About Gallatin
At Gallatin, we are rebuilding logistics infrastructure for the national security missions of the United States and allied partners. We build AI systems that determine how logistics decisions are made — not just how they’re executed. From factory to foxhole, we operate at the layer where data becomes decisions, and decisions make the advantage.
About the Role
We’re looking to hire our set of Founding Hardware Integration Engineers to help take Gallatin’s software off the cloud and into the field. You’ll evaluate, design, and get our systems running on rugged edge compute, connected to sensors and tactical communications, and working reliably in disconnected, contested environments.
You’ll work alongside our infrastructure, fullstack, AI, and product teams, and directly with operators during tests, exercises, and operations. You’ll own integration work end to end with senior engineers around you to learn from and push on as well as junior engineers to help mentor and develop.
What You’ll Do
Integrate Software Onto Real Hardware
Integrate Gallatin software and hardware systems on rugged edge compute, vehicle-mounted systems, and fielded kits, from the bench to deployment
Bring up, configure, and harden Linux-based systems, including drivers, networking, and update processes
Connect our stack to sensors, radios, and tactical networks through standard interfaces and protocols
Make It Work in Hard Environments
Build and test for degraded, disconnected, intermittent, and low-bandwidth conditions
Support field tests,exercises and operations, troubleshoot failures on site, and drive fixes back into the system at rapid pace
Track down and solve issues across power, thermal, and environmental constraints
Strengthen the Integration Process
Contribute to repeatable processes for hardware configuration, test, and deployment
Write the test plans, documentation, and checklists that make fielding systems faster and more reliable
Evaluate hardware components and bring clear recommendations to the team
Partner Across the Stack
Work with software and AI engineers to surface real hardware limits early
Capture what operators tell you in the field and feed it back to product
Support security and accreditation work for systems that touch classified networks
What We’re Looking For
3+ years in hardware integration, systems integration, or embedded engineering
Solid Windows or Linux fundamentals: system configuration, networking, and troubleshooting
Hands-on experience with hardware interfaces and networking (Ethernet, serial, CAN, USB, IP networking)
Working proficiency in Python, C, or C++ for integration, tooling, and test
Comfort debugging hands-on with incomplete information
U.S. citizenship and an active Secret, Top Secret,TS/SCI clearance, or willingness to go through the process to obtain one
Based in El Segundo, or willing to relocate
Bonus Points
Experience integrating tactical radios, MANET, or SATCOM
Familiarity with the TAK ecosystem (ATAK, WinTAK, TAK Server)
Containers and fleet management at the edge (Docker, k3s)
Experience supporting RMF or ATO packages
Exposure to MIL-STD environmental testing (810, 461)
Military service or prior experience supporting operators in the field
Background at a defense hardware, robotics, or autonomy company
Mission and Identity
We are building the system that enables faster, smarter logistics decisions in contested environments, and we’re doing it with a team of seasoned entrepreneurs, operators, and technologists who have built and scaled solutions in this space before. We hold ourselves to an extremely high standard. We value clear thinking, direct communication, and the kind of ownership that doesn’t stop until something actually works.
Our mission is to create decision advantage when the stakes are the highest. If we succeed, the system doesn’t just run; it gets smarter. We’re not building AI for its own sake. We’re building it because faster, smarter decisions in the most demanding environments on earth can’t wait. If you want to work somewhere the stakes are real and the mission is urgent — you’ll fit in here.
Why Gallatin?
The logistics infrastructure that supports America’s warfighters and humanitarian disaster responders is overdue for transformation, and we are building it. From defense operations to disaster response, we’re solving the hardest problems that keep missions moving when it matters most. Join a team where the mission is the point.
Compensation
Gallatin offers competitive compensation commensurate with experience. Actual compensation may vary based on experience, skills, and location. In addition to base salary, we offer a generous equity grant, full healthcare coverage, 401(k), unlimited PTO, and the perks of working in a high-caliber, mission-driven environment.
Gallatin is an equal opportunity employer. We do not discriminate on the basis of race, color, religion, sex, national origin, age, disability, veteran status, sexual orientation, gender identity, or any other characteristic protected by applicable federal, state, or local law.
This position may require the ability to obtain and maintain a U.S. government security clearance. The successful candidate must be able to work in a classified environment when necessary.
We comply with the United States Department of Labor’s Pay Transparency provision.

Integration Engineer Jobs in El Segundo: Frequently Asked Questions
How do I get a integration engineer job in El Segundo?
Focus on El Segundo's dominant sectors: aerospace and defense, satellite and communications technology, and enterprise software. Employers in the Aviation Boulevard corridor and El Segundo Business Campus hire integration engineers who can work across hardware-software boundaries or systems interfaces. Experience with defense standards, embedded systems, or API and data pipeline integration gives candidates a clear edge in this market. Tailoring your resume to systems complexity and cross-team coordination is especially effective here.
Which companies hire integration engineers in El Segundo?
El Segundo integration engineer roles are posted by The Aerospace Corporation, Trinzic, and MTSI and others right now, based on current listings on Migrate Mate as of November 2026. El Segundo attracts a mix of large defense primes, satellite operators, and mid-size technology firms, many of which run long-term programs requiring dedicated integration teams.
Are there remote integration engineer jobs in El Segundo?
Yes, though availability depends on the role: software and API integration positions are more remote-friendly, while systems and hardware integration roles typically require on-site work given lab access and secure facility requirements common in El Segundo. About 12% of integration engineer openings tied to El Segundo are remote or hybrid as of November 2026, with the highest remote share in enterprise software and cloud integration rather than aerospace or defense programs.
How can I get a integration engineer job in El Segundo with little or no experience?
The most realistic entry path in El Segundo is through junior systems analyst or associate integration roles at mid-size aerospace subcontractors and technology vendors in the Aviation Boulevard corridor. Many defense-adjacent firms hire entry-level candidates with relevant project work, internships, or certifications in systems integration or middleware. Demonstrating familiarity with tools like MuleSoft, Boomi, or JIRA, and any hands-on experience connecting disparate systems, helps candidates stand out with El Segundo employers who prioritize practical problem-solving over years of experience.
