Top Tech Jobs & Startup Jobs in Los Angeles, CA

Draft, review, and negotiate customer-facing launch and mission services agreements; own first-cut reviews and markups; maintain templates and playbooks; coordinate with Business Development, Finance, and Legal Operations; track contract milestones and obligations; support senior attorneys on complex transactions and help build scalable commercial contracting processes.

Lead design, analysis, testing, and implementation of in-house liquid propulsion components and subsystems. Plan and execute tests (engine hotfire, valve functional), perform thermal-fluids and materials trades, resolve technical issues, and coordinate across engineering, manufacturing, and operations to deliver flight hardware.

Lead and scale U.S. multi-state payroll operations for exempt and non-exempt employees across engineering, manufacturing, and corporate functions. Ensure accurate bi-weekly payroll processing, tax compliance, wage-and-hour adherence, payroll reporting for equity, and payroll-related controls. Implement scalable systems, manage payroll tax filings and year-end activities, support new facility payroll readiness, partner cross-functionally with HR/Finance, and serve as escalation point for complex payroll and compliance issues.

Lead design and optimization of in-space servicing missions: create CONOPS, maneuver plans, trajectory and budget analyses, build analysis tools, integrate results into proposals, engage customers, and coordinate with engineering for simulations and verification.

Own and develop star trackers and optical navigation systems. Implement GNC flight, analysis, and test artifacts; develop identification, attitude-resolution, and object-detection algorithms; support relative navigation; verify sensor performance via simulation and hardware; contribute to attitude determination, flight and simulation software, and ground/on-orbit tools. Mentor others at senior levels.

Perform fabrication, assembly, verification, and testing of propulsion, combustion, and electromechanical spacecraft hardware; maintain and calibrate test equipment; develop automated acceptance tests; troubleshoot fluid and electrical systems; create 2D drawings from 3D models; document results and provide technician training.

Design and realize spacecraft propulsion components from concept through production: create detailed CAD models and manufacturing drawings, perform fluid/thermal/structural analysis, support procurement, fabrication, assembly and testing, provide technical test support, and resolve technical issues.

Design, implement, validate, and maintain onboard image-processing and computer vision algorithms for spacecraft on microcontroller-class hardware. Collaborate with avionics, flight software, GNC, test, and mission teams to define performance requirements, build test tools and simulations, debug sensor bring-up and flight operations, and ensure robustness within constrained compute, memory, timing, and power budgets.

Design, test, and deliver flight RF embedded software for space missions. Implement RF communications requirements, DSP and calibration algorithms, RF control algorithms, FPGA/baseband bring-up, and collaborate with ground teams to develop and test satellite-to-ground data pipelines and RF system integration.

Develop and maintain KPI frameworks and automated test scripts to characterize passive and active antennas (1–30 GHz). Plan and run verification campaigns, analyze antenna pattern data, produce compliance reports, and design fixtures for subsystem integration and coexistence testing.
