Develop engine systems (valvetrain, pistons, connecting rods, balance systems, bearings, etc.) from concept selection to production.
Advise in developing new engine architecture for naturally aspirated, super charged, or turbo charged spark ignited engines
Provide guidance on system layout and component selection (bore-stroke, layout, valve train type, piston sizing, crank train layout, timing drive)
Work with component engineers, suppliers, and the analysis group to verify component designs meet system requirements.
Develop component & system level DFMEAs and Design Validation Plans (DVPs). Then, using the test plan identified, execute the required testing and document results.
Design cost-effective experiments to prove proposed concepts and reduce technical risk.
Challenge legacy solutions and introduce innovative, manufacturable designs.
Generate patentable ideas leading to commercial success.
Provide engineering recommendations on system-level tradeoffs involving performance, durability, NVH, weight, cost, and manufacturability.
Participate in design reviews, issue resolution, and root-cause investigations crossing component boundaries.
Mentor and technically guide team members.
Help define and reinforce engine development best practices and internal technical standards.
Diversity of thought and experiences is fundamental when imagining the unimaginable. Certain skillsets/experiences are necessary; however, others can be developed along the way.
Required Qualifications:
Bachelor’s degree in Mechanical Engineering or equivalent.
8 years of progressive experience in internal combustion engines.
Demonstrated ownership of engine component or mechanical systems development.
Broad understanding of overall engine system interactions.
Proven ability to define and execute comprehensive DVPs.

Recognized technical leader within prior organizations.
Strong understanding of engine related manufacturing processes including casting, forging, machining, injection molding, heat treatment, grinding, balancing, and assembly.
