Principal Molding Engineer
- Southeast Michigan Precision components.
Real ownership. High-impact hire. This manufacturer is expanding rapidly within a high-growth segment of the medical technology market, supporting next-generation surgical systems. As they scale, they are investing heavily in their plastics and molding capabilities, with a growing focus on overmolding and precision injection molding , alongside micro-scale components. They are looking for a hands-on molding engineer who can help elevate their technical capabilities and play a key role in how their plastics operation evolves. Why this role matters right now The business is at an inflection point. Historically strong in other manufacturing areas, they are now actively building out their plastics expertise and bringing more work in-house. A major part of that growth is expanding their overmolding capability , and they need someone who understands how to develop, troubleshoot, and scale those processes in a production environment. They are looking for a true plastics/process SME who can step in and help guide process development, tooling decisions, and how molding is approached moving forward. This is a smaller, collaborative team where engineers have real influence. The culture is consistently described as low bureaucracy, high trust, and strong work-life balance , with leadership that understands what a good engineering environment looks like. What you will own Develop and optimize injection molding and overmolding processes for high-precision components Lead process development, mold trials, and production ramp-up for new programs Improve process stability, repeatability, and yield , especially on tight-tolerance parts Partner with tooling resources on DFM, mold design, and manufacturability Help expand internal plastics capabilities, including overmolding applications and future equipment Serve as the go-to plastics/process expert within a broader engineering team Work cross-functionally with engineering, operations, and program teams Must-have experience Hands-on injection molding process engineering experience Direct experience with overmolding or insert molding in a production environment Strong process development, troubleshooting, and optimization skills Experience working closely with tooling and mold design Strong additional signals Experience with multi-shot, insert molding, or material bonding processes Experience with small or tight-tolerance components Exposure to high-performance polymers (PEEK, nylons, etc.) Background in regulated manufacturing (medical device preferred, not required) Experience with validation (IQ/OQ/PQ) or scientific molding approaches What you can expect Direct impact on next-generation medical and surgical technologies 4-day work week (10-hour shifts) Private company environment with minimal red tape A team that values engineering input and practical problem solving Strong work-life balance with limited off-hours disruption Opportunity to build and shape a growing plastics capability Competitive benefits package Target compensation: $120,000
- $170,000 (flexible based on experience) What this role is not Not a siloed or purely support engineering role Not a constant firefighting production environment Not a large corporate structure with layers of approval If you have experience in injection molding and overmolding and want a role where you can actually influence how things are built and scaled, this is worth a conversation.
