GNC Simulation Engineer: Swarm/Vehicle (HOOTL) with Equity

Rendezvous Robotics; Golden (CO); On-site; USD 110,000 - 170,000; Full time

Benefits offered by this job

Stock options

Comprehensive health coverage

Paid vacation 3 weeks + 10+ holidays

Job summary

Rendezvous Robotics in Golden, Colorado, is seeking a GNC Engineer, Simulation (Swarm/Vehicle) to own the HOOTL simulator that verifies flight software against a high‑fidelity physics world. You will model vehicle dynamics, docking, and the environment, and run Monte Carlo campaigns across GNC, embedded software, and hardware teams.

This role requires strong C++ and Python skills, experience in real‑time software, high‑fidelity 6DOF simulations, numerical integration, and hardware‑in‑the‑loop

Qualifications

• Bachelor's degree in aerospace/mechanical/electrical engineering, physics, mathematics or other relevant engineering discipline.
• Software development experience in C++ and Python.

Responsibilities

• Develop highly reliable, performant simulation infrastructure, physics models, tools, and dashboards in C++ and Python.
• Build and own the HOOTL framework that runs the actual flight software against a high‑fidelity physics world.
• Implement the physics truth model (numerical integration, electromagnetic forces and torques, contact, and constraints) and lower‑fidelity onboard models with a verified fidelity switch.
• Develop models of the tile sensor and actuator suite consistent with the GNC physics models.
• Emulate the distributed, multi‑rate node graph and its inter‑node transports so every discrete element advances on its own clock.
• Build Monte Carlo and scenario campaign tooling—configuration, scheduling, logging— and per‑node telemetry and observability.
• Run the regression and verification campaigns that gate every control and navigation claim, and integrate subsystem models with analysis and embedded‑software teams.
• Support flight operations by maintaining sim‑to‑flight correlation and reproducing on‑orbit behavior for anomaly investigation.
• Extend the framework to the assembled spacecraft—vehicle‑level dynamics, the changing inertia of a reconfiguring structure, and the absolute space environment.
