Job description

Lead Design Engineer – Round-Peg Solutions (RPS)

Do you want to design products that are the industry standard and truly “go-to” solutions?

Are you looking for a hands-on design role where you own products end-to-end, not just incremental changes?

Would you value the feel of a close-knit, family-style engineering team, backed by the stability and resources of a multi-billion-dollar global brand?

This well-established and trusted organization is continuing to invest in its engineering capability and is seeking a Lead Design Engineer to join the team in Newton, NH. The business designs new products every year, while continuously improving an existing, highly respected product portfolio used across the industry.

This role is design-led, focused on large mechanical systems, structural components, and hydraulic-driven equipment, offering both technical ownership and long-term career growth.

• Lead the mechanical design of new and existing heavy equipment and large machinery systems, including structural assemblies and hydraulic mechanisms
• Own the full product lifecycle — from concept, calculations, layouts, and 3D modeling through to detailed drawings and manufacturing release
• Create and maintain robust manufacturing design packages, including GD&T, tolerances, and Engineering BOMs, ensuring designs are production-ready
• Drive design improvements through root-cause analysis of field, quality, or performance issues, implementing effective corrective actions
• Collaborate closely with fabrication, machining, welding, and assembly teams, while mentoring engineers and helping set design standards

Lead Design Engineer Qualifications

• 5+ years of mechanical design experience
• (heavy equipment, industrial machinery, or large engineered systems preferred)
• Strong proficiency in SolidWorks and/or Inventor
• Good understanding of how designs translate into manufacturable products, applying DFM principles, ideally with experience designing components and assemblies intended for welded fabrication
• Bachelor’s degree in Mechanical Engineering or a related discipline preferred

Why Join as a Lead Design Engineer?

This is an opportunity to join a sub-100-person, family-culture engineering team where your work has real visibility and impact — while still benefiting from the backing, stability, and growth of a global, multi-billion-dollar organization. The company is growing year-on-year, investing in innovation, and offers group-wide career opportunities for those looking to progress technically or into broader leadership roles.

Apply now and suitable candidates will be contacted within 24 hours.
