Develops machining process plans, SOPs, inspection plans, and fixturing designs for aerospace components. Improves manufacturing processes, advises on design for manufacturability, defines inspection and GD&T requirements, and investigates nonconforming hardware to identify root causes and corrective actions. Collaborates with engineering and design teams to improve part designs, manufacturing methods, and production quality.

Develops and validates thermal systems for Terran R launch vehicles, including insulation, heaters, thermal protection, and environmental conditioning. Performs component, subsystem, and vehicle-level thermal analyses; supports tool development, automation, testing, instrumentation, data processing, stage testing, and flight operations. Collaborates with design and hardware engineering teams to resolve thermal challenges and meet system requirements.

Facilitates new-hire orientation, leadership development, and internal training across virtual, in-person, and hybrid formats. Supports program managers with scheduling, attendance tracking, materials, communications, documentation, vendor coordination, and stakeholder collaboration. Assists with internal events, facility tours, and speaking engagements while adapting delivery to varied audiences and learning styles.

Designs, analyzes, tests, and supports manufacturing of primary and secondary rocket structures for Relativity Space’s Terran R vehicle. Responsibilities include developing structural load paths, sizing flight hardware, reviewing loads and material properties, releasing drawings, supporting hardware test campaigns, and owning components from requirements through production using CAD and structural-analysis tools.

Develops and owns nondestructive evaluation methods for additively manufactured rocket hardware. The role covers feasibility studies, probability-of-detection and qualification plans, drawing requirements, inspection process improvement, and cross-functional integration with additive manufacturing, materials, machining, supply chain, factory automation, and leadership teams.

Owns reliability and quality processes across rocket design, manufacturing, testing, and launch operations. Responsibilities include design standardization, DFM, configuration control, work instruction reviews, in-process build verification, nonconformance management, as-built verification, root-cause analysis, corrective actions, inspection initiatives, and process development. The role collaborates closely with engineering, additive manufacturing, production, test, and launch teams to establish scalable quality systems for the Terran R launch vehicle.

Performs engineering trade studies and analysis for Terran R flight performance, develops and maintains simulation and analysis software, and collaborates cross-functionally across Vehicle Engineering. The role involves launch vehicle and space systems analysis, trajectory design and optimization, communicating technical recommendations, and improving software tooling using languages such as Python, Julia, Rust, and C++.

Lead the end-to-end engineering of a wideband UHF radar sounder and radiometer for a Mars orbiter. Own system design, performance and power budgets, waveform and signal-processing implementations, hardware development, calibration, testing, spacecraft integration, licensing, and commissioning. Coordinate RF, digital, power, mechanical, firmware, software, and science teams while personally executing design and analysis.
