• Cube is hiring a Senior Backend Engineer to join our Engineering team. • You’ll partner closely with Engineering, Product, Marketing, and Customer Success, and you’ll report to one of our Engineering Managers. • This role carries meaningful ownership and influence across the team and the product. • Our mission is to create an extremely simple and intuitive product in an industry—Financial Planning & Analysis (FP&A)—that is inherently complex. • We’re looking for a senior engineer who thrives in the middle of complex systems—not just greenfield projects—and who takes pride in evolving large, long-lived codebases under real business constraints.

We are looking for Software Engineers that shares the same values of pragmatism, professionalism and transparency as us to join our team in Brazil. You'd be utilising your expertise with both clients and also internally - helping to shape Codurance, and being involved in coaching and mentoring across the company. We support our clients in many ways and you will have the opportunity to work on a wide range of different internal and client projects. Perhaps you’ll work on a greenfield project for a startup, or helping to build a mission-critical system for a large enterprise client. Perhaps you’ll work as an embedded craftsperson, working within our client's existing development to help them to get better at writing their own software. Or maybe you're more interested in helping to introduce the values of Software Craftsmanship and Extreme Programming practices to an organisation through coaching & mentoring.
