The group you’ll be a part of
This position is part of the Supplier Engineering and Technology (SET) organization, which advances manufacturing technology, materials, and supply chain capability.
The impact you’ll make
As a Supplier Engineer, you will play a critical role in developing and managing suppliers of complex metal components and assemblies, with primary focus on semiconductor showerheads and pedestals.
You will work cross-functionally with product engineering, design engineering, quality, operations, and suppliers to resolve technical, quality, and production challenges. The role requires strong hands-on knowledge of fabrication, precision machining, joining, assembly, metallurgy, metrology, and process control for high-complexity metal parts.
The ideal candidate is a results-driven self-starter with strong technical judgment, structured problem-solving skills, and a customer-focused mindset. This individual must be able to manage multiple priorities in a fast-paced environment and work effectively both independently and across global teams.

- Work with supplier to design engineering to provide Design for Manufacturability, Assembly, and Cost input for showerheads, pedestals, and related components.
- Provide technical expertise for complex metal components and assemblies, including precision CNC machining, milling, turning, drilling, grinding, and specialty finishing processes.
- Provide expertise in metal joining and assembly processes, including aluminum brazing, vacuum brazing, welding, diffusion bonding, mechanical fastening, sealing interfaces, etc. as applicable.
- Assess product drawings, specifications, tolerances, GD&T, material requirements, inspection and assembly interfaces to ensure supplier processes can repeatedly meet design intent.
- Develop, qualify, and improve supplier manufacturing process flows for complex metal parts and assemblies, from raw material through machining, joining, cleaning, inspection, and final assembly.
- Work with supplier to identify and control critical process inputs and outputs, special processes, and process-of-record requirements that affect product performance, reliability, and yield.
- Lead technical reviews of tooling, fixturing, joining parameters, machining strategy, thermal distortion, flatness, hole pattern capability, surface finish, dimensional stack-up, and assembly alignment
- Develop, document, and execute qualification plans, including first article inspection, capability studies, destructive and nondestructive evaluation, leak testing, dimensional inspection, and functional validation.
- Lead root cause and corrective action for quality and supplier technical issues using structured problem-solving methods. Translate failure evidence into containment, corrective action, and prevention.
- Drive supplier improvements in quality, manufacturability, cost, and capacity while maintaining product requirements.
- Audits suppliers on site focused on manufacturing controls, special processes, inspection systems, quality management systems, and adherence to approved process of record (POR).Develop Best Known Methods, control plans, inspection strategies, and supplier quality scorecards to improve repeatability and reduce variation.
- Lead high-visibility technical projects and remain accountable for scope, milestones, risks, decisions, and closure.
- Evaluate new fabrication, joining, inspection, and automation technologies that can improve product performance, capability, or manufacturing robustness.
Who we’re looking for
- Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, Materials Science and Engineering, Welding Engineering, Metallurgical Engineering, or a related technical field from an accredited university is required.
