Top Tech Jobs & Startup Jobs in Los Angeles, CA

Lead administration and optimization of Siemens NX and Teamcenter, manage part libraries, support NX-to-Teamcenter integration, resolve complex CAD issues, implement best practices for large assemblies and MBD, and lead upgrades and testing to ensure continuous production readiness.

Develop real-time, fault-tolerant embedded firmware for actuators and electromechanical control systems across launch vehicles and spacecraft. Implement closed-loop control, motor commutation, sensor feedback integration, and safety-critical state machines. Interface over CAN, SPI, UART, Ethernet, RS-422, and BISS-C; support testing, hotfire campaigns, and in-flight diagnostics. Produce unit-tested, production-quality firmware for harsh space environments.

Develop real-time, fault-tolerant embedded firmware to control rocket and satellite actuators and motor-driven devices. Implement closed-loop control, interface with various sensors and communication protocols, design safety-critical state machines, support testing and hotfire campaigns, and produce unit-tested production firmware for spacecraft and testbeds.

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.

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.

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 planning, coordination, and execution of spacecraft programs across development, qualification, acceptance, and flight campaigns. Own schedules, manage risks, define requirements, coordinate cross-functional teams (engineering, manufacturing, I&T, supply chain), track program health, support proposals, and document high-reliability processes to ensure timely delivery and mission success.

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 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.
