Top Tech Jobs & Startup Jobs in Los Angeles, CA

Lead technical authority for ground fluid systems across spacecraft programs: design, build, test, and operate propellant handling infrastructure; author standards and procedures; lead propellant loading campaigns; mentor engineers; represent ground fluids in cross-functional reviews and launch operations; drive roadmap and resolve complex technical issues.

Lead manufacturing processes for propulsion system production including valve assembly, tube fabrication, pressure vessel and engine integration. Create work instructions, tooling/test requirements, and contamination-control protocols. Drive process improvements, root-cause analysis, corrective actions, and production layout changes to increase vehicle build cadence while collaborating with design and supply chain to resolve quality and schedule issues.

Own end-to-end manufacturing and integration processes for mission-critical payload systems. Develop work instructions, contamination control protocols, and acceptance tests. Interface with customers and design teams, lead root cause analysis, maintain traceable build records, and coordinate payload readiness with vehicle integration.

Own and optimize manufacturing processes for composite and metallic structural assemblies. Create work instructions and tooling, provide DFM feedback, enforce cleanliness and FOD control, lead non-conformance investigations and corrective actions, refine floor layouts and throughput, and coordinate incoming material inspection with supply chain to scale production cadence.

Lead spacecraft final assembly and integration: own sequences, procedures, tooling, and documentation; coordinate across structures, propulsion, avionics, and TPS; resolve interface conflicts; run readiness reviews, root cause analysis, and track integration metrics to meet production cadence.

Own and scale end-to-end manufacturing processes for propulsion hardware including valve assembly, tube fabrication, pressure vessel and engine integration. Create work instructions and process specs, enforce cleanliness and propellant compatibility, lead RCCA for nonconformances, define tooling and test requirements, collaborate with design and supply chain, and optimize work cell layouts to increase production cadence.

Design and validate spacecraft thermal and fluid systems via analysis, simulation, and testing. Size thermofluid networks, define hardware and operational requirements, support integration and manufacturing, characterize propulsion thermofluid performance, and develop data processing for ground and flight testing while collaborating across disciplines.

Lead mission planning and trajectory design for commercial reentry vehicles, implementing 6-DOF simulations, trajectory optimization, Monte Carlo dispersion analyses, and autonomous navigation algorithms. Collaborate with propulsion, software, and flight operations teams, develop mission operations tooling, support on-orbit/reentry operations, and drive new vehicle capability development.

Perform flight safety and reentry analyses to support FAA Part 450 and range safety licensing. Produce FHAs, FMEAs, fault-tree and debris/casualty modeling, establish real-time safety limits, support mission rehearsals and live recovery operations, and deliver regulatory artifacts and Methods of Compliance for launch and reentry authorizations.

Full-cycle technical recruiter supporting hardware and engineering hires (autonomous systems, propulsion, thermal, mechanical, structures). Source, screen, manage interviews, support offers, and own candidate experience. Maintain ATS records, build pipelines, and partner with hiring managers and coordinators.
