Description

Salary: Up to £65,000 + benefits (including equity/stock options)


Job Type: Full-time | Shift pattern to be confirmed


Overview


We're supporting a high-growth, technology-led manufacturing business building a next-generation production facility in London.


This is a genuinely unique opportunity to join at launch stage - working at the intersection of precision engineering, automation, and software. The focus here isn't just machining parts, it's helping shape how modern manufacturing is done.


You'll play a key role in programming, setting and running advanced CNC machines while contributing to a highly automated, data-driven environment.


The Role


You'll take ownership of the full machining lifecycle - from programming and prove-out through to optimisation and repeat production.


Key responsibilities include:



  • Programming, simulating and optimising CNC toolpaths (3-axis / 5-axis / mill-turn)

  • Setting, proving out and running high-precision components

  • Driving cycle time reduction and machine utilisation improvements

  • Developing and improving fixturing strategies

  • Selecting tooling and cutting parameters across a range of materials (aluminium, steels, titanium, Inconel)

  • Supporting new part introduction from concept through to production

  • Providing DFM feedback to improve manufacturability

  • Collaborating closely with engineering and software teams to support automation and process improvement

  • Contributing to standardisation as the operation scales


What We're Looking For


This role is deliberately different to a traditional machinist hire.


Technical capability matters but mindset is critical.


We're particularly interested in individuals who:



  • Are curious, adaptable and motivated to learn

  • Want to be part of a start-up or scale-up environment

  • Have an interest in automation, software and modern manufacturing systems

  • Are comfortable working closely with software engineers and technical teams

  • Take pride in their work and thrive in a high-performance, high-ownership culture


Experience in any of the below is beneficial:



  • CAM programming (Fusion 360, Hypermill, Mastercam or similar)

  • High-end CNC machinery (Hermle, DMG Mori, Mazak etc.)

  • Tight tolerance machining (±0.01mm or better)

  • Aerospace, defence or other high-spec environments


Why This Role is Different


This isn't a traditional machine shop environment.


The business is building a highly automated, software-integrated manufacturing model - meaning:



  • You'll work directly alongside software developers influencing how the factory operates

  • There's genuine opportunity to shape processes from day one

  • You'll be part of a team focused on continuous improvement and innovation, not just production


What's on Offer



  • Salary up to £55,000

  • Benefits package + equity/stock options

  • Access to advanced machinery and evolving automation systems

  • Opportunity to influence how a new facility is built and scaled

  • A high-growth environment with real long-term progression
