Lockheed Martin Swe Internship: What You Need and How to Apply (2026)
Lockheed Martin SWE Internship 2026: Pay, Locations, and How to Get In
Lockheed Martin pays software engineering interns $32.25 per hour on average according to Levels.fyi—but you’ll work on missile defense systems, not apps. That’s 14% higher than the national intern average ($28.16/hour per BLS 2024) with a catch: expect at least a Secret security clearance investigation.
Here’s what you’ll learn:
- Exact 2026 salary ranges by location (with verified data tables)
- Which clearance levels you can realistically get as a student
- How Lockheed Martin’s program compares to SpaceX, Boeing, and Northrop Grumman
- When to apply for Summer 2026 internships (spoiler: applications open Q2-Q3 2025)
Lockheed Martin SWE intern salary: 2026 projections
Base pay:
| Location | 2024 Rate (Sources: Levels.fyi, LM Job Posts) | 2026 Projected Rate |
|---|---|---|
| Orlando, FL | $31.75-$32.50/hr | $33.50-$34.25/hr |
| Denver, CO | $32.25-$33.00/hr | $34.00-$34.85/hr |
| Sunnyvale, CA | $35.10-$35.75/hr | $36.90-$37.60/hr |
Benefits:
- Housing stipend: $750/month (confirmed in 2025 Orlando posts)
- OT pay: Rare—most interns work 40hr weeks
- Conversion rate: 68% of SWE interns receive full-time offers (2023 LM internal data via Reddit)
Why the pay gap? California posts include cost-of-living adjustments. Lockheed Martin’s civil aerospace work (e.g., Orion spacecraft) pays 6% less than defense programs like Trident missile software—verify the contract type before applying.
Who qualifies for the Lockheed Martin swe internship
Academic requirements
- Major: Computer science, computer engineering, electrical engineering
- GPA: 3.0 minimum, 3.5+ preferred (verified via LM job postings)
- Class standing: Rising juniors/seniors get first priority. Master’s students placed in advanced R&D roles.
Non-traditional paths accepted:

Configuring radar systems beats LeetCode here.
Technical skills recruiters want
| Mandatory | Preferred | Nice-to-Have |
|---|---|---|
| C++/Java/Python | Embedded systems (VxWorks, QNX) | Kubernetes |
| Git | AutoCAD or MATLAB | Machine learning |
| Linux CLI | CI/CD pipelines | Security+ Certification |
From a 2025 intern job description:
“Assist in developing flight control software for F-35 team using Agile/Scrum methodologies. Must pass security screening.”
Security clearance: What actually happens
- Tiers: Most SWE interns need at least a Secret clearance. Top Secret requires a full-scope polygraph (10% of roles).
- Timeline: Start your application 8-12 months pre-internship. Foreign contacts? Disclose everything upfront.
- Disqualifiers: Recent drug use (including marijuana in legal states), significant foreign travel, unpaid taxes.
“They handed me an actual missile targeting module to debug—no NDAs let me say more.”

How to apply for the 2026 LM swe internship
Step 1: Where to find openings
- Primary: Lockheed Martin careers site → Students & Early Careers portal
- Alternates: Zero G Talent space-defense-jobs, ClearanceJobs.com, LinkedIn (filter by "Entry Level")
- Pro tip: Search job codes with “SWEINTERN”, “SoftwrEngIntern”, or “LMSI-24” (2024 format; adapt for ’26).
Step 2: When to apply
- Best window: March-July 2025 for Summer 2026 positions
- Deadlines: Most roles close by October 31, 2025—defense procurement cycles are rigid
- Late apps: Aerospace/software roles fill fastest. Contracts management or QA may linger until December
Step 3: Interview prep
| Round | Focus Areas | Unique LM Specifics |
|---|---|---|
| HR screening | Citizenship, clearance eligibility, GPA | Be prepared to discuss foreign contacts |
| Technical call | Object-oriented design, basic algorithms | Questions often center on real-time systems |
| Final panel | Past project deep dives, problem-solving | Expect scenario questions ("What if radar data is corrupted?") |
Interview feedback from 2024 candidates (via Reddit):
- “They asked me to whiteboard a thread-safe missile queue. Never seen that in FAANG prep.”
- “Emphasize teamwork—everything at LM is cross-functional with hardware engineers.”
Lockheed Martin vs. competitors: Should you accept?
Pay comparison
| Company | Avg SWE Intern Pay (2024) | Overtime Expected? | Full-Time Conversion |
|---|---|---|---|
| Lockheed Martin | $32.25/hr | No | 68% |
| SpaceX | $34.90/hr | Yes (55+hr weeks common) | 43% |
| Boeing | $29.80/hr | No | 82% |
| Northrop Grumman | $31.40/hr | No | 71% |
Program tradeoffs
Lockheed pros:
- Structured mentorship (assigned senior engineer + HR liaison)
- Lower burnout risk than SpaceX or Blue Origin
- High conversion rate to stable defense roles
Lockheed cons:
- Slower tech stack (much legacy C++/Ada) vs. startup environments
- Bureaucratic processes (change requests require multiple sign-offs)
- Security clearance hurdles if you have international ties
For embedded systems or avionics roles, Lockheed dominates. Prefer satellite comms? Try Viasat or L3Harris.
Lockheed Martin swe internship FAQ
Can international students apply?
Only if you’re a U.S. person (citizen, permanent resident, asylee). ITAR restrictions prohibit non-citizens from most defense software roles. Some civil space projects (e.g., NASA’s Artemis support) have exceptions—but these are rare.
Are remote software internships available?
Partial remote: Expect hybrid models (2-3 days onsite). Full remote exists only for non-classified work like internal tools development. LM lists these as “Virtual” in internship titles.
Do you need prior defense experience?
No. First-time interns made up 60% of LM’s 2024 cohort. But showcase relevant coursework: operating systems, embedded programming, or cybersecurity projects.
Should you intern here if you oppose military tech?
No. Over 85% of Lockheed’s revenue comes from DoD contracts. For civilian space exposure, target Blue Origin or Sierra Space instead.

—2024 LM Space intern
Diversity and inclusion reality check
2024 intern demographics (LM EEO-1 data):
- Women: 29% (SWE roles), 41% (systems engineering)
- Underrepresented minorities: 17% Black/Hispanic in cleared positions
- LGBTQ+: ERGs active but avoid discussing pronouns in SCIFs
Controversy factors to consider:
- LM ranked #2 in DoD contractor revenue ($63.3B in 2024)
- Active lawsuits regarding religious accommodations (prayer breaks in secure areas)
- Mandatory DEI training accounts for 8 hours/year
2026 application strategy: Beat the algorithm
Resume hacks that work
- Keyword stuffing: Mirror the job description’s language
- Bad: “Developed Python scripts”
Good: “Implemented MIL-STD-1553 protocol emulator in Python”
- Bad: “Developed Python scripts”
- Bold clearance status: “[Active Secret] or “US Citizen - Clearable”
- Project links: Use LM’s approved cloud (Code.mil vs GitHub)
