Job 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
