CNC Machinist - Hamburg Factory (m/f/d)

Location: Hamburg (Factory)

Job Type: Full-time

Salary: Competitive

Equity: Benchmarked

Role Overview:

Program, set and run advanced CNC machines to deliver high-precision components for aerospace, defence, energy and robotics customers.

You will own the full machining lifecycle — from CAM programming and first article prove-out to cycle time optimisation and repeat production — helping build the most efficient factory in the network.

This is a hands-on, high-ownership role for someone who takes pride in tight tolerances, clean setups, and continuous improvement.

Key Responsibilities:

• Program, simulate and optimise CNC toolpaths (3-axis, 5-axis and mill-turn where applicable)

• Set, prove-out and run jobs to aerospace and defence standards

• Reduce cycle times and improve machine utilisation

• Design and improve fixturing strategies

• Select tooling and cutting parameters for challenging materials (e.g. aluminium, steels, titanium, Inconel)

• Maintain high quality standards and ensure first-time-right manufacturing

• Support new part introduction (NPI) from drawing to production

• Contribute to DFM feedback for customers

• Work closely with engineering and MasonOS software teams to improve data capture, scheduling and automation

• Standardise programming approaches across sites as we scale

Required Skills:

• Strong CAM programming experience (e.g. Fusion, Hypermill, Mastercam or equivalent)

• Proven ability to machine tight tolerances (±0.01mm and below where required)

• Experience setting and running high-end CNC machines (e.g. Hermle, DMG Mori, Mazak or similar)

• Deep understanding of feeds, speeds, tooling strategy and workholding

• Experience in aerospace, defence or other high-spec industries preferred

• Ability to read and interpret complex engineering drawings and GD&T

• Comfortable working in a fast-moving, high-ownership environment

Nice To Haves:

• 5-axis simultaneous machining experience

• Experience with probing, automation or pallet systems

• Knowledge of AS9100 / ISO9001 quality systems

• Interest in robotics, factory automation and data-driven manufacturing

What We Offer:

• Work on mission-critical aerospace and defence components

• Access to advanced machine tools and evolving automation

• Equity participation in a scaling factory network

• Opportunity to influence programming standards across sites

• High-performance culture focused on continuous improvement
