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.

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 RF test strategy, design automated Python-based test infrastructure, and perform system-level validation and characterization of GNSS receivers, radios, antennas, and other RF hardware across engineering, integration, and production 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 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.

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.

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.
