Job description

Our client helps businesses win and deliver government contracts that advance American interests. Their AI platform is a single, secure, workflow-driven system for the full contracting lifecycle, from opportunity discovery and capture through proposal execution, award, and post-award operations.

In 2025 alone, customers won more than $5B in government contracts. We’ve raised $42M to move faster on product and scale nationwide.

• Improve system reliability, performance, and scalability as the platform grows.
• Continuously incorporate user feedback to refine features and deliver better customer outcomes.

What We’re Looking For

• 2+ years of professional software engineering experience.
• Strong full‑stack development experience with TypeScript / Node.js.
• Comfort working across frontend and backend systems (React‑based UIs and service APIs).
• Strong CS fundamentals, sound architectural judgment, and experience scaling production systems.
• Product‑oriented mindset and an obsession with customer experience and usability.
• Self‑starter with an ownership mentality who thrives in a fast‑paced startup environment.
• Clear communicator who collaborates effectively across disciplines.

Nice to Have

• Previous experience as a founder or engineer at a fast‑growing startup.fgov
• Experience building AI‑powered or LLM‑enabled product features.
• Experience with government contracting or public‑sector software.
• Experience with complex integrations and syncing with external systems.
• Work with React (TypeScript), Node.js, Next.js, Temporal, and modern cloud infrastructure.
• Move with speed and urgency without sacrificing quality.
• Embrace hard problems and take pride in elegant solutions.
• Put themselves in the shoes of users to build thoughtful, trustworthy experiences.
• Value clear, frequent communication and strong team ownership.
• Feel deep accountability and enjoy building for the businesses we serve.
