Job Description:

We are seeking a Turbomachinery Manufacturing Engineer to own the build process for the rotating equipment at the core of our supercritical CO₂ systems — from rotor assembly through balancing, clearance checks, and final proof. We are a team that values first-principles thinking, hands-on problem solving, and close cross-functional collaboration to deliver cohesive, high-performance systems.

Responsibilities:

• Own manufacturing and assembly processes for rotating hardware: rotor balancing, interference fits, clearance checks, structural proofing, and leak checks

• Develop and refine fabrication, assembly, and test procedures for turbopump/compressor subassemblies

• Partner directly with design engineering to resolve manufacturability issues on high-speed rotating components

• Design and specify assembly tooling — from concept through detailed drawings and analysis

• Serve as a main point of contact between design and manufacturing as we optimize turbomachinery architecture and scale operations

• Drive root cause investigations on assembly or test failures and implement fixes that hold up at rate

Required Qualifications:

• Degree in Mechanical Engineering or related technical field, 5+ years relevant experience

• Direct experience with turbomachinery or rotating equipment assembly procedures, including rotor balancing, interference fits, clearance checks, structural proofing, and leak checks

• Experience with tolerance stack-up analysis, structural proof testing, and pressurized leak checks

• Experience with tooling design, including conceptualization, modeling and drafting, and detailed analysis

Preferred Qualifications:

• Experience with cryogenic or supercritical fluid systems

• Proficiency in Siemens NX or other CAD

• Knowledge of GD&T (ASME Y14.5) and industry specifications

• Experience in a startup or agile development environment

• Background in a flight-hardware or high-reliability development program

Role level to be determined during interview process
