Role Summary

We are looking for an experienced Electronics Engineer to be involved in the projects we complete from design, specification, test and build and commissioning.

We use a combination of in-house electronics and off the shelf products to put together bespoke systems. Our own designs span analogue, digital, FPGA and microcontroller work. The ideal candidate will hold a broad fundamental understanding of this type of technology and ideally some existing experience in the rail industry.
