Mechanical Fitter / Machinist

Permanent

Salary competitive

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.
