About Tech Castings:
Tech Castings is a leader in Aerospace Investment Casting with a steadfast commitment to investing in the best business tools and equipment available. We have grown revenue in every year of our existence since 2011, working with OEM’s including GE Aerospace, Rolls Royce and Honeywell, and recently completed a 5-million-dollar expansion.
Position Summary
The Investment Casting Process Engineer supports the development, optimization, and sustainment of manufacturing processes for precision aerospace components produced via the investment casting method. Working closely with senior engineers and production leadership, this role focuses on process stability, casting quality, and continuous improvement across wax, shell, vacuum and air casting, and finishing operations with a primary emphasis on nickel and cobalt-based superalloy systems.
Key Responsibilities
Process Support & Optimization
Support development and validation of casting processes for new and existing aerospace components, including gating/riser design, shell system parameters, and vacuum melt/pour parameters
Maintain and update process control plans, work instructions, and inspection criteria
Assist in root cause analysis and corrective action for casting defects common to superalloy systems shrinkage porosity, hot tearing, grain defects, ceramic inclusion, and surface oxidation
Track and analyze scrap and rework data to identify yield improvement opportunities
Technical & Production Support
Provide engineering support to wax, shell, vacuum furnace, and finishing operations on a day-to-day basis
Troubleshoot process deviations related to dimensional non-conformance, surface finish, and metallurgical properties
Interface with metallurgical lab for chemistry verification, microstructure review, and mechanical property evaluation (tensile, stress rupture, hardness)
Support fluorescent penetrant inspection (FPI) and X-ray review processes
New Product Introduction (NPI)
Participate in design-for-manufacturability (DFM) reviews for new aerospace castings
Assist in quoting new parts for customers including cost estimating, specification review, gating design, and tooling requirements
Assist in developing tooling specifications and coordinating wax die design, build, and qualification with tooling suppliers
Support first article inspection (FAI) and AS9102 documentation packages
Quality & Compliance
Support NADCAP and AS9100 audit preparation and surveillance activities
Maintain familiarity with customer-specific requirements and aerospace material specifications (AMS, PWA, GE, Rolls-Royce, etc.)
Assist with SPC implementation and control chart monitoring for critical casting parameters
Continuous Improvement
Participate in Lean and Kaizen events within the foundry
Contribute to PFMEA updates and process risk reviews
Collaborate with maintenance on PM programs for vacuum induction melting (VIM) furnaces, autoclaves, and shell room equipment
Requirements:
Qualifications
Required
Bachelor's degree in Materials Science, Metallurgical Engineering, Mechanical Engineering, or related field
1–4 years of experience in investment casting, precision casting, or aerospace manufacturing (internship or co-op experience in a foundry environment considered)
Basic understanding of superalloy metallurgy (nickel- and cobalt-based alloys, solidification behavior, oxidation resistance)
Familiarity with GD&T and CMM-based and/or laser dimensional inspection
Familiarity with casting and machining blueprints
Capability in 3D drawing, component design, and model editing (i.e. SolidWorks)
Strong analytical and problem-solving skills
Preferred
Hands-on experience with vacuum induction and air melting operations
Basic understanding of superalloy metallurgy (nickel- and cobalt-based alloys, solidification behavior, oxidation resistance)
Familiarity with ceramic shell systems used in superalloy casting (zircon face coats, alumina/silica backup systems)
Exposure to NADCAP or AS9100 quality environments
Six Sigma Green Belt or coursework toward certification
Work Environment
This position operates in both office and active foundry settings. Regular exposure to vacuum furnace operations, high-temperature environments, ceramic particulate, and chemical shell materials is expected. Full PPE compliance is required. Occasional travel to customer facilities or suppliers may be required.
Competencies
Detail-oriented with solid organizational and documentation habits
Eagerness to develop deep technical expertise in superalloy casting
Collaborative mindset with ability to work across engineering, quality, and production teams
Ability to communicate technical findings clearly to both engineers and operators
