Software Engineer - Level III (Full-Stack)

With a company culture rooted in collaboration, expertise and innovation, we aim to promote progress and inspire our clients, employees, investors and communities to achieve their greatest potential. Our work is the catalyst that helps others achieve their goals. In short, We Enable Possibility℠. We're looking for a passionate, detail-oriented Senior Full Stack Engineer who is equally comfortable working across the frontend and backend. You'll contribute to both our user-facing React/Angular applications and our Node.js microservices, helping us build, scale, and maintain the systems that power Thimble's platform — including the external-facing APIs our partners rely on. This role goes beyond feature delivery. You'll help shape the technical strategy of the platform, influence architectural direction, and partner directly with product and growth teams to turn business objectives into engineering outcomes — from improving how customers discover and purchase coverage to scaling the systems behind new products and markets. You thrive in event-driven, distributed architectures and have a strong instinct for writing clean, observable, and resilient code.
