Job description

Our mission is to power free payments for businesses and more rewarding shopping for customers so that everyone wins. By removing payment fees and passing savings back to customers, we are disrupting the payments industry while helping businesses increase sales and loyalty.

With Buy Now, Pay Later (BNPL) free for merchants and 0% card payment processing, Super gives businesses a powerful way to reduce costs, grow sales, and reward customers.

Already trusted by thousands of businesses and more than 2 million customers, Super is growing fast, supported by leading investors including Accel, Union Square Ventures and LocalGlobe, and led by Samir Desai, founder and former CEO of Funding Circle.

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.

What You’ll Be Doing

• Working on the design and evolution of our B2B API, personalisation and payments infrastructure.
• Collaborating with UX and product teams in discovery, ideation, and problem‑solving.
• Contributing to engineering‑wide initiatives, participating in technical discussions, architecture decisions, and best practice sharing.
• Developing a deep understanding of our business, customers, and domain—applying your judgement to make autonomous decisions.
• Supporting the growth of our engineering community, sharing knowledge through pairing, talks, and external speaking opportunities.

We’d love to hear from you if you:

• Have at least 5 years of experience in software engineering.
• Have worked in Financial Services in areas like payments, wealth management, or banking.
• Or have experience in payments infrastructure (e.g., eCommerce) or at a high‑volume transaction scale‑up (e.g., betting, gaming, or streaming).
• Have a delivery‑focused mindset, using agile practices to drive team success.
• Bring experience with a variety of programming languages.
• Are willing to work with Node.js, TypeScript, NestJS, and AWS cloud technologies.
• Have experience designing and provisioning cloud‑based infrastructure, using Infrastructure as Code (Terraform).
• Ideally, have worked with Kubernetes and understand the fundamentals of containerised deployments.
• Have built and supported publicly accessible REST APIs.
• Understand application development, continuous delivery, test automation, and security within distributed services.
• Have a track record of improving code quality, performance, stability, and scalability.
• Are comfortable working in a fast‑paced, evolving start‑up environment.
• Can work independently, tackling ambiguous challenges and driving solutions forward.

Our Benefits

• Tax advantage Share Options
• Choice of Laptop – MacBook or Windows
• Work from home set up
• Contributory Pension Scheme
• Team lunch and social evenings
• Your birthday off, plus one Revival day
