  • Build responsive, usable, and intuitive frontends that present complex data and workflows clearly to users
  • Contribute across the full development lifecycle, including concept exploration, prototyping, implementation, testing, demonstration, deployment, and sustainment
  • Collaborate closely with multidisciplinary teams to understand user needs and deliver practical, high-impact solutions
Required Qualifications

  • At least 2 years of professional software development experience
  • Strong foundation in object-oriented design and software development, with experience in Java, C++, Rust, or other comparable programming languages
  • Experience creating backend software and/or APIs in collaborative production or prototype environments
  • Strong engineering fundamentals, sound technical judgment, and the ability to collaborate effectively with researchers, engineers, and end users
  • U.S. CITIZENSHIP REQUIRED; successful candidates will be subject to a security investigation and must meet eligibility requirements for access to classified information
Desired Qualifications
  • Active SECRET security clearance
  • Experience writing high-performance, multi-threaded (parallel/concurrent) software
  • Experience developing high-quality software in an environment where readability, maintainability, testing, and disciplined engineering practices are valued
  • Experience in defense, national security, or other mission-driven environments
  • Experience with TypeScript and React or other modern frontend development frameworks
  • Experience with 3D, geospatial, or high-performance visualization technologies such as WebGL or OpenGL
  • Experience with data-intensive or distributed systems, including databases, messaging systems, and asynchronous processing
  • Familiarity with AI/ML-enabled applications, including LLM-integrated systems
  • Experience with cloud and containerized deployment environments such as AWS, Docker, Kubernetes, and CI/CD pipelines
