Top Tech Jobs & Startup Jobs

The GNC Simulation Engineer II will develop and integrate flight algorithms, run simulations, and enhance dynamics models for aerospace vehicles, focusing on GNC and performance optimization throughout the mission.

Contribute to GNC simulation development, implement numerical solvers, integrate subsystems, and improve simulation environments in a fast-paced team focusing on aerospace vehicles.

Set up and operate CNC machinery, select tooling, monitor production quality, and collaborate with manufacturing engineers in a dynamic R&D environment.

The role involves developing machine learning systems for Mars atmospheric modeling and multi-modal data fusion, contributing to autonomous science in space missions.

Lead hands-on execution of avionics environmental testing (vibration, shock, thermal) for Terran R hardware. Set up, instrument, operate, troubleshoot, and teardown tests; run QTPs/ATPs; collect and deliver DAQ data; support test readiness, fixture setup, hardware integration, and collaborate with engineering, manufacturing, and quality teams to maintain flight readiness.

Lead integrated stage test campaigns for Terran R: develop and execute test plans, write test sequences, sit console for hotfire tests, troubleshoot systems in real time, decompose requirements, drive verification and risk mitigation, and coordinate cross-functional subsystem investigations. Travel to test and launch sites and work hands-on with hardware through qualification, acceptance, and launch campaigns.

As a Simulation and Modeling Engineer II, you'll develop flight algorithms and simulations for the Terran R rocket, integrating analysis and hardware models, improving development environments, and contributing to cross-functional software packages.

Design, architect, and implement scalable HRIS solutions and integrations across Workday (HCM, Payroll, Time). Build and optimize end-to-end data flows, configure Workday features and security, ensure data governance and audit readiness, and partner with HR, Payroll, Finance, and engineering to deliver a world-class HRIS platform.

Moonshot Engineers at Relativity Space will prototype and realize world-changing ideas, manage projects, and work across various disciplines in a high-autonomy innovation lab.

As a Senior Simulation and Modeling Engineer, you will develop and analyze simulations for GNC algorithms, implement numerical solvers, and enhance simulation environments, focusing on modeling aerospace vehicles.
