Senior Full Stack Developer

Company Description

Rydal Group is a UK-based IT and Telecoms Managed Service Provider serving the B2B market. Founded over 17 years ago, the business remains founder-led and independently owned, with no VC or private equity backing. This allows us to make long-term decisions based on service quality, infrastructure investment, and client outcomes rather than short-term financial pressure.

We employ over 110 team members across four UK locations, including our own data centre and ISP. Today, we support more than 3,000 B2B clients, 6,000 consumer clients, and a growing number of UK channel partners which launched last year.

Our focus is on delivering dependable IT, connectivity, and communications services, backed by infrastructure we own and control. Utilising Ai / Ai Agents at the forefront of our software offering is going to play a huge role in our road map.
