We are seeking a skilled CNC Operator with strong experience in programming, setting and operating 5-axis CNC machining centres to implement and embed our CNC capabilities. The role supports our advanced manufacturing operations for pressure vessel components where precision, quality and process reliability are paramount. The successful candidate will work closely with engineering, production and quality teams to machine high-integrity parts to exact specifications.
CNC Programming, Set-Up & Operation
* Program 5-axis CNC machines using CAM software (e.g., PowerMill, Fusion 360) based on engineering drawings and CAD models
* Set up 5-axis CNC machining centres from scratch, including fixtures, tools, work offsets, probing routines, and verification checks
* Operate and monitor machines to ensure consistent, reliable machining of additive[1]manufactured components
* Select appropriate tooling, work holding, and machining strategies to meet dimensional accuracy and surface finish requirements
* Optimise toolpaths and machining parameters to reduce cycle times and improve
productivity.
Process Creation & Embedding
* Develop robust machining processes for both new and existing components, ensuring
repeatability, efficiency, and traceability.
* Create standard operating procedures (SOPs), set-up sheets, and best-practice guidelines for 5-axis machining of pressure-vessel components
* Embed and implement these processes on the shop floor, training colleagues as needed and ensuring compliance across shifts or teams
* Continuously assess and refine machining methods, workflows, and documentation to support operational excellence
* Collaborate with engineering and additive manufacturing teams to ensure smooth integration between printed parts and CNC finishing processes
Manufacturing & Technical Support
* Interpret technical drawings, models, GD&T requirements, and production specifications
* Support the introduction of new components by developing machining strategies and
validating early production runs.
* Provide technical input into fixture design, tooling selection, and process improvement initiatives
Quality & Compliance
* Conduct in-process and final inspections using precision measurement tools; CMM
experience is an advantage.
* Ensure all machined components meet the stringent quality and safety standards expected for pressure vessel applications
* Maintain accurate production records, inspection data, and traceability documentation
* Identify and resolve machining deviations or non-conformances
Maintenance & Continuous Improvement
* Perform routine machine maintenance, calibration checks, and tool management
* Drive continuous improvement through tooling optimisation, process enhancements, and workflow efficiency projects
* Participate in lean manufacturing initiatives to reduce waste and improve overall productivity
Requirements
* Proven experience programming and operating 5-axis CNC machining centres (3-5 years preferred)
* Strong competence in machine set-up, tool selection and fixturing methods
* Demonstrated experience developing or standardising machining processes
* Ability to create clear set-up documentation, SOPs and machining standards
* Familiarity with machining high-integrity parts (e.g. aerospace, energy, pressure systems)
* Strong understanding of CAD/CAM tools, GD&T and precision measurement equipment
* Excellent attention to detail and commitment to quality and safety
Preferred Skills & Experience
* Experience with additive manufacturing workflows or hybrid processes
* Knowledge of high performance alloys and their machining characteristics
* Strong problem-solving skills with the ability to troubleshoot tooling process or machine issues
* Effective communication skills and the ability to train others

Who We Are
DEEP is an international design and engineering company on a mission to make humans aquatic. We're doing this by advancing ocean exploration through the development of new technologies that will enable humans to live and work in underwater environments for longer periods of time.
95% of the ocean is unexplored. Countless discoveries are waiting to be made, and knowledge gained, that will benefit our planet and all of humanity. The challenge is access, and that's where DEEP comes in. We're building subsea human habitats to enable research at depth and increase our understanding of the ocean, so we can help protect it.
DEEP Manufacturing
DEEP Manufacturing, based in Avonmouth (Bristol) offers advanced manufacturing capabilities and expertise in large-format metal additive manufacturing, rapid prototyping and material testing. Our advanced manufacturing facilities include a state-of-the-art robotics suite, offering 3D printing services and Wire Arc Additive Manufacturing (WAAM) capabilities which means we can deliver manufacturing projects in less time and at lower costs compared to traditional manufacturing processes.
Working at DEEP
We're a team of highly experienced engineering, operations and safety experts, with a funding model that allows us the freedom to think long term and pursue our mission without traditional restraints. We want to drive progress at the forefront of deep-sea innovation and discovery to become stewards of the ocean and reshape our relationship with our planet.
As an organization with multi-generational objectives and ambitious goals, the values we bring to work every day are critical:
Be Curious
- Find a better way and ask why not?". Answers are easy, questions are hard - ask original questions and be a curiosity catalyst
Be Exceptional
- It will take the most intelligent, talented and creative people on the planet working together to achieve DEEP's mission. Get it done, be relentless in your pursuit of excellence, and demand excellence from everyone.
Be Fearless
- No one has done this on the scale we're doing it before. Impossible things must be done for the first time. We are the team pushing boundaries
Be Good
- Cultivate passion and thrive together. Be safe, take intelligent risks, but never compromise the safety of the team - ever
At DEEP, we celebrate and embrace diversity and inclusion and strongly believe that the best innovations come from diverse perspectives. We invite applicants from all backgrounds to join us in creating technology that makes a meaningful impact on humanity, our oceans and planet.
