Full Stack Developer

The Role: Full Stack Developer

We’re building a team of builders - engineers who love solving hard problems and bringing elegant software to life. Our Engineering Team is the engine behind Foundation Stack’s mission-driven data platform. You’ll design, build, and deliver tools that help our users see, understand, and act on the world in ways never before possible.

You’ll collaborate closely with a small, high-performing team where every line of code has an impact - on our product, on our users, and on national security.

What You’ll Do:

• Develop and deploy features that solve complex, mission-critical problems.
• Integrate backend services with our front-end, customer-facing web applications.
• Collaborate with a distributed team of developers and data scientists.
• Contribute to full-stack architecture discussions and improve system performance.
• Write clean, testable, and well-documented code that scales.

Who You Are:

You’re curious, driven, and relentless about quality. You think like an engineer and a product builder. You care about precision and performance, but also about the mission. You love learning new tools and technologies, and you thrive in an environment where no two days are the same.

• U.S. Citizenship (must be able to obtain a U.S. Security Clearance).
• Experience developing and testing JavaScript applications.
• Strong understanding of React, Next.js, or similar frameworks.
• Comfort working across front-end and back-end systems.

It’s Even Better If You Have:

• Experience with front-end technologies like JavaScript, TypeScript, React (Hooks, Router), Material UI, Next.js, and Node.js.
• Experience with back-end and database technologies such as Python, GRPC, and Docker, Kubernetes.

What You’re Signing Up For:

This won’t be easy. But it will be meaningful. You’ll be working at the intersection of cutting-edge AI, national security, and mission-driven technology. If you want to build software that truly matters - and be part of a team that moves fast, sweats the details, and cares deeply about impact -= this is your opportunity.

Additional Requirements:

• Willingness to work at our Tysons Corner, VA office at least once a week

• 401(k)
• Flexible schedule
• Paid time off

Application Question(s):

• This position may require a U.S. government security clearance. Are you a U.S. citizen and willing to undergo the clearance process if eligible?
• This position requires in-person work at our McLean, VA office at least one day per week. Do you currently live in the Washington, DC metropolitan area (DC, Maryland, or Northern Virginia)?
• What are your salary expectations or requirements for this position? We’d really appreciate a specific number or range to help us understand if we’re aligned. Applications that only say “negotiable” or don’t include a clear salary expectation may not be considered. Thanks for your understanding!
• Can you share a project you’re proud of - what did you build, what was your role, what technologies did you use, and what challenges did you overcome?

At Foundation Stack AI, we don’t build ordinary products. We build capabilities that redefine what’s possible for the U.S. Military and Intelligence Community. Today we lead the world in man-made Vertical Obstruction (VO) data. Tomorrow, we’ll lead in something even bigger: a global, AI-powered, human-machine teaming system for understanding the man-made world - faster and more precisely than ever before.

We can’t do it without people who care deeply about getting it right.
