Ready to put your skills to work in a business that still values true engineering craft while continually investing in the future? We're on the lookout for a CNC Miller with strong Heidenhain experience to join a forward-thinking precision manufacturing team in Portsmouth.

Select tooling, cutting data, and machining strategies
Set and operate 3-axis, 4-axis & 5-axis machines
Read and interpret complex engineering drawings
Perform first-off and in-process inspections
Work with engineering and production teams to improve processes
What We’re Looking For
Proven experience as a programmer
Confident with Heidenhain controls (essential)
Hypermill experience preferred: other CAD/Cam software also considered
Strong knowledge of tooling, feeds & speeds
Good understanding of GD&T
Quality-focused mindset and problem-solving ability
Able to work independently and as part of a team
