About The Position

Doncasters is seeking a Wax Process Engineer to serve as the primary technical authority for the entire wax pattern and wax mold assembly preparation value stream. This role is located on-site at their Oxford, Alabama, aerospace investment casting facility. The engineer will own process stability, wax injection parameters, and assembly standards for high-integrity wax assemblies. Their responsibilities will cover the receipt and quality validation of ceramic cores, wax injection for patterns and ancillary components, final mold setup, and preparation for shell loading. This role is crucial for downstream casting quality, focusing on dimensional repeatability, minimizing inclusion defects, eliminating assembly-induced stress, and maintaining strict fixed process controls for turbine blades and vanes.

Requirements

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Manufacturing Engineering, Chemical Engineering or related engineering discipline from an accredited program.
• Minimum 3 years of engineering experience in an industrial manufacturing environment.
• Explicit experience in injection molding or investment casting wax room operations.
