Top Tech Jobs & Startup Jobs in Los Angeles, CA

Lead design and implementation of pointing, acquisition, and tracking (PAT) for an FSO laser terminal. Develop algorithms and control loops for FSMs/precision actuators, create pointing budgets, build HIL testbeds, prototype and validate PAT performance, and support optical alignment and system testing across optics, photonics, and modem teams.

Analyze liquid rocket propulsion fluids systems and components, develop and validate analytical and CFD models, design tests and process data, automate data workflows, and coordinate with propulsion, test, GNC, structures, and integration teams.

Design, build, integrate, and support electrical ground support equipment (EGSE) for vehicle integration, engine testing, and launch operations. Own EGSE hardware lifecycle, create schematics and ICDs, troubleshoot and validate systems, collaborate with avionics/propulsion/software/test teams, ensure safety and reliability, and drive GSE process improvements. Mentor junior engineers for senior candidates.

Design, build, and operate optomechanical test setups for spacecraft components. Own test assets and programs, coordinate vendors, perform test setups, inspections, troubleshooting, data acquisition, and environmental qualification testing to rapidly develop flight hardware.

Lead a team designing spacecraft antenna and feed-network systems (1–30 GHz) from concept through prototype, lab characterization, and on-orbit support. Integrate with RF, avionics, and mechanical teams, optimize for mass/thermal/power constraints, perform EM simulations and desense analysis, and debug real-world antenna performance.

Design, build, and operate fluid, mechanical, and electrical test systems for liquid rocket propulsion and spacecraft hardware. Own test assets and programs, coordinate vendors, perform test setup and troubleshooting, run test operations, and collaborate across teams to rapidly develop flight hardware.

Lead certification activities for flight systems, analyze customer and government requirements, develop processes and documentation, support verification testing and demonstrations, interact with customers, and implement engineering and manufacturing changes to meet certification and mission readiness.

Lead design, analysis, testing, and implementation of storable liquid propellant systems. Architect fluid systems, plan and execute propellant/pressurization tests, resolve technical issues, coordinate across engineering, manufacturing, and operations, and lead small teams on propulsion development programs.

Lead design, analysis, and tuning of robust flight control algorithms for upper stages and landers. Produce stability analyses and verification data, contribute to GNC flight and simulation software, use SITL/HITL for evaluation, create GNC tools, mentor engineers, and communicate designs across teams to enable propulsive missions.

Lead design, installation, operation, and maintenance of cryogenic and industrial gas systems for spacecraft manufacturing and testing. Own system specifications, P&IDs, procedures, commissioning, troubleshooting, vendor management, and cross-functional coordination while ensuring compliance with safety codes and standards.
