Our teams are at the forefront of the change, managing life‐changing projects in Solar, Hydrogen, Nuclear, Renewables and Defence, and we want you to be part of that too.

We are looking for an experienced Senior Data Developer with an interest and experience in providing data analytic solutions utilising Power Apps and SQL to clients on major construction and infrastructure projects.
