About the role
Our client, a growing manufacturer in Bognor Regis, is looking for a hands-on Product Development / NPI Engineer to take product concepts and mechanical designs through practical development, prototyping, testing and preparation for manufacture — making sure products are robust, manufacturable and ready for a smooth production handover. The role supports two areas of the business: locks and hardware for metal gates, and a more project-driven offshore division that involves close technical collaboration with customers and their engineering teams. The emphasis is on turning designs into reliable working products rather than purely conceptual design. Pay: £55,000 per year. Reporting to: Engineering Manager, working closely with the Product Manager, Chief Engineer, CAD Design Engineer, Engineering Technician and CNC Setter / Operator, as well as Operations, Quality, Procurement, Sales and Marketing. The role Product development and NPI - Support and progressively own the development of assigned products from concept through prototype, validation and production handover. - Review concepts and mechanical designs for function, fit, reliability, manufacturability and assembly. - Develop and modify 3D CAD models, engineering drawings and product details. - Plan, build or coordinate prototypes and use practical fault-finding to refine designs. - Support technical assessment of customer-specific applications. DFMA and production preparation - Apply Design for Manufacturing and Assembly (DFMA) principles to simplify products and support cost-effective manufacture. - Lead and take part in cross-functional 3P (Production Preparation Process) workshops. - Build low-cost prototypes, mock-ups and trial assemblies before production scale-up. - Incorporate practical error-proofing (poka-yoke) into products, fixtures and assembly methods. - Design, develop and validate simple production tooling, jigs, fixtures and assembly aids. Testing, validation and quality - Plan and carry out practical product testing, and design or coordinate test rigs and methods. - Support validation of reliability, longevity and real-world suitability before release. - Escalate significant design, compliance, safety or customer-impacting decisions for senior review. Documentation and handover - Develop drawings, specifications, Process Flow Diagrams, PFMEA and work instructions. - Support accurate BOMs and complete engineering information before release. - Work with Operations during pilot and first builds to resolve design, assembly and process issues. Collaboration - Work with Operations, Quality and Procurement to evaluate supplier capability and production risks. - Provide practical technical input to external suppliers producing prototypes, components or assemblies. - Mentor less-experienced technical team members through suitable NPI work. What you'll bring - A mechanical engineering qualification or equivalent practical experience. - Experience in product development, NPI, manufacturing / production engineering or a similar hands-on mechanical role. - Experience with 3D CAD and engineering drawings (Onshape, SolidWorks or similar). - A good understanding of DFMA, tolerances, materials, assembly methods and common manufacturing processes. - Working knowledge of CNC machining, sheet metal, laser cutting, casting, forging, moulding, fabrication, finishing and additive manufacture. - Hands-on experience with prototyping, testing, fault-finding, jigs / fixtures or test rigs. - Strong attention to detail and good communication skills. - Comfort working in a growing SME where practical ownership is valued. Desirable: experience with 3P, PFMEA, process-flow development, work instructions or lean production-preparation methods. Traditional complex toolmaking experience is not required.
