Senior Supplier Quality Engineer

• ◆Serve as the engineering authority for machined commodities, including turning, milling, grinding, honing and lapping, EDM, balancing, deburring and edge condition, and associated special processes including heat treat, coating, plating, and NDT.
• ◆Assess and develop the machining supply base, including process capability studies, machine and fixture capability, tooling strategy, workholding for distortion-prone geometry, and capacity readiness for planned rate increases. Conduct process-based audits rather than checklist audits.
• ◆Own first article inspection and part qualification, including AS9102-style FAI, dimensional layout, key characteristic definition, and a PPAP-style evidence set scaled to a low-volume, high-consequence environment.
• ◆Review drawings before release to RFQ, challenging datum schemes that cannot be fixtured, tolerances no process can hold, surface finish callouts without a functional basis, and inspection

no gage can verify.

• ✓Build inspection and acceptance strategy, including inspection plans, key characteristics, sampling versus 100% inspection, source inspection and delegation decisions, certificates of conformance, material certification, and traceability.
• ✓Own measurement agreement between suppliers and Hyliion metrology, including CMM programming and fixturing, form and roundness measurement, surface profilometry, air gaging, and gage R&R and MSA studies, and resolve measurement disagreement at its source.
• ✓Lead containment, root cause, and corrective action with suppliers using 8D and structured problem solving, driving to a process condition as root cause, verifying fixes with data, and analyzing escapes to determine why the internal acceptance system did not catch them.
• ✓Assess the impact of engineering changes on supplier tooling, fixturing, programs, and inspection before release, and make the cost of late change visible to internal decision makers.
• ✓Build and run the supplier quality system, including conformance tracking, scorecards, risk-proportionate surveillance plans, quality agreements, and approved supplier status.
• ✓Own the interface where additively manufactured components meet finish machining, including datum establishment on as-built surfaces, stock allowance, fixturing of thin-wall and distortion-prone geometry, witness surfaces, and verification of internal features.
• ✓Represent supplier constraints and capability inside Hyliion with the same rigor applied to representing Hyliion

to suppliers, and escalate internal failures to the same evidence standard as supplier failures.

• ✓Hold internal functions accountable for the inputs suppliers depend on, including releasable and unambiguous drawings and timely disposition of supplier questions and deviations from Product Engineering, defined and consistently communicated inspection methods and acceptance criteria from Quality, realistic lead times and clean purchase orders from Supply Chain, and downstream feedback on delivered parts from Operations.
• ✓Set the technical standard for supplier quality on machined content, including mentoring engineers, technicians, and inspectors, guiding judgment calls on borderline parts, and representing Hyliion technically in supplier management reviews.
• ✓Additional duties and

as assigned, needed, or required for the business.
