Senior Software Engineer (Backend)

Super Payments

Super Payments is the only global fintech platform providing 0% processing fees for merchants. Our mission is to use data and AI to make payments free for businesses, so that everyone wins. 

At Super, we are disrupting payments, like Spotify did to music and Robinhood did to trading. We don't make money from transaction fees;  instead, we monetise through value-added services such as lender commissions and FX. Our platform supports multiple payment methods - from traditional cards to direct bank transfers via open banking, as well as Apple Pay, Google Pay, and our own Buy Now Pay Later solution. 

Super has raised $66M from leading investors including Accel, Union Square Ventures and Local Globe (the same investors behind Spotify, Stripe, Monzo) and founded by Samir Desai CBE, co-founder of Funding Circle. 

Already trusted by thousands of businesses and more than 4 million customers, Super is processing at a run rate of £1.5B and growing 4x YOY

Our Values

• Customer obsessed: We only succeed when our customers do.
• Move fast: Build, test and improve quickly. Progress matters more than perfection.
• Own it: Be accountable, solve problems, and make it happen.
• Be open: Act with honesty and respect. Transparency builds trust.
• Win together: Collaboration beats ego every time.

Our Technology

We leverage the latest tools and technologies to create a seamless, customer-centric digital experience. Our core stack is built around Node.js, TypeScript, and NestJS, with a front-end powered by React. We deploy using AWS cloud services and Kubernetes, ensuring scalability and resilience. Infrastructure as Code is fundamental to our approach, and we use Terraform to manage our cloud resources.

Our architecture is cloud-native, event-driven, and distributed, built on Amazon EventBridge and SQS, with services exposed via REST.

We are driven by data science, machine learning, and analytics, using multi-variant testing to personalise user experiences across every digital channel.

However, it’s not just about the technology. We are passionate about continuous delivery, automation, and rapid iteration. Our deployment pipeline is fully automated, covering everything from branching, building, testing, and shipping to monitoring and alerting-allowing us to focus on delivering value to our customers.

Technology is at the heart of our business, and we value diverse perspectives. Bring your ideas, experience, and problem-solving mindset-we’ll navigate obstacles together.
