Mechanical Engineer

Mechanical Engineer

Location: Braintree

Employment Type: Permanent

We are seeking a highly skilled Mechanical Engineer to join our team. This role is ideal for someone who thrives in a technical environment, enjoys taking ownership of complex design challenges, and can deliver high‑quality engineering solutions across multiple projects.

You will play a key role in designing, developing, and industrialising next‑generation high voltage components and systems, ensuring reliability, manufacturability, and technical excellence.

Key Responsibilities

• Design and develop HV components and systems including insulation structures, connectors, and mechanical assemblies.
• Produce detailed 3D CAD models and engineering drawings in accordance with BS 8888.
• Apply dielectric design principles to manage electric field stress, insulation integrity, and long‑term system reliability.
• Take full ownership of design solutions from concept through prototype validation and industrialisation.
• Plan and conduct prototype and HV withstand testing, interpreting results to refine designs.
• Use engineering calculations and FEA tools to correlate analysis with testing and optimise mechanical and electrical performance.
• Validate engineering decisions using evidence, testing results, and sound engineering judgement.
• Produce clear and structured technical reports, design documentation, and presentations.
• Ensure solutions are robust, manufacturable, and aligned with cost, schedule, and technical constraints.
• Independently identify root causes and implement effective engineering solutions.
• Communicate technical concepts and design decisions clearly across multidisciplinary teams.
• Build strong working relationships with engineering, manufacturing, suppliers, and customers.
• Understand customer technical requirements and translate them into practical engineering solutions.
• Represent the engineering team confidently during technical discussions with customers.
• Act as a trusted technical contributor and role model within the team.
• Guide and mentor less experienced engineers with constructive feedback and knowledge sharing.
• Proactively identify opportunities to improve designs, processes, and engineering best practices.
• Develop expertise continuously and apply new learning to strengthen technical output.

About You

• Proven track record delivering multiple technical design projects.
• Demonstrable experience producing mechanical designs across several projects.
• Strong understanding and application of GD&T in accordance with BS 8888.
• Evidence of practical engineering application in previous roles.
• Ability to justify design decisions using engineering principles, calculations, and data.

Desirable Experience

• Prototype testing, result interpretation, and iterative design refinement.
• Experience correlating test data with analysis and improving designs using FEA.
• Background in concept generation, ideation, and industrialisation of mechanical systems.
• Bachelor’s degree in Mechanical Engineering or equivalent – or significant relevant experience.
