Polyrhythm builds software and systems for defense programs that need capability integrated, tested, secured, and ready to move.
Small. Deliberate. We embed with program offices, primes, and technical teams to clarify interfaces, produce evidence, and move software through integration with less friction.
Mission systems, modeling and simulation, aircraft software, secure infrastructure, and hard systems software depend on the same things: clear interfaces, reviewable evidence, and delivery paths that survive real constraints.
Capability schematics
Modeling & Simulation
Mission-level models, simulation tools, and LVC environments for red/blue analysis, scenario discipline, and repeatable decision support.
- → LVC integration
- → Red/blue mission context
- → Model and scenario discipline
- → Analysis evidence
Aircraft Mission Systems
Aircraft display software, mission-system interfaces, telemetry paths, and integration support for crewed and uncrewed platforms.
- → Mission Systems software
- → Display and compute integration
- → Flight-test instrumentation
- → DO-178C-aware engineering
Software Engineering
Software architecture, implementation, secure delivery, and evidence for systems close to hardware, sensors, models, data, and constrained environments.
- → Hard systems software
- → Architecture and interfaces
- → Secure delivery paths
- → Engineering evidence

Engineers who would rather field one thing that works than design ten that don't ship.
Mission systems, modeling and simulation, aircraft software, secure infrastructure, and hard systems software. Open source when the work and customer environment allow it. Small teams, real programs, working code.
