Top Tech Jobs & Startup Jobs in Los Angeles, CA

Design, implement, and verify GNC algorithms and software for spacecraft (LEO/GEO, upper stages, landers). Develop flight and simulation code, generate verification data, create reusable tools, resolve technical issues, and communicate designs. Mentor others and define GNC best practices for senior roles.

Perform fabrication, assembly, verification, and testing of propulsion, combustion, and electromechanical spacecraft hardware; maintain and calibrate test equipment; develop automated acceptance tests; troubleshoot fluid and electrical systems; create 2D drawings from 3D models; document results and provide technician training.

Lead design and optimization of in-space servicing missions: create CONOPS, maneuver plans, trajectory and budget analyses, build analysis tools, integrate results into proposals, engage customers, and coordinate with engineering for simulations and verification.

Lead reliability for propulsion hardware across design, manufacturing, and flight. Investigate and eliminate build defects, develop inspections and acceptance criteria, perform development testing, provide design-for-reliability guidance, optimize MRP/ERP traceability, build quality metrics, train technicians, and drive corrective actions and supplier quality improvements.

Design, write, and debug flight and ground software integration/regression tests (simulation and hardware-in-the-loop). Implement tests in Python, support C/C++ debug, bring up Docker containers and HIL environments, integrate hardware emulators, automate tests in CI/CD, and collaborate with GNC and ops to create day-in-the-life spacecraft test scenarios.

Lead design and development of propulsion valves and fluid components (cryogenic, high-pressure, high-temperature). Create detailed CAD models and drawings, perform fluid/thermal/structural analyses, establish assembly procedures, support development and qualification testing, work hands-on with technicians, and resolve technical issues from concept to product realization.

Design, architect, and bring up high-speed digital circuit boards for software-defined radios on spacecraft. Develop schematics and layouts, perform signal integrity and timing analyses, run simulations, test hardware in lab and system-level RF environments, derive requirements, support qualification and flight operations, mentor junior engineers, and troubleshoot/fix lifecycle issues.

Analyze and create fluid system designs for spacecraft propulsion: perform fluids and thermal analyses, size PMDs, run CFD and multi-phase simulations, validate with testing, develop company-wide analysis tools, and mentor peers.

Lead design, implementation, integration, and verification of flight software for responsive high-performance spacecraft. Architect real-time systems for command/telemetry, mission sequencing, autonomy, and fault management. Develop closed-loop control and anomaly detection/mitigation, mentor engineers, and support mission operations, testing, and on-orbit troubleshooting.

Design, analyze, build, test, and integrate composite overwrapped pressure vessels (COPVs) and mounts from concept through production. Lead supplier engagement, DFM, test planning, qualification campaigns, structural sizing, and cross-functional collaboration to demonstrate flightworthiness.
