Top Tech Jobs & Startup Jobs in Los Angeles, CA

Lead design, analysis, testing, and implementation of storable liquid bipropellant thrusters and subsystems. Plan and execute engine hotfire tests, perform thermal-fluid and materials trades, resolve technical issues, and lead small teams to deliver integrated, high-performance propulsion systems.

Technical authority for architecture, development, and mission success of interceptor spacecraft. Own system architecture, lead cross-functional trade studies, manage risk, oversee readiness/certification, resolve major anomalies, and coordinate with stakeholders across development, manufacturing, test, and operations.

Supervise test area and a team of ~10 technicians to run spacecraft component testing. Coordinate schedules and resources with engineering, maintain and troubleshoot test and shop equipment, calibrate instrumentation, verify and document flight hardware, drive root-cause for non-conformances, maintain process documentation, and support hiring and scaling of the test team. Must work shifts, lift 25+ lbs, climb ladders, and work in tight spaces.

Manage supplier quality by qualifying parts, auditing vendor processes, owning non-conformances (SDR/MRB/CAPA/RTV), driving corrective actions and continuous improvement, supporting containment and inspection, and collaborating with Engineering, Procurement, and Production to ensure reliable supplier performance.

Design, develop, and implement tooling, fixturing, and test/support equipment for metallic and composite spacecraft structures. Collaborate with designers, analysts, manufacturing, and supply chain to prototype and produce designs, support testing, and solve complex technical challenges with emphasis on speed.

Lead design, testing, and delivery of flight RF software for space missions. Implement RF software architectures, develop DSP and calibration algorithms, design RF control algorithms, bring up RF systems, and collaborate with ground software teams to test satellite-to-ground data pipelines.

Design, develop, integrate, and verify real-time flight software for GNC, command/telemetry, mission sequencing, autonomy, fault management, and closed-loop control. Implement deterministic features in an RTOS/embedded Linux environment, develop anomaly detection/mitigation, participate in code reviews, and support ground integration, testing, and on-orbit operations.

Design and deliver spacecraft solenoid valves from concept through production: create CAD models and drawings, perform fluid/thermal/structural/magnetic analysis, support procurement, fabrication, assembly, and test, and resolve technical issues.

Design, deploy, and own deterministic, time-synchronized infrastructure for hardware test facilities. Lead test stand deployments, manage networking (PTP/NTP), servers, virtualization, storage, hybrid cloud, IaC, backup/recovery, and security alignment with enterprise standards while supporting CI/CD and test operations.

Design, build, and maintain standardized electrical test hardware (DAQ, controls, power distribution, enclosures). Create schematics, BOMs, wiring diagrams, and documentation. Support procurement, fabrication, integration, commissioning, and troubleshooting. Collaborate with test ops, software automation, and IT for deployment and configuration of test assets.
