + Poly	12-18 months	SAP security, intelligence programs	T5 + SCI + polygraph exam

All clearance positions at Northrop Grumman require U.S. citizenship. The company cannot sponsor clearances for non-citizens. Permanent residents and dual citizens face additional adjudication considerations.

The investigation process examines your financial history, criminal record, foreign contacts, drug use history, and personal conduct. Common disqualifiers include recent illegal drug use (within 1-3 years), significant unresolved debt, undisclosed foreign contacts, and dishonesty during the investigation. Northrop Grumman's security team provides guidance throughout the process, and having a blemish does not automatically disqualify you, but full disclosure is mandatory.

How to apply and get hired

Northrop Grumman posts security roles on its careers portal (ngc.com/careers) and on job boards. The hiring process for security roles typically takes 4-8 weeks for candidates with active clearances and 3-6 months for those needing clearance sponsorship.

Step 1: Tailor your resume. Emphasize clearance status, specific NISPOM/32 CFR 117 experience, security tools (DISS, NISS, eQIP), and relevant certifications. Use the exact terminology from the job posting.

Step 2: Apply through the portal. Northrop Grumman's ATS uses keyword matching heavily. Include both spelled-out terms and acronyms (Information System Security Manager / ISSM).

Step 3: Phone screen. A recruiter verifies clearance status, salary expectations, location flexibility, and basic qualifications. This call typically lasts 20-30 minutes.

Step 4: Technical interview. For cybersecurity roles, expect scenario-based questions about incident response, network security, and compliance frameworks. For industrial security, expect questions about NISPOM, DCSA inspections, and personnel security processing.

Step 5: Panel interview. Senior roles involve a panel of 3-4 interviewers from the hiring program and the security organization. They assess both technical knowledge and cultural fit.

Step 6: Offer and clearance processing. Conditional offers are extended pending clearance verification or initiation. Start dates may be delayed if your clearance is not yet active.

Frequently asked questions

Do I need a clearance before applying to Northrop Grumman security jobs?

Not always. Northrop Grumman sponsors clearances for qualified candidates. However, candidates with active clearances are strongly preferred because they can start immediately. Entry-level physical security and some industrial security associate roles may accept candidates eligible for Secret clearance, meaning the company will initiate the investigation after hiring.

What is the difference between ISSM and ISSO at Northrop Grumman?

The Information System Security Manager (ISSM) has overall responsibility for the security program of one or more classified information systems and serves as the primary government interface. The Information System Security Officer (ISSO) supports the ISSM and handles day-to-day security tasks for specific systems. ISSMs earn $10K-$25K more than ISSOs at the same experience level and typically require CISSP certification.

How long does it take to get a TS/SCI clearance through Northrop Grumman?

Processing times vary, but expect 8-14 months for a TS/SCI investigation. Simple cases with no foreign contacts, clean financial history, and no drug use history process faster. The polygraph adds 2-4 months if required. Northrop Grumman's Facility Security Officer manages the process and can provide status updates.

Can Northrop Grumman security experience transfer to other defense contractors?

Yes. Security clearances are held by the government, not the employer. If you leave Northrop Grumman with an active clearance, other defense contractors and government agencies can sponsor your clearance without a new investigation (within 24 months of last active clearance). NISPOM, RMF, and DCSA compliance skills transfer directly to any cleared facility.

What military security roles translate to Northrop Grumman positions?

Military Occupational Specialties (MOS) in security translate well. Army 35-series (Intelligence), Navy CTI/CTR/CTN, Air Force 1N and 3D series, and Marine 02 and 06 series all have direct equivalents. Military security managers and ISSOs often enter Northrop Grumman at mid-career salary levels with their existing clearances.
