The role

This role encompasses two primary areas: firstly, circuit design and schematic entry along with the related system design/architecture, development, testing and qualification of the resulting products from prototypes to production handover; and secondly, the management, company-wide, of the component library and PCB design.

  • Communication – good written, verbal and presentation skills, the ability to communicate to the rest of the engineering team, to suppliers and sub-contractors, as well as directly to customers on occasion.
  • Familiar with usage of test equipment (e.g. high-speed oscilloscopes).

Key responsibilities

  • The lead schematic and PCB engineer in the company.
  • Managing sub-contractors for both some PCB design and for high frequency simulation.
  • Able to support other engineering team members with advice on the use of the CAD tools and company best practise.
  • Managing the company schematic and PCB libraries, including 3D models.
  • Help maintain the company component database and contribute to new part qualification and entry.
  • Test and debug new hardware on the bench to ensure correct operation.
  • Perform reviews on designs by other members of the team.
  • Help the QA department with approval of new PCB manufacturers and design sub-contractors (can involve travel).
  • Work closely with the CTO to define and refine Company Procedures for schematics & PCBs.

Useful additional expertise

The following are a benefit but not a requirement:

  • Knowledge/background in imaging.
  • Knowledge of JTAG-based test, in particular XJTAG.
  • Knowledge of FPGA design tools from the main vendors, in particular Vivado.
  • Knowledge of 3D CAD tools, in particular Solid Works.
  • Knowledge of C/C++ and VHDL.


In return we offer a position in a profitable and fast growing international company with high ambitions. Being part of a small team, you will be able to influence future product strategy, as well as streamline our design processes.
