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. AI at Hyliion At Hyliion, AI is core to how we work. We equip every team member with leading AI tools and count on you to use them — to move faster, solve harder problems, and help us realize the full potential of KARNO technology for the world.

About the Role: We are seeking a Senior Staff Machine Learning Engineer to define and accelerate how we leverage agentic AI to transform machine learning models and modeling workflows. This high-impact role focuses directly on modeling leverage —enhancing model quality and velocity—rather than building general infrastructure. As a senior staff engineer, you will operate as a technical leader across the entire modeling loop, utilizing modern AI-assisted development systems (such as Claude, Cursor, and comparable tools) to make model development faster, more rigorous, and significantly more effective across the organization. Why Join Us? This role offers a domain-flexible platform to redefine how ML engineering is done. If you are passionate about combining deep ML fundamentals with the vanguard of agentic AI to multiply team impact, we’d love to talk to you. What you’ll do: Develop advanced ML models and the agentic workflows that help teams design, train, evaluate, and improve them. Use tools such as Claude, Cursor, and comparable AI-assisted development systems to investigate model behavior, generate and test hypotheses, automate repetitive analysis, and improve code and experiments. Build reliable loops for data and label analysis, feature and embedding development, architecture comparison, hyperparameter optimization, error analysis, and experiment readouts. Design evaluation harnesses that measure both model outcomes and agent/workflow quality, including correctness, reproducibility, regressions, cost, a
