Software Engineer – Engineer II (Level 3) – Backend / Platform
At Fluro, we’re on a mission to create a lasting, positive change in the credit industry. As a fast-growing fintech team, we’re building pioneering, fair and accessible digital finance products designed for the UK market—driven by a belief that finance can be a force for good. From our brand to our environmental footprint, we care about the details and do things with purpose.
We foster a highly collaborative culture that values both collective progress and individual autonomy. Whether you’re an experimenter or strategic thinker, you’ll find the freedom to work in a way that suits you best, while making real impact. Innovation is central to how we operate, and we’re not afraid to try new things (and sometimes fail) in pursuit of better solutions.
Fluro is proud to be an equal opportunities employer. We’re committed to building for good—for all people. That means listening more than speaking, and creating space for diverse experiences, backgrounds, and voices to shape our future. If you’re passionate about making finance fairer, smarter, and more human, we’d love to hear from you.
Role
We’re looking for a talented Software Engineer to join our engineering team remotely. You’ll work on the services and APIs that power Fluro’s lending platform: the systems behind our customers’ loans and financial products. Our backend is built on AWS, with services written in Kotlin and PHP, including the GraphQL backend that serves our mobile app. Sitting within the product and engineering team, you’ll collaborate closely with other backend engineers, our mobile developers and product managers to deliver a secure, reliable and scalable platform.
This is an Engineer II (Level 3) role.
You’ll deliver work without supervision from senior team members, taking full ownership of well-scoped projects end-to-end – from gathering requirements through to validating outcomes. You’ll make sound technical decisions within your domain, balance delivery against long-term sustainability, and support the growth of more junior colleagues.
