We're looking for a Lead Mechanical Design Engineer eager to take on advanced engineering challenges and contribute directly to the evolution of next-generation reciprocating engines. If you excel in hands-on design, enjoy solving complex mechanical issues, and take pride in leading and mentoring technical teams, this role offers the impact and ownership you're looking for.

As a Lead Mechanical Design Engineer, you'll serve as a technical expert responsible for end-to-end ownership of engine component and system design. You'll lead critical design efforts, own major components and systems, and collaborate across engineering, manufacturing, supply chain, and global partners. In this role, you will:

• Lead and Deliver High-Impact Designs
• Own the design and development of new engine components, systems, and product improvements.
• Define system and component technical requirements while working with cross-functional engineering teams.
• Lead the 3D/2D design of large castings, forgings, machined components, and fabrications, including full GD&T definition and ECO release.

• Drive Engineering Excellence
• Perform engineering calculations, studies, and analysis to support both virtual and physical validation.
• Lead design reviews, cross-functional development teams, and support prototype hardware builds from concept through serial release.
• Guide continuous improvement of design practices, standards, tools, and methodologies.

• Collaborate Across the Business
• Provide technical expertise to manufacturing, supply chain, application engineering, service, marketing, and suppliers.
• Support new product introductions (NPI), current product improvements, and root-cause problem solving across the organization.

What You'll Bring

• Bachelor's or Master's degree in Mechanical Engineering, Engineering Technology, or Mechanical Design Technology.
• More than 6 years of mechanical design engineering experience—preferably with engine components, reciprocating internal combustion engines, or engine-driven equipment.
• Strong proficiency in CREO, high-end 3D CAD, Windchill PLM, and Oracle ERP systems or similar systems.

What Will Help You Stand Out

• Deep knowledge of GD&T, tolerance stack-ups, and precision mechanical design.
• Experience with engine performance, FEA, simulation, testing, and mechanical development.
• Strong understanding of materials, manufacturing processes, and assembly methods.
• Hands-on experience with rapid prototyping, product validation, and design for manufacturability.
• Proven success in NPI leadership or current product support engineering.
• Excellent communication skills and comfort working in a global environment.
• Ability to manage multiple projects with strong organizational and technical writing skills.
