ARE YOU THE VOICE OF LEAN?
We don't want someone who talks about continuous improvement. We want someone who
lives it — on the shop floor, with the teams, every day. Thales UK builds technology that
matters. As our Lean Leader in Crawley, your mission is to make our manufacturing
operations sharper, faster, and better — for good.
You'll be the go-to expert for Lean Continuous Improvement (LCI) across our Glasgow site. That means embedding robust problem solving (PDCA) and Lean thinking into daily operations, not just running workshops. You'll coach teams, lead transformations, and drive measurable results across Quality (FPTY), Delivery (OTDIF) and Cost (UPC).
This is a hands-on, high-visibility role. You'll work directly with Site Production, Engineering, Our Autonomous Production and Repair Unit (APRU) Managers, Head of Industry and the UK Head of Lean Continuous Improvement — and your fingerprints will be on the culture, not just the metrics.
Experience with Oracle, iObeya, PowerBI, Minitab or MES systems? Even better.
This role will require SC Clearance. It would be advantageous if currently held, however, if not currently held, it is a requirement that the successful applicant will undergo, achieve, and maintain SC Clearance. Please visit the UKSV website for further guidance.
To be eligible for full SC, you generally need to have resided in the UK for the last 5 years. In some circumstances, a minimum of 3 years’ residence in the UK over the last 5 years may be accepted, with additional overseas checks.
For further details of the evidence required to apply for Baseline and Security Clearance please refer to the National Security Vetting (NSV) Agency - United Kingdom Security Vetting - GOV.UK (www.gov.uk)
