Candidates must be able to demonstrate ownership of major releases, leadership of architecture teams and experience shipping digital products into production. Leadership capability is just as important as technical expertise.

Interview Process

Stage 1: 15-minute introductory discussion Stage 2: 90-minute formal panel interview

Candidates may be asked to deliver a short presentation of up to 5 minutes. No technical test is currently expected.

Summary

This role is best suited to a senior Technical Architecture leader who has built and shipped large-scale digital products, led architecture teams and operated within AWS environments.

The single biggest differentiator will be evidence of user-facing product delivery and ownership of major releases. Recruiters should avoid Enterprise Architecture-focused profiles unless they can demonstrate substantial recent Technical or Solution Architecture leadership experience
