Lead a team of analysts in the thermal, structural, and dynamic analysis of integrated design hardware for rocket engines, ensuring design meets reliability and performance standards.

Designs, analyzes, tests, and supports manufacturing of Terran R primary and secondary flight structures. Responsibilities include developing structural load paths, sizing components, reviewing loads and material properties, releasing drawings, supporting hardware test campaigns, evaluating results, and improving manufacturability. The engineer owns designs from requirements through production using CAD and structural analysis tools, collaborates across teams, and leads projects to completion.

Design, analyze, test, and release primary and secondary rocket structures for Relativity Space’s Terran R vehicle. Own components from requirements through production, including load-path conceptualization, structural sizing, CAD modeling, drawing release, hardware test campaigns, and manufacturing process development. Use NX/Teamcenter, Nastran, ANSYS, and hand calculations while collaborating across teams to reduce mass, parts, processes, and tooling.

Leads corporate finance partnership for G&A functions, owning budgets, headcount planning, annual operating plans, quarterly forecasts, reporting, scenario modeling, pricing analysis, and unit economics. Drives monthly business reviews, develops KPIs, explains variances, and improves planning and reporting through Planful automation and dashboards. Provides financial guidance to non-finance leaders and supports ad hoc strategic analyses.

Build and deploy AI-powered applications and agents for engineers and operators across the rocket manufacturing organization. Responsibilities include full-lifecycle software development, foundation-model integration, retrieval and vector search, evaluation, reliability, testing, continuous integration and deployment, and collaboration with users to define and iterate on solutions. The role uses modern AI, data, cloud, and platform technologies in manufacturing and physical-world environments.

Build and deploy AI-powered applications and agents used by engineers and operators. Responsibilities include full-cycle software development, foundation model integration, retrieval and tool use, evaluation, reliability, continuous delivery, and collaboration with non-software stakeholders. The role involves shipping production-quality systems across cloud and on-premise infrastructure while iterating on solutions for rocket manufacturing and launch operations.

Design and develop primary and secondary flight structures and mechanisms for the Terran R rocket from concept through release. Create and release drawings with GD&T, perform packaging and tolerance stack analyses, optimize geometry for mass and manufacturability, support BOM and PLM configuration management, and coordinate closely with manufacturing to validate fabrication and assembly.

As a Staff Structures Engineer, you'll lead spacecraft structures design from concept to flight, ensuring performance and reliability while collaborating across teams.

As a Senior Optical Communications Engineer, you'll design and develop deep-space optical communication terminals, translating mission needs into performance requirements and guiding implementation while leading hands-on development to validate technologies and systems.
