Turbomachinery Designer

About the roleCanada Rocket Company is building the turbomachinery that drives our 750 kN engine. We’re looking for a Turbomachinery CAD/GD&T/Stack-up Designer to take preliminary designs from our mechanical engineers and turn them into release-ready hardware definition. You’ll own the 3D models, 2D drawings, GD&T schemes, and stack-ups for pumps, turbines, and the rotating assemblies that operate at the limit of what materials and manufacturing can deliver.
This is a hands‑on, high‑ownership seat. You’ll sit between design, analysis, manufacturing, quality, and our supply base deciding what the drawing actually says, what gets toleranced where, and how the part will be inspected when it lands at the dock. At most companies, drafting is a downstream function. Here, your drawings are the contract between design intent and the hardware that ends up on the test stand.
What you’ll do
Build and maintain detailed 3D CAD models and full assemblies for turbopump hardware: pumps, turbines, housings, impellers, shafts, seals, bearings, manifolds, and the volutes and ducting that tie them together.
Author and release production 2D drawings end‑to‑end datums, GD&T per ISO GPS, surface finish, heat treatment, coatings, and inspection callouts at a level that lets a machine shop quote and cut without a back‑and‑forth.
Run tolerance stack‑ups and define the fits, clearances, and interface controls that keep rotating assemblies functional through cryogenic startup, hot‑side operation, and thermal transients.
Push back on design intent where it makes sense: flag features that are expensive, slow, or risky to manufacture, and propose CAD changes that pull cost and lead time out of the part. Cover the full process spread CNC, additive, EDM, grinding, balancing, brazing/welding.
Drive parts through the PLM release cycle (Teamcenter or equivalent): part numbering, revisions, EBOM structure, and ECO documentation, so configuration is never in doubt.
Work directly with suppliers and our internal shop on RFIs, first‑article inspection, CMM and metrology plans, and nonconformity dispositioning. The drawing must be inspectable, not just drawable.
Own the drafting standard: templates, checking routines, title blocks, and review practice. Be the GD&T focal in design reviews and hold the line on drawing quality across the program.
QualificationsRequired
Technical degree in mechanical design, product design, industrial drafting, or equivalent practical background. A formal engineering degree is not required, demonstrated drafting depth is.
9+ years releasing detailed drawings for precision mechanical hardware in aerospace, turbomachinery, motorsport, energy, or another high‑performance or regulated industry.
Direct hands‑on experience manufacturing and testing turbopump hardware time on the shop floor during builds and on the stand during cold‑flow, spin, or hot‑fire campaigns. You’ve seen how your drawings hold up when the parts come back from the vendor and when the assembly gets torn down post‑test.
Advanced CAD proficiency, ideally Siemens NX, with real fluency in detail design, large assemblies, and drawing generation.
Deep working knowledge of ISO GPS / GD&T and datum strategy, with a track record of producing drawings that inspectors and machinists don’t need to interpret.
Comfort running tolerance stack‑ups, defining fits and clearances, and managing the interfaces that determine whether an assembly works.
Ability to ingest analysis outputs FEA on rotor and stator assemblies, rotordynamic results, manufacturing tolerance studies and translate them into concrete drawing requirements: datum strategy, GD&T callouts, fits, runout and concentricity targets, and inspection criteria.
Practical understanding of how parts get made CNC turning and milling, additive, EDM, grinding and how DfM/DfA decisions ripple through cost, schedule, and yield.
Working command of PLM/PDM (Teamcenter preferred): revision control, release workflows, and engineering change.
Comfortable building process where it doesn’t exist yet.
Preferred
Formal GD&T / ISO GPS, metrology, or drafting certification.
Hands‑on experience detailing rotating equipment or high‑precision hardware and embedded with machine shops and inspectors during the build.
Direct experience with CMM and metrology workflows: GD&T verification, first‑article inspection, and nonconformity review.
Working knowledge of bearing and seal fits, runout and concentricity targets, and balance‑driven drawing requirements.
Familiarity with the materials, heat treatments, coatings, and surface finishes used on cryogenic and hot‑section turbomachinery.
Prior exposure to aerospace configuration control and traceability for flight or test hardware.
Experience producing assembly drawings, exploded views, and integration/test work instructions used on the floor.
