Mechanical Fitter / Machinist
Permanent
Salary competitive
Working hours:
- Monday to Thursday: 7:45 am to 04:30 pm
- Friday: 7:45 am to 1:00 pm
Role Purpose
The Mechanical Fitter / CNC Machinist provides dual-discipline capability across mechanical assembly/fitting, CNC machining, and manual machining, supporting both production and prototype/R&D activities. The role ensures high-integrity components and assemblies are manufactured, assembled, tested, and delivered to aerospace/defence standards.
Core Responsibilities
- Mechanical fitting & assembly — Build, align, assemble, and test mechanical systems, sub-assemblies, and prototypes to engineering drawings and specifications.
- CNC machining operations — Program (basic), set, and operate CNC mills/turns to produce tight-tolerance components for aerospace/defence applications.
- Manual machining — Manufacture one-off parts, tooling, fixtures, and rework items using manual lathes, mills, grinders, and hand tools.
- Engineering problem-solving — Diagnose assembly issues, machining inaccuracies, tolerance conflicts, and prototype build challenges; propose and implement practical engineering solutions.
- Quality assurance & inspection — Conduct first-off inspections, dimensional checks, and verification against aerospace/defence standards (AS9100 aligned).
- R&D and prototype support — Work with design and engineering teams to develop prototypes, experimental assemblies, fixtures, and tooling.
