The ‘Applications Engineer – Machining Technology’ will be at the heart of innovative machining research projects within the GKN Aerospace Technology Team. This role will be based in GKN’s new Global Technology Centre being built in Bristol, UK, and support world-wide machining development projects. The role requires a strong background in operating machine tools, ideally machine tools with Siemens 840D controllers, and machining of Titanium/Aluminium structures. The ideal candidate would also have production experience and competency/aptitude to support developments in NC programming and the use of machining simulation tools.

The candidate should be inspired by the prospect of applying and growing their knowledge to improve future generations of aircraft. They should be a strong self-starter, with an ability to quickly understand both the benefits and challenges likely to be faced in developing and implementing new machining processes.

The role has 3 fundamental aspects:

To interpret machining process requirements for parts/products

  • Work with Technology, Engineering and operations colleagues to understand the form, fit, function of aerospace parts, and business related process targets
  • Derive machining process requirements from the product and commercial requirements
  • Propose the machining development process, including work-holding and material removal strategies

Support CAM usage and development

  • Develop NC-programs for machining trials and demonstrator part manufacture
  • Analyse/foresee CAM/post-processing issues and be able to identify root cause
  • Understand and ideally use machining simulation tools in collaboration with internal/external resources

To operate machine tools

  • Conventional machining centres typically equipped with a Siemens 840D controller;
  • Collaborate with Technology and Operations colleagues to operate machining development cells aligned with more ambitious Technology objectives



  • Strong, accredited undergraduate degree in aerospace engineering, mechanical engineering, materials engineering, automotive engineering or similar.


  • Postgraduate degree themed on machining science technology or significant experience in defining, proving and implementing machining technology.

Specific Functional Capabilities, Knowledge and Skills Required:


  • Experience in operating machining centres.
  • Experience in selecting cutting tools/coolants, work holding systems, structured machining programme development and assessments.
  • Knowledge of aerospace materials.
  • A logical approach to problem solving and use of the appropriate tools.
  • A strong self-starter capable of accepting a vision/goal and taking the initiative to deliver.
  • Committed to supporting a culture of innovation.
  • An experienced and successful team-worker with a flexible working approach.
  • Good communication skills including verbal, written, preparing and giving presentations.


  • Programming for CNC machines using CAM software; preferably in CATIA.
  • Awareness of process optimization software.
  • Awareness of FEM simulation methods.
  • Background knowledge of a diverse range of processes, tooling philosophies.
  • Background knowledge of aircraft component manufacture.
  • Understands and has used tools such as Design of Experiments, Value Stream Maps and FMEAs.
