Senior Software Engineer

Odyssey Systems Consulting Group is seeking a Senior Software Engineer to join a multidisciplinary team focused on a high-performance Multimode Threat Engagement Simulation Platform. The role spans a Julia-backed physics server, a React/TypeScript front end with CesiumJS visualization, and CI/CD pipelines, all aimed at delivering robust scientific computing capabilities. The position offers a salary range of USD 130,000 to 160,000 per year and a hybrid work arrangement based in either Colorado Springs, CO or Boston, MA, with regular travel to support program needs.

Responsibilities

• Develop and optimize the Julia physics computation server, including trajectory integration with RK4/RK45 schemes via DifferentialEquations.jl, SGP4 orbital propagation using SatelliteToolbox.jl, and a Monte Carlo driver employing Threads.@threads for parallelism.
• Profile critical computation paths, benchmark throughput and latency, and ensure program requirements are met, such as executing 10,000 Monte Carlo runs within specified time limits.
• Integrate ONNX.jl surrogate model inference to enable real-time parameter sweeps, targeting sub-1 millisecond interactive latency.
• Generate CZML from physics outputs to drive time-dynamic Cesium visualization of trajectory arcs, orbital paths, and coverage footprints.
• Design and maintain the mission data model, including JSON serialization, a versioned file format with backward compatibility, and cross-platform path handling for Windows and Linux.
• Build an HTTP.jl API layer with clear request/response schemas, robust error handling, and structured logging.
• Create React/TypeScript components for the mission planning interface, including a tabbed overview, asset and task trees, parameter forms, and an analysis panel.
• Integrate and maintain the CesiumJS/Resium 3D globe, handling asset markers, trajectory rendering, satellite ground tracks, coverage footprints, and CZML-driven animation via the Cesium timeline.
• Manage frontend state for a data-heavy desktop application, covering mission data, UI state, and asynchronous physics query results.
• Develop data-driven visualizations of trajectories, Pk curves, and Monte Carlo distributions with libraries such as Recharts or Plotly.js.
• Oversee the CI/CD workflow in GitHub Actions, delivering Windows NSIS installers and Linux AppImages from a single codebase.
• Coordinate PackageCompiler.jl sysimage builds for the Julia physics server on target platforms, and manage electron-builder configurations and packaging scripts with verified installers on Windows and Linux.
• Embed ONNX models and asset resources at build time and manage versioning of bundled artifacts.

Requirements

• U.S. citizenship
• Active Secret clearance
• Bachelor's degree in Computer Science, Software Engineering, Electrical Engineering, Physics, or a related STEM field
• 5+ years of software development experience with demonstrated depth in at least one area such as scientific computing, numerical simulation, high-performance computing, or data-intensive desktop applications

Technologies

• Julia, DifferentialEquations.jl, SatelliteToolbox.jl
• ONNX.jl, CZML, CesiumJS, Resium
• HTTP.jl, JSON
• React, TypeScript, Recharts, Plotly.js
• GitHub Actions, PackageCompiler.jl, ONNX Runtime
• electron-builder, NSIS, AppImage
• Python with NumPy/Numba/Cython extensions

Benefits

• Medical, dental, and vision coverage
• Life insurance and disability (short- and long-term)
• Tricare supplement
• 401(k) with company match
• Flexible spending and health savings accounts
• Employee assistance program
• Learning and development opportunities
• Paid time off and holidays
