About the role

Senior tooling designer responsible for wax injection molds and ceramic core injection molds for turbine blades and vanes, supporting high-rate production and tight tolerances in investment casting.

Responsibilities

  • Design high-precision wax injection molds and ceramic core injection molds for complex turbine blades and vanes to be manufactured in-house
  • Interpret and enable mold filling simulations and apply first-principles analysis to optimize gating, venting, cooling, and shrinkage compensation
  • Account for multi-stage shrinkage (wax, ceramic, and alloy) to consistently meet stringent dimensional and metallurgical requirements
  • Own tooling designs from concept through tryout, qualification, and production release
  • Own and manage the feasibility and surfacing of critical mold components
  • Collaborate closely casting engineers, materials scientists, and vendors to troubleshoot tooling-related casting defects and improve yield
  • Apply advanced GD&T and tolerance stack-up analysis to complex airfoil geometries
  • Support design for manufacturability (DFM) initiatives to enable high-rate production while maintaining quality and cost targets
  • Interface with internal manufacturing teams and external tooling vendors to ensure designs are successfully translated into reliable production tooling
  • Drive continuous improvement of tooling standards, materials, and maintenance practices for high-volume casting operations

Qualifications

  • 5+ years of professional experience designing high-precision injection molds for wax patterns AND ceramics
  • 3+ years of feasibility for wax patterns AND ceramics
  • Experience with Siemens NX
