Day-to-day, you'll work closely with the KARNO engineering teams - mechanical, thermal, design, and additive - to evaluate new alloys, validate new processes, and help build Hyliion's internal additive materials program from the ground up. If you're energized by pushing high-temperature metals to their limits and shaping how next-generation power hardware is engineered, you'll have a big impact here. Duties and Responsibilities: Material Selection, Qualification & Behavior Lead the evaluation and down-selection of high-temperature alloys, stainless steels, ceramics, coatings, and composites for critical KARNO components. Define material requirements based on thermal, mechanical, oxidation, and fatigue loads. Conduct microstructural and mechanical characterization to confirm performance against lifecycle and durability targets. Testing, Characterization & Analysis Plan and execute material tests including tensile, creep, fatigue, thermal cycling, hardness, and corrosion/oxidation evaluations.
