Top Tech Jobs & Startup Jobs in Los Angeles, CA

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.

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.

Lead design, analysis, test, and sustainment of the Helios Kick Stage vehicle. Manage a team of responsible engineers, define product roadmaps and engineering processes, drive component test campaigns, and coordinate across engineering, manufacturing, and operations to deliver a reliable, flight-ready space vehicle.

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.

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.

Lead and manage technical proposals for US government opportunities: write and edit proposal content, interpret complex requirements, coordinate cross-functional inputs, develop schedules and graphics, ensure compliance with submission rules, maintain proposal repositories, and support other teams with technical writing.

Own spacecraft build from assembly through launch vehicle integration. Execute system-level testing, lead system integration and activation with technician teams, manage multidisciplinary schedules, identify and drive resolution of build issues, and provide design feedback to improve spacecraft processing.
