| ID | 2026-8142 | Category | Software Development | Type | Full Time | Biweekly Hours | 80 | Location : Name | Colorado Springs, CO | Min | USD $130,000.00/Yr. | Max | USD $160,000.00/Yr. |
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, and making informed trade-offs between simulation fidelity and throughput.
***Contingent upon contract award***
High-Performance Computation Backend
- Profile and optimize computation-critical paths; benchmark throughput and latency against program requirements (e.g., 10,000 Monte Carlo runs within a defined wall-clock target)
- Integrate ONNX.jl surrogate model inference for real-time parameter sweep capabilities; ensure inference latency meets the <1ms interactive target
Frontend and Visualization
- Build React/TypeScript components for the mission planning interface: tabbed mission overview, asset and task tree views, mission parameter forms, and the analysis panel
- Integrate and maintain the CesiumJS/Resium 3D globe: asset markers, trajectory rendering, satellite ground tracks, coverage footprints, and CZML-driven animation with the Cesium timeline
- Manage frontend application state (mission data, UI state, async physics query results) using appropriate state management patterns for a data-heavy desktop application
- Implement data-driven analysis visualizations - trajectory plots, Pk curves, Monte Carlo distribution charts - using Recharts, Plotly.js, or equivalent
DevOps and Cross-Platform Packaging
- Maintain the CI/CD pipeline in GitHub Actions: automated builds producing Windows NSIS installers and Linux AppImages from a single codebase
- Manage PackageCompiler.jl sysimage builds for the Julia physics server binary on both target platforms
- Maintain electron-builder configuration and platform-specific packaging scripts; validate installer behavior on clean Windows and Linux test environments
- Implement build-time embedding of ONNX model files and asset resources; manage versioning of bundled artifacts
