Develop, qualify, and execute manual and semi-automated weld processes for aerospace flight hardware. Responsibilities include setting up welding equipment, developing weld parameters, performing weld repairs, loading hardware, installing tooling, conducting fit-up and dimensional inspections, blending surfaces, and resolving manufacturing issues. The role works with GTAW, GMAW, and laser welding on aluminum, stainless steel, and Inconel components while meeting aerospace quality and production standards.

Assist with friction stir welding operations, including equipment operation, weld preparation, post-weld blending, lifting, deburring, and precision in-process inspections. Use hand and power tools, micrometers, calipers, and pi tape while maintaining safety and shop cleanliness. The role requires experience with material joining, metal fabrication, and common inspection tools. Experience with rigging, cranes, machining, CNC, robotics, or NDT is preferred.

Lead reliability and quality engineering for rocket structures across design, manufacturing, testing, and launch. Responsibilities include drawing standardization, DFM, configuration control, work-instruction review, process development, build verification, nonconformance management, root-cause analysis, corrective actions, as-built verification, inspection initiatives, and cross-functional quality improvements. The role partners closely with engineering, additive manufacturing, production, test, and launch teams to establish scalable reliability processes for the Terran R launch vehicle.

Supports primary structure assembly on the shop floor, removes production barriers, improves manufacturing processes, creates work instructions and specifications, standardizes operations, and provides design-for-manufacturing feedback. Collaborates with design, manufacturing, reliability, production, and vendor teams during prototype and flight builds. Requires hands-on aerospace assembly experience, strong engineering fundamentals, and knowledge of drilling, trimming, fastening, machining, inspection, and GD&T.

Develop and maintain integrated production schedules from raw materials through final assembly. Identify and mitigate shortages, supply constraints, drawing-release delays, and process-planning gaps. Manage Clear to Build activities, resolve production constraints, and coordinate with engineering, supply chain, and production teams. Improve planning tools, reporting, and scalable automation to support high-mix manufacturing, rate-based production, build readiness, and rapid manufacturing execution.

Design, fabricate, operate, and maintain Terran R launch pad propellant and gas infrastructure. Perform fluid-system modeling, pipe stress analysis, drawings, component selection, and work instructions. Lead facility construction activation, commissioning, and initial operations while solving complex cross-disciplinary technical problems. The role requires hands-on hardware experience, project management, technical leadership, and knowledge of fluid mechanics, heat transfer, and pipe stress.

Maintain and troubleshoot Powder Bed Fusion printers, including preventive maintenance, laser optics inspections, calibrations, hardware repairs, and component testing. Manage critical spare-part inventories, help develop maintenance procedures, and train production staff on printer operations and daily maintenance. The role requires additive manufacturing experience, strong mechanical aptitude, tool proficiency, and knowledge of maintenance processes.

Designs, analyzes, tests, and supports manufacturing of primary and secondary rocket structures for Relativity Space’s Terran R vehicle. Owns components from requirements through production, including load-path conceptualization, structural sizing, CAD design, drawing release, hardware test campaigns, and manufacturing process development.
