Senior Supplier Quality Engineer

The posting, as Hyliion wrote it

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production. The Company’s primary focus is to develop distributed power generators that can operate on various fuel sources to future-proof against an ever-changing energy economy.

Job Purpose

The Senior Supplier Quality Engineer owns the technical health of Hyliion's precision machining supply base and serves as the senior technical authority for machined content on the KARNO Power Module. Much of the machined content that determines whether a machine runs, including tolerances, surface finishes, form and runout requirements, and sealing surfaces, is produced by external partners, some of it on additively manufactured parts. This position sets the standard for how supplier quality is practiced at Hyliion, including the qualification evidence required, the inspection methods used, and the technical judgment applied when a part is borderline. The role works in both directions: outward, building engineering-grade partnership with machining suppliers and closing the gap between what drawings require and what supplier processes can repeatably deliver; and inward, holding Product Engineering, Quality, Supply Chain, and Operations accountable for releasable drawings, defined acceptance criteria, realistic schedules, and closed feedback loops. The position carries no authority over those functions and operates through technical credibility and evidence.

Duties and Responsibilities

• 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 requirements 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.
