Senior Prototype Programmer

We are seeking a highly capable Senior Prototype Programmer to strengthen Domin’s in‑house prototyping capability. Working closely with design engineers and machinists, you will lead CAM programming and machining strategy for complex prototype components, helping transform concepts into functional hardware quickly and efficiently. The role is primarily focused on multi‑axis milling and mill‑turn machining, with responsibility for developing machining processes, workholding solutions, fixtures, and manufacturing methods for technically challenging parts. You will help advance Domin’s capability in machining difficult materials and post‑machining additive manufactured components, while improving manufacturing speed, quality, and performance. This is a hands‑on role combining advanced CAM programming with practical machining involvement. Alongside programming and process development, you will support machine setup, prove‑out activities, tooling selection, and prototype manufacture where required to solve technical challenges and accelerate development. The successful candidate will bring deep machining expertise, strong technical judgement, and a proactive approach to delivering high‑quality prototype components in a fast‑paced engineering environment.

Key Responsibilities:

• Program, prove out, and support manufacture of technically challenging components, maintaining practical involvement in machining operations where required to accelerate development and resolve manufacturing issues.
• Design and develop fixtures and work holding solutions for machining complex components.
• Work closely with tooling suppliers to optimise cutting tool selection and machining performance for difficult materials and geometries.
• Collaborate closely with design engineers and machinists to improve manufacturability, accelerate prototype iteration, and identify manufacturing risks early in development.
• Drive the continued growth of Domin’s in‑house prototype manufacturing capability, reducing dependency on external suppliers and enabling increasingly complex work to be completed internally.
• Provide accurate technical input on manufacturing times, process risk, and job progress to support effective scheduling and delivery planning.
• Mentor and support less experienced team members through hands‑on technical guidance and knowledge sharing.

Requirements:

• 5 years’ experience in advanced CNC programming within a high‑performance or technically demanding engineering environment.
• Strong hands‑on capability in complex CNC machining environments, particularly multi‑axis milling and mill‑turn operations.
• High level of proficiency using CAM software.
• Proven ability to determine machining methods for complex or difficult‑to‑manufacture components.
• Experience designing and manufacturing jigs, fixtures, and workholding solutions.
• Strong understanding of cutting tool selection, machining dynamics, and tooling strategy for complex machining applications.
• Ability and willingness to set, prove out, and run machining operations when required.
• Strong communication skills with the ability to identify and escalate technical or delivery risks early.

Beneficial Requirements:

• Experience machining hardened materials and post‑machining additive manufactured components or castings.
• Experience in Autodesk Fusion CADCAM package.
• Experience programming or operating CNC WEDM or cylindrical grinding machines.
• Experience in high‑performance subcontract machining; motorsport, aerospace, advanced manufacturing, hydraulics.
• Understanding of additive manufacturing processes and their impact on downstream machining strategy.
• Experience in Fanuc and Heidenhain CNC controllers.
