Position Summary We are seeking a Mid-Level Software Engineer to contribute to the development of the Multimode Threat Engagement Simulation Platform under the technical direction of the Lead and Senior Staff Engineers. You will build features across the stack — backend physics API endpoints in Julia, React/TypeScript UI components, and Cesium map view integrations — while growing your expertise in high-performance scientific computing and defense mission engineering applications.   This role is an opportunity to develop real depth in an intersection of disciplines that is rarely available at early career: scientific computing with Julia, 3D geospatial visualization with CesiumJS, and the physics of aerospace and defense sensor systems. You do not need to arrive with domain knowledge — you will acquire it through hands-on work alongside domain experts and through structured mentorship from the Lead Engineer. What you do need is a solid programming...

Position Summary We are seeking a Senior Software Engineer to be a primary technical contributor on the Multimode Threat Engagement Simulation Platform. You will own significant portions of the stack end-to-end — building the Julia computation backend, the React/TypeScript/CesiumJS frontend, and the CI/CD pipeline that delivers standalone Windows and Linux artifacts — with a primary emphasis on high-performance and scientific computing. You will work closely with the Lead Engineer on architecture decisions and with domain engineers (RF, EO/IR) to implement their physics models in a performant, maintainable form.   This role demands genuine depth in high-performance compute application development. The backend is not a conventional web API — it runs trajectory integration, Monte Carlo simulation across thousands of runs, and real-time surrogate model inference. You should be comfortable profiling and optimizing numerical code, reasoning about parallelism,...
