Role Overview * Own sustaining engineering for assigned products (doorsets, vision panels, hardware, washroom items). * Triage, root-cause and permanently fix product and manufacturing issues (8D, 5-Whys, fishbone). * Lead ECR/ECN change control, updating drawings, specs, BOMs and work instructions. * Deliver value engineering and standardisation (cost-down, de-risk, supply continuity, obsolescence). * Partner with Production on DFM/DFA, jigs/fixtures. * Build and test quick prototypes; run verification on updates before release. * Keep product data clean and current in PDM/ERP; maintain golden thread of revisions. * Support global sites (UK/US/AUS) with build issues, supplier queries and installer feedback. * Collaborate with Quality to close NCRs/CAPAs and prevent recurrence. * Prepare crisp technical packs: updated drawings, labels, assembly guides and install / O&M content. What You'll Do Day-to-Day * Investigate factory / field problems, define CTQs, implement and validate fixes. * Create / modify 3D CAD and BS 8888-compliant 2D drawings; run tolerance stacks. * Run pilot builds; prove process capability with Production; hand over robustly. * Work with Supply Chain on alternate parts, cost savings and risk mitigation. * Track actions and outcomes against clear KPIs (FPY, scrap, warranty, unit cost, OTIF). ## Related Videos - [How to Domain Model – An example from manufacturing](https://www.wearedevelopers.com/videos/742-how-to-domain-model-an-example-from-manufacturing) - [XR Demystified: Separating Facts from Fiction in 2024](https://www.wearedevelopers.com/videos/1117-xr-demystified-separating-facts-from-fiction-in-2024) - [Implementing smoke testing and proactive monitoring in production](https://www.wearedevelopers.com/videos/171-implementing-smoke-testing-and-proactive-monitoring-in-production) - [TresJS a new declarative ThreeJS as Vue components](https://www.wearedevelopers.com/videos/543-tresjs-a-new-declarative-threejs-as-vue-components) - [Google Gemma and Open Source AI Models - Clement Farabet](https://www.wearedevelopers.com/videos/1354-google-gemma-and-open-source-ai-models-clement-farabet) - [Proactive monitoring and smoke testing in your production environment](https://www.wearedevelopers.com/videos/139-proactive-monitoring-and-smoke-testing-in-your-production-environment) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Why Event-Driven Architecture Isn’t About Speed (and When You Actually Need It)](https://www.wearedevelopers.com/magazine/745-why-event-driven-architecture-isn-t-about-speed-and-when-you-actually-need-it) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Are design and development really just the same thing?](https://www.wearedevelopers.com/magazine/520-are-design-and-development-really-just-the-same-thing) - [UK Business Culture and Etiquette](https://www.wearedevelopers.com/magazine/326-uk-business-culture-and-etiquette)
