Associate Software Engineer

Tria Federal delivers digital services and technology solutions that support the health and safety of veterans, service members and civilians. For two decades, federal agencies have relied on Tria companies to advance their critical missions and modernize their systems, so that they can uphold their commitment to the American people. Today, we are pushing the boundaries of possibility through partnerships and investments in artificial intelligence and emerging technologies, developing solutions for the biggest challenges that government will face tomorrow. We are proud to employ and support military veterans who bring mission-first mindset, technical expertise, and leadership qualities that strengthen our work. Veterans, transitioning service members, and military spouses are strongly encouraged to apply.

Tria Federal is assembling a small team of highly capable Full-Stack Engineers to design and build AI-enabled tools and platforms that solve real-world problems for federal missions.

This individual will help create systems that automate knowledge work, enhance human decision-making, and improve digital experiences for millions of Americans, from veterans and clinicians to public safety professionals.

As part of Tria Labs, you'll shape how generative and agentic AI redefines mission delivery, building internal AI products and embedding directly with program teams to make digital civic services smarter, faster, and more human-centered. This is a great opportunity to turn generative AI into agents that act, not just respond, and perform where it matters the most.
