Principal Mechanical Engineer

Job description

Socode are working with a global high-tech engineering business developing complex precision systems used in advanced industrial applications. As their next-generation products move through critical development phases, they’re now looking to add a Principal Mechanical Engineer to their R&D team.

This is a senior, hands-on role where you’ll take ownership of major mechanical systems on complex electromechanical products — not just small sub-assemblies.

What will you be doing?
  • Leading mechanical development on new product programmes from technical specification through to production
  • Defining mechanical requirements around performance, reliability, cost, and serviceability
  • Producing detailed CAD, drawings, tolerances, and full bills of materials
  • Leading the build, integration, and testing of complex mechanical and electromechanical sub-systems
  • Selecting and validating cost-effective manufacturing methods and mitigating technical risks
  • Working closely with suppliers to source and manufacture components
  • Supporting product integration, system testing, and early-life issue resolution
  • Ensuring designs meet relevant standards and internal quality requirements
  • Contributing to technical documentation, training material, and customer support
  • Collaborating daily with R&D, Manufacturing, Product Management, and wider engineering teams
We’re looking for:
  • A Mechanical Engineering degree (or closely related discipline)
  • Extensive experience delivering products in high-technology R&D and manufacturing settings
  • Advanced 3D CAD capability in SolidWorks with working knowledge of simulation and analysis
  • A track record of owning products through the full development cycle, from early concept to production support
  • Strong practical understanding of a wide range of manufacturing methods, including CNC machining, sheet metal, moulded parts, castings, and additive methods
  • Solid background in designing and packaging electromechanical systems
  • Proven experience with motion and drive systems such as mechanisms, motors, linear rails, and bearings
  • Good working knowledge of materials selection, tolerancing, and mechanical reliability
  • Hands-on experience designing jigs, fixtures, and supporting manufacturing processes
  • A structured, analytical engineer who is comfortable with risk assessment and design reviews
  • Someone who can lead technically while remaining hands-on with detailed design
Nice to have:
  • Previous exposure to fluid-based precision systems
  • Understanding of pneumatics, fluid handling, or safe machinery design
