Top Tech Jobs & Startup Jobs in Los Angeles, CA

Owns reliability and quality engineering activities for Terran R rocket design and production. Responsibilities include build verification, work instruction and process development, nonconformance management, configuration control, root-cause and corrective actions, inspection initiatives, and cross-functional collaboration with engineering, manufacturing, test, and launch teams. The role is onsite for a weekend shift and requires aerospace manufacturing quality experience, familiarity with PLM, MES, ERP, QMS software, and GD&T.

Own and evolve scalable manufacturing and supply chain process infrastructure, including MRP, procure-to-pay, material movement, factory automation, and change management. Design technical workflows, integrate enterprise systems, improve data integrity and operational performance, and lead digital transformation initiatives. Partner cross-functionally with manufacturing, supply chain, engineering, finance, and operations teams to translate complex needs into reliable, scalable product solutions.

Develops dynamic loads, vibration, shock, and coupled-load analyses for Relativity Space’s Terran R launch vehicle and supporting hardware. Responsibilities include maturing hardware designs, generating load predictions, validating analytical models, developing qualification specifications, guiding structural design and testing, and collaborating across aerospace engineering teams. The role requires mechanics and vibrations knowledge, dynamic-response modeling, testing and instrumentation experience, engineering programming, and data analysis skills.

Supports vehicle-level integration and testing of Terran R across mechanical, fluid, electrical, and avionics systems. Authors and executes test procedures, leads test readiness, coordinates ground support equipment and instrumentation, performs pre-test walkdowns, mitigates hazards, and troubleshoots issues with Engineering, Production, and Test teams. The role operates on a first-shift, 50-hour weekly schedule with guaranteed overtime.

Designs, builds, operates, and troubleshoots pressurized cryogenic, pneumatic, and hydraulic test systems for rocket testing. Develops data control systems, creates test plans and procedures, advises engineers on testing practices, mitigates hazards, and improves hardware reliability. The role requires hands-on experience with pressureized flight components, hazardous equipment, and complex fluid-mechanical systems, plus proficiency in basic office software.

Plans, executes, and documents complex rocket factory test operations. Develops test plans, procedures, automation, and work instructions; leads Test Readiness Reviews; operates manual and computer-controlled systems; troubleshoots electrical and fluid systems; mitigates safety risks; and supports post-test analysis, continuous improvement, training, and test stand design feedback.

Owns mechanical and structural design, packaging, analysis, testing, and validation of secondary avionics structures for the Terran R rocket. Provides technical direction, approves designs and analyses, makes architecture-level tradeoffs, and leads cross-functional integration across avionics, fluids, dynamics, thermal, structures, and vehicle integration teams. Ensures hardware meets static, dynamic, and thermal flight environments while balancing mission requirements, producibility, schedule, and cost.

Develop and integrate Terran R vehicle build processes across the lifecycle. Own verification activities for integration, testing, and launch-site checkouts; support qualification, acceptance, and hotfire campaigns; write test objectives, matrices, and plans; resolve off-nominal manufacturing challenges; and balance technical, cost, schedule, performance, reliability, and launch-rate constraints. Collaborate across mechanical, fluids, avionics, manufacturing, and other engineering teams, with possible travel and shifted schedules for critical milestones.

Develop and scale manufacturing processes for rocket turbopump components and assemblies. Own manufacturing trades, fabrication, testing, tooling, and delivery of critical propulsion hardware while serving as the interface between design and manufacturing teams. Responsibilities include turbopump assembly, rotor balancing, tolerance analysis, structural proofing, leak checks, machining, additive manufacturing, and process optimization for flight engine production.
