Principal Engineer - Mechanical Development

Join Brunswick, a global marine leader committed to advancing marine technology. We seek a Mechanical Development Principal Engineer to lead engine system design and development, providing technical guidance across all engine components.

As a Mechanical Development Principal Engineer, you will serve as a senior technical authority within Mercury’s product development organization. This role combines direct ownership of assigned engine systems with a broader responsibility to provide system-level guidance, technical judgment, and engineering recommendations across all engine development efforts.

• Design and develop engine systems, including valve train, pistons, connecting rods, balance systems, and bearings, from concept through production.
• Advise on 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).
• Collaborate with component engineers, suppliers, and the analysis group to verify component designs meet system requirements.
• Develop component and system level DFMEAs and Design Validation Plans; execute required testing and document results.
• Design cost‑effective experiments to validate concepts and reduce technical risk.
• Challenge legacy solutions and introduce innovative, manufacturable designs.
• Generate patentable ideas that support commercial success.
• Represent system‑level tradeoffs involving performance, durability, NVH, weight, cost, and manufacturability.
• Participate in design reviews, issue resolution, and root‑cause investigations across component boundaries.
• Mentor and technically guide team members.
• Help define and reinforce best practices and internal technical standards for engine development.

• Bachelor’s degree in Mechanical Engineering or equivalent.
• Eight or more 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 Design Validation Plans.

• Master’s degree in Mechanical Engineering or related field.
• Proficiency with Creo or ProE.
• Experience applying DFSS tools.
• Recognized technical leader in prior organizations.
• Strong understanding of engine‑related manufacturing processes, including casting, forging, machining, injection molding, heat treatment, grinding, balancing, and assembly.

Salary range: $103,200 - $164,500 annually. Base pay depends on qualifications, experience, business needs, and location. Additional compensation includes an annual discretionary bonus and eligibility to participate in Brunswick’s benefits program, including medical, dental, vision, paid vacation, 401 k with up to 4% match, Health Savings Account with company contribution, well‑being program, and product purchase discounts.
