Full Stack Engineer (AI-Focused)

The Role As a Full Stack Engineer at Murmuration, you'll build the client and API products that credit unions and their members use every day. We work in an AI-native way: we expect you to be fluent with AI coding tools, and you'll also help build AI features into the product. 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.
