Tech Lead - Core Platform

The Role As a Tech Lead at Murmuration, you'll take ownership of the core platform build that will service the credit unions and their members. Working in a small team, you will mentor and support your fellow engineers to maximise the quality of the platform whilst working as efficiently as possible. We work in an AI-first way: we expect you to be fluent with AI coding tools and have enough confidence in your own abilities to support and develop the team in working this way. Reporting to the Chief Technology Officer, you'll be one of the first engineers here, with a real say in the product and how it's built. About Murmuration Murmuration is a new technology company building the core platform that credit unions run on. We provide the software, payments, and data infrastructure that lets a credit union offer its members modern digital banking without having to build or run the technology itself. Credit unions are member-owned and rooted in their communities, but many still operate on systems that are decades old, which limits what they can offer their members. We're building the alternative. We're a new company, putting our platform and our first engineering team in place now, with the backing of an established group. For people who join early, that means a real say in the product, the architecture, and how the company works. What you'll be doing
