About the Role

We are looking for a Senior / Staff-level Full Stack Engineer with strong system design expertise and practical experience applying AI tooling in real-world development environments. This is a high-impact role focused on designing and evolving platform architecture, modernising legacy systems, and integrating AI-driven capabilities into both engineering and product workflows.
You will operate with a high degree of autonomy in a fast-paced, low-process environment, contributing not only to technical decisions but also to product direction and commercial outcomes.

This role requires a pragmatic mindset, the ability to work with ambiguity, and a strong sense of ownership in defining and solving complex problems.
