Top Engineering Jobs in Los Angeles, CA

Own materials and processes engineering for thermal protection systems and non-metallic soft goods supporting Terran R flight and reuse. Define qualification envelopes, test plans, characterization campaigns, specifications, and engineering standards. Lead statistically driven experiments, process improvements, failure analyses, and material qualification. Collaborate with materials, laboratory, design, manufacturing, supply chain, reliability, fracture control, and leadership teams to resolve technical risks and improve performance, cost, quality, manufacturing rate, and reusability.

Own materials and processes engineering for Terran R avionics hardware. Qualify materials and processes for flight and reuse, develop technical specifications, lead statistically driven experiments, and support material selection, design, failure analysis, manufacturing, quality, and supply-chain activities. The role coordinates laboratory characterization, process development, subcontractor compliance, fracture-control efforts, technical roadmaps, and risk reduction across interdisciplinary teams.

Designs, analyzes, and builds hardware for Aeon-R rocket propulsion systems. Responsibilities include engine-level layout, mechanical design, fluid, thermal, and structural analysis, trade studies, and collaboration with propulsion, vehicle, manufacturing, integration, and test teams. The engineer will lead projects through completion and support hardware development across the product lifecycle.

Owns assembly, integration, and test campaigns for a Mars orbiter, from component testing through launch preparation. Develops procedures, test plans, acceptance criteria, verification approaches, tooling, ground support equipment, and campaign infrastructure. Leads thermal, vibration, EMI/EMC, functional, and end-to-end tests; conducts readiness reviews, analyzes results, resolves discrepancies, and drives root-cause closure. Maintains configuration and verification records while collaborating across hardware, software, and systems engineering teams.

Own propulsion test campaigns for Terran R engine assemblies, including test planning, execution, troubleshooting, data review, test sequencing, hotfire console operations, tooling design, and test article evaluation. Support engine subsystem investigations, systems analysis, simulations, trade studies, and efficiency projects. The role is onsite in Long Beach, includes rotating shifts, weekend milestone work, and approximately 25% travel to test and launch sites.

Build and maintain frontend platform capabilities for a unified rocket-factory operator UI. Develop React and TypeScript modules, shared components, design-system integrations, and real-time telemetry interfaces. Migrate features from separate frontends, optimize live-data rendering performance, contribute to code reviews, and collaborate with senior engineers on architecture. The role supports industrial automation and launch operations software.

Designs, verifies, synthesizes, brings up, and validates custom FPGA firmware and DSP pipelines for Relativity Space’s Terran R launch vehicle. Oversees FPGA development across the full product lifecycle, from concept through flight operations, including board bring-up, qualification, production, integration, and debugging. Requires expertise in digital communications, DSP, RTL development, high-speed data converter interfaces, FPGA toolchains, and mission-critical aerospace systems, along with strong cross-functional and project management skills.

Designs, builds, operates, and troubleshoots pressurized cryogenic, pneumatic, and hydraulic test systems for rocket testing. Develops real-time data control systems, creates test plans and procedures, advises engineers on testing practices, mitigates operational hazards, and improves hardware reliability. Requires a high school diploma or GED and at least four years of relevant technical experience with pressurized flight components, hazardous equipment, and complex fluid-mechanical systems.

Designs, verifies, synthesizes, validates, and tests FPGA firmware for Terran R launch vehicles. Owns FPGA development through the full product lifecycle, including board bring-up, qualification, flight production, integration, and vehicle operations. Collaborates with mechanical, thermal, electrical, software, propulsion, GNC, and other teams to deliver reliable digital electronics on schedule. The role also involves debugging, data analysis, timing analysis, and cross-functional project coordination.

Own reliability and quality initiatives across rocket design, manufacturing, testing, and launch operations. Responsibilities include design standardization, DFM, configuration control, work instruction review, process development, build verification, nonconformance management, as-built verification, root cause and corrective action, inspection automation, and quality documentation. The role collaborates extensively with engineering, additive manufacturing, production, test, and launch teams while establishing scalable quality processes for the Terran R program.
