Infrastructure Engineer

About Griffin Hi, we’re Griffin. We’re a fully regulated UK bank that powers the accounts and payments offerings of product-led fintechs and platforms like Uber, Yonder, Prosper, and Sidekick. By doing the heavy lifting behind the scenes, our customers can focus on what they do best - delivering amazing customer experiences. We’ve grown rapidly since our launch in 2024, and today provide the banking backbone behind products in remittance, payroll, wealth, insurance, proptech, payments, neobanking and more. We’re moving into card issuing, stablecoin infrastructure, and agentic finance next as we continue to support the next generation of product-led companies. Learn more about what we do Our culture We believe that smart, motivated, conscientious people thrive in high-trust, high-autonomy environments and have done our best to create such an environment at Griffin. People who thrive here don’t require much hand-holding, and go out of their way to figure out how to contribute in the most valuable way possible. We've been remote-first since we were established in 2017 and we remain so today. Work here is asynchronous and fully flexible - because we want to be a part of your life in a way that helps you to get the most out of both your work and home life. We understand that our culture and ways of working aren’t for everyone, and we’re very intentional about our hiring process as a result. We won't hire people who don’t seem like a strong fit for our core values, even if they're otherwise extremely qualified. Our strong culture has helped us to remain a mission-driven company as we have scaled, and gives our people a clear, explicit operating framework and the space to focus on delivering real value for our customers. Learn more about our culture. The team: Infrastructure sits within the Craft function. We’re a small team of three - two engineers and an engineering manager - who work closely with our CTO and Founder, Allen Rohner . It’s our job to build the foundations that everything else at Griffin runs on: the systems, the tooling, the automation that helps us run a highly resilient and reliable platform and lets other teams ship fast. When we start work, we explore multiple solutions before picking one. We write RFCs, build proof-of-concepts, and run experiments to validate approaches. Once we commit to building something, we care about maintainability more than cleverness, observability more than hoping it works, and scalability over premature optimisation. We take the necessary time to ship quality solutions rather than hitting arbitrary deadlines. Once something goes live, we refactor the rough edges rather than polish what's already working. The opportunity: Day to day, you'll manage the infrastructure the bank runs on - both in the cloud and on our own hardware in third party data centres. This means running FoundationDB clusters and building tooling for hitless upgrades, managing Kubernetes, writing infrastructure as code in Pulumi and CDK,
