Mechanical Design Engineer - Contractor

Mechanical Design Engineer (Contractor) (VRF-087) UK & Prague Vacancy listed 15/07/2026 Details Role

Purpose:

We require a Mechanical Design Engineer to design enclosures for electrical and electronic systems for a wide range of customer applications focussed on electrification, including battery management, power conversion and electric vehicle control systems. The successful candidate will package custom and off-the-shelf electrical/electronic components, external connectors, low-voltage harnesses and high-voltage/current interconnect into custom or modified enclosures, dealing with cooling requirements and meeting relevant industry standards and produce cost-effective and manufacturable designs.

They will liaise with suppliers and manufacturers and work with the wider multi-disciplinary engineering team to support the delivery of effective engineering solutions.

• Work closely with the electronics and EDS team and other engineering disciplines, to develop modern, innovative, and practical electrical system solutions
• Design of enclosures with electro-mechanical component package modelling and associated mechanical fixings, etc. to support modules and harnesses.
• Design of solid components from folded sheet metal, machined solid or 3D printed plastic
• Production of 2D manufacturing drawings from 3D models and designs
• Develop 3D wiring harness models within the enclosure
• Management of thermal interfaces such as cooling fins, liquid flow-through cold plates and vapour chambers
• Support Design for Manufacture reviews and work with suppliers and manufacturing partners to optimise designs for manufacturability and cost
• Develop and manage component database for electrical components for 3D packaging
• Manage assembly structures and BOMs, adhering to company engineering change control processes
• Delivery of engineering tasks and reporting of progress and issues in line with project milestones.

• Degree or similar in automotive, electrical/electronic or mechanical engineering
• Extensive experience (5 years+) relevant design experience of packaging and modelling of electrical assemblies and components and LV & HV wiring harnesses gained across multiple projects in a prototyping and production environment.
• Experience of creating 2D component drawings and manufacturing assembly drawings
• Experience of creating and maintaining 3D electrical component database/ catalogue.
• Experience of thermal management techniques including liquid cooling
• Advanced capabilities in ECAD software tool e.g., Catia V5/V6 or NX

• Experience of working in a relevant industry (such as automotive, rail, marine, energy storage aerospace)
• Experience of high voltage busbar/PDU design and required creepage/clearance rules
• Understanding of structural / stress / finite element analysis

• Knowledge of GT&D and the correct application into component manufacturing drawings.
• Knowledge of relevant material science including thermal properties, corrosion resistance (including galvanic corrosion), strength and durability.
• Understanding of mechanical manufacturing processes and Design for Manufacture/Assembly
• Understanding of tolerance analysis

• Quality-focussed with an attention to detail
• Flexible and enthusiastic
• Good problem solving and analytical skills
• Strong communication skills – including report writing and presentation
• Self-motivated and enjoys working within a team environment
• Willingness to accept responsibility and challenges required to achieve objectives
• Commitment to professional development and continuous learning

• You must be eligible to work in the UK or CZK and have no restrictions for world-wide travel.
• This role is based at our Head Office in Coventry, UK, or our engineering Office In Prague, Czechia, with flexibility for remote working.
• Working hours are 0900 to 1700, 5 days a week, however some travel is expected, and flexible working patterns are essential to the role.
