Software Engineer — Simulation, Optimization & Decision SupportJoin a team building mission-critical software that turns complex technical concepts into tools decision-makers actually rely on.
You’ll work across the full stack — from backend services to the interfaces that make sophisticated simulations and optimization models usable — and across the full lifecycle, from early prototyping through deployment.
We’re a small, collaborative group where engineers own real problems end to end.
If you like working close to the research, translating hard technical ideas into clean, maintainable software, and seeing your work go from whiteboard to operational use, this role is built for you.
- Build and scale full-stack applications supporting simulation, optimization, and decision-support tools
- Design backend services and APIs (Java, Rust, or similar)
- Build responsive, intuitive front-end applications (React, Type Script)
- Partner directly with researchers and end users to shape requirements and translate technical concepts into working software
- Contribute at every stage — prototyping, implementation, demos, and deployment
- Bachelor’s degree in Computer Science, Mathematics, Physics, Applied Math, or related field
- 5+ years of professional software engineering experience
- Strong experience with React, Type Script, and modern front-end tooling
- Experience building backend services/APIs in Java, Rust, or similar languages
- A track record of writing readable, maintainable, well-engineered code in a collaborative setting
- Comfort working directly with researchers, engineers, and end users to turn ideas into usable software
- Exposure to full-stack web development in any modern framework
- U.S. citizenship required; must hold an active Top Secret clearance
- Active TS/SCI clearance
- Experience with performance-sensitive, algorithmic, or parallel/concurrent software
- Background in defense, national security, or other mission-driven environments
- 3D, geospatial, or high-performance visualization experience (WebGL, OpenGL)
- Experience with distributed systems, databases, or messaging/async processing
- Familiarity with AI/ML-enabled software (LLMs, computer vision, model integration)
- Experience with cloud/containerized deployment (AWS, Docker, Kubernetes, CI/CD)
