Senior Maintenance Technician – Injection Molding

Job Title: Senior Maintenance Technician – Injection Molding
Location: Shelby Township, MI
Company: Atomic Industries
Reports To: Maintenance Manager / Plant Manager

Atomic Industries is reinventing how the world makes things. From cars and aerospace systems to medical devices and packaging, most physical goods begin life in a mold or are shaped by a manufacturing tool. Producing these tools has always been slow, manual, and dependent on scarce expertise, taking weeks or months. We’re changing that.

At our Detroit headquarters, we combine the industrial DNA of America’s manufacturing heartland with the speed, intelligence, and precision of Silicon Valley. Our AI-driven platform tackles the hardest problems in geometry, process planning, and fabrication, collapsing production timelines from months to days and soon, minutes. We don’t just build software; we run a fully operational factory where our technology produces production-grade tooling every week, enabling tight feedback loops and rapid iteration.

Backed by top-tier investors, we’re restoring speed, flexibility, and capability to the American industrial base. Our mission is to make manufacturing as agile and scalable as the digital world, and in doing so, rebuild the infrastructure of the physical economy.

We’re hiring a Senior Injection Molding Maintenance Technician to lead preventative, corrective, and emergency maintenance across our molding operations. You’ll be responsible for keeping our presses, robotics, and support equipment running at peak performance with minimal downtime.

This is a hands-on role requiring deep mechanical, electrical, and hydraulic knowledge—especially with large-tonnage machines (500T–2000T). You’ll also play a key role in shaping our PM program, tracking downtime data, and helping scale a next-generation factory.
