About Us
DTC | A Codan Company is a technology company based in Whiteley, Hampshire. We specialise in the research and development of wireless and critical RF communication systems.
Our Engineers work at the edge of what is scientifically possible, developing secure, high-reliability systems used in real-world, mission-critical environments. Our technology is deployed nationwide by UK law enforcement and internationally across military, defence and government markets, enabling secure video, data, and communications across complex networked environments.

- This is a hands-on, engineering-led role, based primarily on-site in Whiteley, working closely with the Embedded and Hardware Team. While informal flexibility exists, regular on-site presence is essential.
