EPD Design Engineer

A world-leading designer and manufacturer of doorsets and accessories for mental-health and secure-care environments is recruiting for an EPD Engineer due to continued growth. The successful candidate will join their Product team and drive quality, cost and delivery improvements across in-market portfolio. This hands-on role sits between Design, Production, Quality, Supply and Installation Engineering. You'll stabilise and evolve current products, resolve field issues, value-engineer components, and ensure they can build right-first-time at scale. 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). Requirements SolidWorks proficiency and strong 2D drawing discipline (BS 8888). Proven EPD/sustaining engineering experience in electromechanical or building-product assemblies. Strong grasp of materials and processes (sheet metal, machining, coatings, joinery, glazing, assembly). Comfortable with hands-on bench work, fixtures and prototype builds. PDM experience preferred; working knowledge of ERP BOM/routing control. Competent in DFM/DFA, tolerance analysis and basic statistical validation. Clear communicator who thrives cross-functionally and under time pressure. Relevant qualification (BEng/BSc or equivalent). Nice to have: exposure to doors/hardware; familiarity with fire/smoke testing workflows; experience supporting multi-site manufacturing. Terms Hours: 8:00-17:00, Mon-Fri. Location: Sidcup. Hybrid: up to 2 days/week remote at line manager's discretion. Equipment: Laptop provided. Benefits: 25 days holiday (plus Bank Holidays), pension scheme, on-site parking and food
