Senior Mechanical Design Engineer Building Services

Senior Mechanical Design Engineer About the Role

Our client, a specialist manufacturer of bespoke machinery, is looking for a highly motivated and experienced Senior Mechanical Design Engineer to join their engineering team. The successful candidate will play a key role in the design and development of custom-engineered machinery for specialist industrial applications, supplied to customers across a range of international markets.

This is a hands‑on engineering role requiring strong mechanical design expertise combined with the ability to lead small design projects and coordinate the activities of a team of 2-3 engineers. The position offers the opportunity to work on technically challenging, custom-engineered equipment from concept through to installation and commissioning.

• Design bespoke machinery, assemblies and production systems using 3D CAD (Autodesk Inventor), developing innovative solutions for coating, printing, laminating, drying, winding and web transport processes.
• Produce detailed manufacturing and assembly drawings, bills of materials, and Functional Design Specifications alongside the Systems Engineers.
• Carry out engineering calculations covering structures, shafts, bearings, drives, pneumatics and machine dynamics, and select suitable materials, components and manufacturing processes in line with machinery legislation, harmonised standards and customer specifications.

• Manage small- to medium‑sized design projects from concept through manufacture and commissioning, coordinating and prioritising the work of up to three mechanical design engineers.
• Monitor progress against engineering schedules and milestones, participate in design reviews and technical risk assessments, and identify and mitigate technical risks.
• Review and approve engineering designs, calculations and technical documentation produced by other engineers, liaising with Project Managers to ensure successful delivery.

• Work closely with controls engineers, manufacturing, commissioning teams and suppliers, supporting Purchasing with technical component selection and supplier enquiries.
• Provide engineering support during machine build, testing, Factory Acceptance Testing (FAT) and site commissioning, attending customer meetings with occasional UK and international travel.
• Manage Non‑Conformance Reports (NCRs) raised against your projects, mentor junior engineers, and contribute to engineering standards, design practices and improvements in machine performance, reliability and cost‑effectiveness.

• Minimum 7 years' experience in mechanical design within industrial machinery, automation or special‑purpose equipment, with proven experience designing bespoke (not catalogue‑based) machinery.
• Experience leading engineering tasks or small design teams.
• Strong 3D CAD experience, Autodesk Inventor preferred.
• Good understanding of manufacturing techniques (fabrication, machining, assembly) and mechanical power transmission systems, with experience producing engineering calculations and technical documentation.
• Excellent communication and organisational skills, with the ability to manage multiple projects and priorities simultaneously.

• Degree qualified in an engineering discipline, or substantial experience in a similar role.
• Experience with coating, printing, laminating, converting, web handling, winding or roll‑to‑roll processing equipment, including precision process, tension control or vacuum systems.
• Knowledge of Machinery Regulation / CE & UKCA compliance requirements, and understanding of ATEX environments and hazardous area design.
• Experience supporting FAT, SAT and commissioning activities.

• Innovative and practical problem solver, self‑motivated with strong attention to detail.
• Able to balance technical excellence with commercial awareness.
• Strong leadership and mentoring capability, and a collaborative team player.
• Customer‑focused, with a willingness to take ownership and drive projects to completion.

• Salary of circa £50k, with flexible working hours and working only Monday - Thursday
• Opportunity to work on highly specialised bespoke machinery projects, with exposure to a wide range of engineering challenges and technologies.
• Career progression within a growing engineering business.
• Collaborative and supportive engineering environment.
