About The Position

The Senior Systems Engineer is a key technical leader responsible for the high-level architectural design of the full KARNO generator system’s mechanical, electrical, and fluid hardware, ensuring it satisfies customer and product requirements from concept through delivery. This role owns the translation of customer and product manager inputs into detailed technical requirements and leads the engineering and validation testing effort needed to prove the system out. Working across mechanical, electrical, thermal, and fluid systems disciplines, the Senior Systems Engineer partners closely with project management, production, and manufacturing teams to keep the product on schedule, while also providing technical mentorship to less experienced members of the engineering team, with the ability to step into hands-on design work directly when needed. This role advances KARNO’s development through disciplined systems thinking, clear requirements ownership, and strong cross-functional leadership. 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.

Requirements

Bachelor’s degree in Mechanical Engineering, Electrical Engineering, or related field
5+ years of experience designing mechanical, electrical, or fluid system components for aerospace, automotive, industrial equipment, or similar applications, with demonstrated experience carrying designs beyond laboratory validation into fielded operation; experience with components deployed and operating in field environments is strongly preferred
Demonstrated experience resolving competing physical design trade-offs across mechanical, electrical, or fluid subsystems on a complex hardware product
Experience serving as a component design owner, with responsibility spanning the full component lifecycle including design, manufacturing quality (e.g., non-conformance disposition), and field support
Basic foundation in mechanical, electrical, thermal, and controls engineering — whether from a formal engineering degree or equivalent practical experience — combined with strong systems-level thinking across mechanical, electrical, thermal, and fluid disciplines
Ability to translate customer and product requirements into detailed technical specifications, grounded in direct experience owning and trading physical hardware constraints
Proficiency with MATLAB, Python, Excel, or similar tools for system modeling to support architecture trade studies and to correlate models against test data
Ability to support project management, production, and manufacturing teams to keep programs on schedule
Demonstrated ability to mentor and provide technical leadership to junior engineers, supported by sufficient hands-on design experience to assume execution responsibilities directly when program needs require it
Experience contributing to the planning, design, construction, and execution of engineering tests, with prior exposure to laboratory test equipment; extensive test experience is not required, but some direct exposure is expected
Strong problem-solving and troubleshooting skills across subsystems and disciplines
Clear and concise technical communication, both written and verbal
Experience with a 3D CAD package such as NX, Creo, SolidWorks, or similar; this role requires performing system assembly layout directly in 3D CAD
