Job summary

Radiant Industries in El Segundo, CA seeks a Staff Turbomachinery Engineer to own the turbomachinery mechanical system for a 1MW Brayton-cycle power system. You will drive rotor dynamics, structural analysis, and integration with electrical and thermal teams to deliver production-ready hardware.

This high-ownership role requires deep expertise in high-speed rotating machinery, tolerance stack-ups, and proven design-through-testing experience in a fast-paced, first-of-a-kind development

Qualifications

• B.S. in Mechanical Engineering or related field.
• 8+ years designing high-speed rotating machinery (turbines, compressors, or similar).
• Deep expertise in structural analysis and mechanical design of turbomachinery.
• Experience with bearings, seals, and high-speed shafting design.
• Expert-level proficiency with analysis tools (e.g., ANSYS) and advanced use of NX and Teamcenter for complex design, simulation, and PLM.
• Strong understanding of tolerancing, GD&T, and precision mechanical assembly.
• Experience owning hardware through design, build, and test cycles.
• Hands-on experience with assembly, integration, and troubleshooting of turbomachinery.

Responsibilities

• Own turbomachinery mechanical system as Responsible Engineer.
• Define mechanical architecture for high-speed rotating assemblies (up to ~30 krpm).
• Lead rotor dynamics, structural integrity, and life analysis for rotating components.
• Flow down requirements from system-level constraints (thermal, structural, environmental).
• Decide rotor layout, shafting, bearings, seals, materials, and clearances.
• Ensure designs meet performance, reliability, safety, and regulatory requirements.
• Collaborate with turbomachinery aero, motor design, thermal, manufacturing and test teams.
