Mechanical Design Engineer – Tooling & Repurposing Focus

Location: On-site in Milwaukee, WI (4-5 days/week)

Contract: Open-ended (6–12 months minimum, potential for full-time conversion)

The Opportunity

We're looking for a high-impact mechanical design engineer with a passion for solving complex mechanical challenges — someone who thrives in hands-on environments, and is driven to innovate in the design and repurposing of legacy manufacturing equipment.

This isn’t a job for someone who wants to follow a process. It’s for a creative system builder, a mechanically curious problem-solver who’s excited to rethink tooling, revamp aging systems, and design next-gen solutions for a fast-moving, niche machining and accessories business.

What You'll Be Doing

• Lead the design, redesign, and reconfiguration of existing manufacturing tools and machines to support new product development
• Conceptualize and implement mechanical systems that blend old and new technologies, adapting legacy equipment to meet modern production needs
• Collaborate across teams (engineering, machining, production) to create robust, manufacturable solutions
• Prototype tooling and systems that are durable, serviceable, and easy to maintain
• Take full ownership of projects — from concept to production handoff

Ideal Experience

• 7+ years in custom machine design, tooling, or mechanical system development
• Proven experience repurposing and modifying existing manufacturing equipment
• Strong background in metal-based manufacturing (carbides, raw materials)
• Proficiency in CAD tools (SolidWorks preferred), mechanical analysis, FEA, and GD&T
• Bonus: Exposure to injection molding or automation/robotics

You Might Be a Fit If You…

• Are motivated by impact, not job titles
• Thrive in uncertainty and love solving mechanical puzzles
• Have a deep respect for craftsmanship, both in engineering and execution
• Aren’t afraid to challenge the norm and take calculated risks
• Move fast, communicate clearly, and can make confident decisions on the fly

Culture Fit

• Candid, honest, and transparent communication style
• Peer-to-peer accountability with no room for ego
• Empowered to make your own decisions and trusted to own your work
• A team that values speed, agility, and cross-functional collaboration

Non-Negotiables

• A diverse engineering background — not siloed in one vertical or type of product
• Innate curiosity and a passion for mechanical creativity
• Willing to get hands-on, roll up sleeves, and build the solution
• Must care deeply — about the work, the details, and the end result

Bonus Points If You've Worked At

• Custom machine builders
• Advanced manufacturing companies with in-house engineering teams

Want to be part of something innovative and real?

Let’s build something great — and maybe rebuild a few things along the way.
