We’re looking for a scrappy backend engineer based in London to join our fintech startup at the ground floor. This role is a good fit for those who are excited about independence, impact, and contributing to the battle against scams and financial crime. If this sounds like a match for you, read on to learn more ⬇️

About Tunic Pay
We’re on a mission to rid the world of scams. Last year, consumers reported over 200k scams in the UK alone, and it’s likely that many more went unreported. At Tunic Pay, we’re rearchitecting payments infrastructure to bring that number to 0 by giving unprecedented insight into and control of each transaction. Our core infrastructure is building Payment Intelligence, and eventually the governance for real-time payments.

We are a super early & super fortunate fintech startup — to give you a sense of just how early, we closed our seed round last November , and we find ourselves in the amazing opportunity of working with some of the largest banks in the UK.

We believe in strong in-person collaboration so are requiring 3+ days a week jamming together in our London office (Farringdon).

Here are some thoughts on who would be successful in the role. We know we won’t be able to assess these from your CV, but our interview process will be designed around them: • Scrappiness: You can autonomously drive value without the comforts of existing infrastructure, developer tooling, and so on. • Systems: You understand how to build fault-tolerant, large-scale distributed systems. • Breadth: You are unafraid of jumping into new terrain; you have a propensity for picking up new tools and technologies or perhaps some experience in an adjacent role like data engineering or infrastructure. • Abstraction: You enjoy getting stuck into high level architectural design discussions as much as low-level implementation and debugging.

Some hard skills we’d value • Languages: Modern backend languages such as Java / Scala / Go / Python / Rust. • Architecture: Proven track record architecting and maintaining fault-tolerant distributed systems. • Data: Experience working in sensitive data contexts and good understanding of data governance practices and privacy concerns. • Infrastructure: You’ve worked with cloud technologies (e.g. Docker, Kubernetes, Helm, Terraform), and providers (e.g. AWS, GCP) in the past. • Years of experience: 7 or more. We’re looking for professionals who can structure their own work, be a strong technical voice for the team, and balance strategic thinking with getting their hands dirty. But we’re not overly strict on this one. • Stage of experience: We value people who have worked in early stage companies and demonstrate fluency with ongoing speed: precision tradeoffs and iterativeness. • Industry: We’re building on top of technical payments infrastructure so prior experience in fintech or banking is a plus, but experience building large-scale systems in any sensitive data context will get you off on the right foot.

Stuff you’d do • Build robust, well-tested, performant backend services that integrate with our customers’ systems to drive down scams. • Design intuitive APIs for seamless integration and scalability. • Understand and drive adherence to best practices for security, data management, and privacy. • Contribute to crucial early technical decision-making: architecture, technical standards, tools, etc. • Dive into any and all parts of the stack alongside the backend as needed, e.g. infrastructure, data, front-end. • Participate in effective code reviews (on both sides of the table!). • Stay up-to-date with industry best practices & technology, including finding ways to be efficient with genAI tooling.
