About the role

Hyliion is committed to creating innovative solutions that enable clean, flexible and affordable electricity production.
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.
Why This Role Matters: The KARNO generator relies heavily on advanced materials capable of withstanding extreme loads.

Lead the evaluation and down-selection of high-temperature alloys, stainless steels, ceramics, coatings, and composites for critical KARNO components.
Verify that process changes, maintain material integrity and meet downstream performance demands.
Translate findings into improved designs, tighter process controls, or updated material specifications.
Drive R&D efforts for next-generation materials suitable for high-efficiency distributed power generation.
Collaborate with design, thermal, combustion, and mechanical teams to create data-driven material strategies.
Additive Manufacturing Support
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.
This Advanced Materials Science Engineer supports the materials backbone of the KARNO Power Module, developing, testing, and qualifying the advanced metallic alloys that keep the system running cleanly and efficiently.
You'll dive into how these materials behave under extreme heat, high loads, and rapid cycling, then turn that insight into practical design guidance, additive manufacturing parameters, and durability improvements that directly influence engine performance.
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.

Ability to lift and/or move up to 50 pounds.
Ability to travel domestically, as needed, by plane, automobile, etc. approximately 30% of the time,
Bachelor's in metallurgical engineering or materials science degree required
5+ years working with metals and materials characterization (graduate research counts).
Reasonable accommodation may be made to enable individuals with disabilities to perform the essential functions.
Education, Experience and Certifications
Strong background in material behaviors such as fatigue, creep, oxidation, and thermal-mechanical degradation.
Skills and Abilities

Experience supporting additive manufacturing materials or metal powder evaluation is strongly preferred.

Hands-on experience with mechanical testing, microstructural evaluation, and failure analysis.
Understanding of how material change with heat treatment, AM process changes, or post-processing steps.
Familiarity with high-temperature alloys, surface treatments, coatings, and joining methods.
Ability to evaluate metal integrity when parameters or processes shift.
Strong analytical and problem-solving ability.
Clear, concise technical communication.
Comfortable working across disciplines (AM, thermal, mechanical, combustion, suppliers).
Detail-oriented with a research-driven mindset.
