About This Role
Are you an engineering student who learns best by doing? We are looking for a Subtractive Manufacturing Engineering Co-Op to join our team. This is a hands-on role where you will work directly alongside experienced engineers — not just observing, but actively contributing to real production work, meaningful process improvements, and documentation that the team will use long after your term ends.
You will gain direct exposure to 3-, 4-, and 5-axis machining, CNC programming, fixture design, and quality system requirements in a precision manufacturing environment. If you are curious, mechanically inclined, and ready to roll up your sleeves and make an impact, this co-op is for you.
What You'll Do
CNC Programming
-
Assist with the creation, simulation, and verification of CNC programs for 3-, 4-, and 5-axis milling and turning centers using hyperMILL, ESPRIT, and Fusion 360.
-
Support machine setups, prove-out runs, and first-article validation alongside experienced machinists and engineers.
-
Operate CNC machinery as needed to support prototype and production work, including basic setup, inspection, and troubleshooting.
Fixture Design
-
Support the design and fabrication of workholding and fixturing solutions to improve setup repeatability and minimize cycle time.
-
Collaborate with machinists and engineers to evaluate and refine fixturing approaches based on production feedback.
Documentation
-
Assist in documenting machining processes, tooling lists, and setup sheets to ensure repeatability and compliance with quality system requirements.
-
Help develop written work instructions that are clear and complete enough for others to independently execute part manufacturing.
-
Support updates to existing process documentation to reflect current best practices and any changes implemented during the co-op term.
Process and Continuous Improvement
-
Identify at least one continuous improvement opportunity during the co-op term, propose a solution, and support its implementation with guidance from the engineering team.
-
Participate in root cause analysis and corrective action activities for production issues.
