Build and maintain a unified frontend platform for rocket factory operator applications. Develop React modules, shared components, design system features, and real-time telemetry interfaces. Migrate features from separate frontends, optimize live-data rendering, and contribute to shared architecture and code reviews. Collaborate with senior engineers while improving frontend performance, state management, and platform scalability.

Own the frontend platform powering Relativity Space’s operator UI, including the application shell, design system, shared data layer, and modular architecture. Lead consolidation of multiple frontends, support high-rate hardware telemetry rendering, establish frontend technical standards, and mentor engineers. The role requires deep TypeScript and React expertise, performance optimization for data-intensive applications, scalable state management, and cross-team architectural leadership.

Owns engine or vehicle hardware from design release through build, test, and delivery. Develops build flows, work instructions, and test procedures; supports first-article builds; resolves manufacturing issues and non-conformances; conducts root-cause analysis; coordinates design, supply chain, production, and test teams; and helps establish scalable tooling, ERP/MES workflows, and production documentation for aerospace manufacturing.

Leads the avionics survivability team for Terran R, ensuring electrical and electronic systems withstand launch and space environments. Oversees EMC, radiation effects, component reliability, requirements, risk mitigation, analysis, test planning, qualification, and verification across the vehicle. Coordinates with multidisciplinary engineering teams and external stakeholders, drives compliance with industry standards, and influences design decisions from early development through flight. The role also manages complex EMC, radiation, and component qualification programs.

Own spacecraft assembly, integration, verification, and test campaigns for a Mars orbiter. Develop procedures, test plans, acceptance criteria, tooling, ground support equipment, and campaign infrastructure. Lead thermal, vibration, EMI/EMC, functional, and end-to-end payload testing; conduct readiness reviews, troubleshoot failures, close verification requirements, and maintain configuration and test records through launch. Collaborate across hardware, software, and systems engineering teams while identifying design-for-assembly, access, handling, and testability risks.

Design and develop tooling, fixtures, custom machines, and factory automation equipment for rocket manufacturing. Responsibilities include mechanical design and analysis, drafting to ASME Y14.5 standards, collaboration with design and manufacturing teams, and management of tooling projects from vendor selection through fabrication, inspection, installation, and commissioning. The role requires CAD and FEA experience, manufacturing knowledge, and the ability to deliver full-cycle projects in a fast-paced environment.

Develops and improves machining processes for rocket components, including process plans, SOPs, inspection plans, fixturing, and workholding designs. Advises design teams on manufacturability, GD&T, inspection methods, and datum structures. Investigates nonconforming hardware, identifies root causes, and implements corrective actions. Requires an engineering or STEM degree, extensive machining experience, and manufacturing engineering, quality, or supply chain experience.

Manage end-to-end accounts payable operations, including invoice processing, purchase order matching, payment runs, aging, escalations, and controls. Lead and develop the AP team, monitor performance metrics, resolve vendor and payment issues, collaborate cross-functionally, and improve processes through automation, OCR, and AI-enabled tools. The role requires strong procure-to-pay expertise, ERP and Excel proficiency, and experience managing high-volume AP operations.

Leads materials and process engineering for hybrid aerospace manufacturing. Encodes metallurgy, process windows, material models, and manufacturability constraints into DFM systems. Develops WAAM, directed energy deposition, CNC, and hybrid process guidance; characterizes microstructure, defects, stresses, and properties; and conducts hands-on validation through coupons, testing, heat treatment, NDE, and metallography. Owns qualification plans and design allowables aligned with NAVSEA and MMPDS requirements while collaborating with software, design, production, quality, and suppliers.

Own manufacturing and test integration for rocket mechanisms from design release through vehicle integration. Develop assembly flows, mBOMs, work orders, specifications, tooling, and workcenter processes. Support production floor operations, resolve discrepancies, lead root-cause and corrective actions, improve manufacturability, and mentor manufacturing engineers. The role covers interdisciplinary mechanical, electrical, and pneumatic assemblies for reusable launch vehicle hardware.
