Rate: £50 to £65 per hour (indicative outside IR35)
Contract Length: 3–6 months
Working Arrangements: On‑site presence required, with some flexibility depending on project phase
An established technology business in Colchester is seeking an experienced Applications Developer to support a series of embedded, GUI‑driven software projects. This contract role sits within a multidisciplinary engineering team and focuses on delivering high‑quality application features, on‑screen display tools, and user‑facing interfaces using C++ and Qt, tightly integrated with embedded hardware.
This role has an indicative outside IR35 determination, meaning we can accept candidates who wish to operate through their own Personal Service Company (PSC).
