Turbomachinery Engineer

Turbomachinery Designer

A fast-moving launch vehicle company is developing a medium-lift orbital rocket and is looking for a Turbomachinery CAD/GD&T/Stack-up Designer to support the development of a high-thrust liquid rocket engine.

This role owns the translation of preliminary mechanical designs into release-ready hardware definition, including 3D models, 2D drawings, GD&T schemes, tolerance stack-ups, and production documentation for pumps, turbines, housings, impellers, shafts, seals, bearings, manifolds, volutes, and related rotating assemblies.

You will work across design, analysis, manufacturing, quality, suppliers, and internal build teams to make sure hardware is manufacturable, inspectable, and configuration-controlled.

Responsibilities

Own detailed 3D CAD models and assemblies for turbopump and rotating hardware.

Create production-ready 2D drawings covering datums, GD&T, surface finish, heat treatment, coatings, inspection requirements, and manufacturing notes.

Run tolerance stack-ups and define fits, clearances, and interface controls for cryogenic, hot-side, and transient operating environments.

Challenge design intent where needed, identifying costly or risky features and proposing manufacturable alternatives.

Support CNC, additive, EDM, grinding, balancing, brazing, welding, and related manufacturing processes.

Drive parts through PLM release, including part numbering, revisions, EBOM structure, and ECO documentation.

Work with suppliers and internal teams on RFIs, first-article inspection, CMM plans, metrology strategy, and nonconformance reviews.

Own drafting standards, templates, checking routines, title blocks, and drawing review practices.

Act as a GD&T focal point during design reviews.

Required Experience

Technical degree in mechanical design, product design, industrial drafting, or equivalent practical experience.

9+ years releasing detailed drawings for precision mechanical hardware in aerospace, turbomachinery, motorsport, energy, or another regulated/high-performance industry.

Hands-on experience with turbopump hardware through manufacturing and testing, including cold-flow, spin, or hot-fire campaigns.

Advanced CAD capability, ideally Siemens NX.

Strong ISO GPS / GD&T knowledge and datum strategy experience.

Proven ability to run tolerance stack-ups and define fits, clearances, runout, concentricity, and inspection criteria.

Ability to interpret FEA, rotordynamics, and manufacturing tolerance studies into drawing requirements.

Practical understanding of CNC turning/milling, additive manufacturing, EDM, grinding, and DfM/DfA trade-offs.

Experience with PLM/PDM systems, preferably Teamcenter.

Comfort operating in a high-ownership environment where process is still being built.

Preferred Experience

Formal GD&T, ISO GPS, metrology, or drafting certification.

Experience detailing rotating equipment or high-precision mechanical hardware.

Direct exposure to CMM, first-article inspection, GD&T verification, and nonconformance review.

Knowledge of bearing and seal fits, balance-driven requirements, surface finishes, coatings, heat treatments, cryogenic hardware, or hot-section turbomachinery.

Experience with aerospace configuration control and traceability for flight or test hardware.

Experience producing assembly drawings, exploded views, and shop-floor integration or test instructions.
