Software Engineer

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.
