About the position

About Plextek:

Plextek is an electronics design consultancy working on a diverse range of innovative and challenging technologies for the communications and electronics industries.

We provide consulting and design services across a broad range of sectors (consumer, industrial, automotive, medical and security & defence). Consequently, the work is varied, interesting and often technically challenging.

We are located 10 miles south of Cambridge in the semi-rural village of Great Chesterford, with ample parking, a direct train link to Cambridge and easy access to the M11.

 

About the role:

The Mechanical Design team are seeking to recruit an enthusiastic and flexible Consultant Mechanical Design engineer to enhance our mechanical design capability.  The successful candidate will have responsibility for the mechanical design elements of a wide range of projects and products both new and existing.

Design Consultancy work is varied and interesting. Our projects are largely based around Plextek’s core radio capability and range from low volume specialist equipment, through to complex consumer products designed for low cost, high volume manufacture. In addition, you will work on our own suite of products which range from vehicle tracking through to biometric monitoring and solid-state radar.

This is a challenging role requiring a breadth of knowledge and experience rather than a narrow specialism.

 

Duties / Responsibilities:

  • Liaison with other disciplines and working in project teams, provide input into project proposals, create design schemes and concepts.
  • Act as a point of expertise within the organisation to provide guidance and mentoring to the team and wider business.
  • Responsible for creative and innovative designs primarily using the PTC Creo 3D CAD tool or Solidworks.
  • Hands-on development, including building prototypes and pre-certification testing of elements such as ingress protection sealing, thermal management and/or mechanical integrity.
  • Produce drawings and BoMs and provide input into manufacturing data packs. Engineering drawings to BS8888. Geometric tolerancing. Tolerance analyses.
  • Be the technical lead at design reviews, provide technical support in client facing meetings.
  • Manage the mechanical aspects of a project from concept through to manufacturer hand-over, provide client support and dealing with suppliers both locally and internationally.
  • Production of technical reports and presentations as well as contributing to raising the profile of Plextek capabilities through the publishing of articles.
  • When required manage external resource which provides additional capacity to the team.

3D CAD packages, preferably Creo including document and revision control

Mathematical approach to calculating loads, torques, friction forces, moments of inertia, bending moments, stresses etc.

Use of sealing techniques to provide ingress protection against liquids and solids.

Understanding of principles of EMC protection and RF isolation.

Knowledge of thermal control for electronics, using both passive and active methods.

Corrosion prevention/protection strategies.

Understanding of good design for assembly and both low and high volume manufacturing processes. And be able to demonstrate examples of their direct involvement in a variety of products designed.

Working knowledge of diverse manufacturing process including injection-moulding, sand and die-casting, sheet metal fabrication, precision machining, Additive Manufacturing using multiple materials as well as practiced use of appropriate rapid prototyping techniques.

The ability to estimate what time is required to complete a design and to estimate tooling costs and piece part costs across a wide range of parts and manufacturing volumes.

Materials selection.

A logical and methodical approach to problem solving.

 

Advantageous experience:

Knowledge of RF, Analogue & Digital layout considerations for mechanical design.

An understanding of FEA simulation techniques.

Experience of working directly with UK and Overseas sub-contract manufacturers.
