Software Engineer

Software Engineer The Mission Do you want to build software that solves the world's most complex national security problems? At STR, we don’t just write code; we bridge the gap between cutting‑edge research and real‑world mission success. You will join a multidisciplinary powerhouse of software engineers, physicists, mathematicians, and data scientists dedicated to taking innovative ideas from a whiteboard concept to a mature, deployed implementation. The Technical Frontier As part of the Knowledge Exploitation & Decisions Systems Group, you will work at the intersection of AI and human decision‑making. Our portfolio is diverse and high‑impact, including Command & Control (C2) via intuitive human‑machine interfaces that help operators make the best possible decisions in high‑pressure environments; Trusted AI & Autonomy via simulation platforms to test AI autonomy and evaluate the reliability and responsibility of autonomous systems; and Advanced Reasoning via graph‑based reasoning and evolutionary algorithms for resilient workflow optimization, and enhancing language models to assess the feasibility of scientific claims. What You’ll Do Build & Scale: Design and implement flexible microservices within a robust DevSecOps ecosystem. Drive Deployment: You will initially support a mature mission planning solution, guiding it through the critical transition from R&D into an active user community. Collaborate: Work alongside scientists and engineers to turn complex mathematical models into production‑grade software. Own Your Growth: Beyond your initial project, your trajectory will be driven by the intersection of your interests and our portfolio. Who You Are Education: BS/MS in Computer Science or a related technical field. Experience: 2+ years (BS) or recent MS graduate with professional experience building maintainable, well‑documented APIs and software in Java. Mindset: You are a "trailblazer"—someone who is comfortable with ambiguity and loves learning new libraries and languages on the fly. Our Tech Stack Primary: Java 17+, Spring Boot Infrastructure: Linux, Docker, Kubernetes, Kafka/NATS, GitLab Secondary: Python (for AI/Data integration) Logistics Location: Hybrid at one of STR’s offices in Woburn, MA; Arlington, VA; Carlsbad, CA; or Aurora, CO. Travel: Periodic travel up to 20% Clearance: US Citizenship required with the ability to obtain a Top Secret clearance.
