Working hours: Monday to Thursday 7:45 am to 04:30 pm and 7:45 am to 1:00 on Fridays

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.

Required Skills & Technical Competencies

• Mechanical fitting experience in precision engineering, aerospace, defence, or similar high-integrity sectors.

• CNC machining competence — Setting & operating

• Strong manual machining capability for bespoke and prototype work.

• Ability to interpret engineering drawings, GD&T, tolerance stacks, and aerospace specifications.

• Experience working to tight tolerances (±0.01 mm typical).

• Proficiency with inspection tools: micrometers, verniers, height gauges, bore gauges; CMM familiarity beneficial.

Ideal Candidate Profile

• A versatile engineer comfortable switching between hands-on fitting, CNC machining, and manual machining depending on workload.

• Analytical mindset with a natural ability to troubleshoot and resolve engineering challenges.

• Enjoys prototype work, iterative development, and supporting R&D innovation.

• Works effectively in a small, fast-paced subcontract environment with varied daily tasks.

• Takes pride in producing high-accuracy, safety-critical components for aerospace and defence.

• Strong communicator who collaborates well with engineers, machinists, and quality teams.

Qualifications & Experience

• Time-served apprenticeship or equivalent in Mechanical Engineering, Manufacturing, or Precision Engineering.

• 3–5+ years' experience in machining, fitting, or hybrid roles.

• Aerospace/defence sector experience highly desirable.

• Additional training in CNC programming, metrology, or advanced machining advantageous.

Compliance & Safety Requirements

• Adherence to AS9100, ISO9001, and internal quality procedures.

• Commitment to safe working practices, PPE use, and risk-based decision-making.

• Ability to complete required documentation for traceability and compliance.

Outputs & Deliverables

• High-integrity machined components meeting drawing and tolerance requirements.

• Fully assembled and tested mechanical systems/prototypes.

• Accurate inspection records, build documentation, and non-conformance reports.

• Continuous improvement suggestions for machining, assembly, and workflow.
