The Company
An established, profitable UK technology business running a large-scale, business-critical platform in a regulated, mission-critical sector. Very high transaction volumes, a growing enterprise customer base, and a serious engineering bar. The team is mid-modernisation - consolidating delivery, evolving a mature C# platform, and standing up a proper architecture function. Strong senior practitioners already in place (Tech Leads, Staff Engineers, a Principal Security Engineer). This role channels that talent into one coherent direction.
Role Overview
A brand-new, high-impact role with executive backing and a clean canvas. You'll define and stand up the architecture function from the ground up - the target architecture, the ARB process, the Architecture Guild, and the engineering standards that shape how the whole platform gets built. You'll report to the Head of Engineering.
This is influence, not command. The standards land because they reflect what the best engineers already know to be right - shaped with the senior technical leadership, not handed down.
What You'll Own
This role is NOT
Nice to Have
If you've stood up an architecture function on a live, complex platform and you get standards adopted by being right - not by holding the org chart - get in touch for a fast response.
