Senior AWS Platform Engineer in London

LondonEngineering – DevX & Platform Engineering /Employee - Permanent /HybridOur StoryHello there. We started our journey back in 2005, building the first ever peer-to-peer lending company. Fast forward to 2020 and we launched Zopa Bank. A bank that listens to what our customers don't like about finance and does the opposite. We're redefining what it feels like to work in finance. Our vision for a new era of banking puts people front and centre — we've built a business that empowers everyone to aim high, every day, to move finance forward. We build the foundations that help engineering teams deliver reliable, secure products with confidence. We are at the beginning of a meaningful transformation: moving from infrastructure that is primarily operated for teams towards a platform that engineers can increasingly use through clear, self-service capabilities. This role will help shape the standards, guardrails and developer experience that make that possible. A Day In The Life: Design and evolve reliable cloud platform capabilities for engineering teams. Improve AWS, Kubernetes, Terraform, CI/CD, monitoring and operational patterns. Help build reusable tooling, guardrails and self-service foundations. Support business-critical services through the shared on-call rota. Strong hands-on AWS platform engineering experience in production environments. Experience with logging and monitoring, networking and protocols, scripting, secrets management and service discovery. Exposure to both AWS and Kubernetes, with sound coding experience. Autonomous delivery and constructive collaboration with application engineers. Experience supporting business-critical services through an on-call rota. Added Bonus: Experience with Honeycomb, OpenTelemetry, Prometheus, Splunk, including SLO-led practices. Pragmatic use of AI-assisted engineering tools to improve quality and productivity. #LI-AP1At Zopa we value flexible ways of working. We value face-to-face collaboration and a good work-life balance. This hybrid role requires you to come to our London office 2-3 days a week. Diversity of experience, perspectives, and backgrounds leads to better products for our customers and a unique company culture for our people. Our approach to AI in interviewsAt Zopa, AI isn't something we're testing out — it's part of how we work every day. As a proud partner of Jobs 2030, we're committed to building AI fluency across our workforce, and we expect Zopians to use AI as part of how they do their jobs. Because of that, we want to be transparent about how we think about AI use during our hiring process. Behavioural and competency-based interviews: please don't use AI. An AI-generated answer can't tell us that. Some technical stages actively welcome AI use, others don't. Your Talent Partner will let you know what's expected at each stage. Where AI is part of the assessment, we'll be interested not just in the outcome, but in how you used it – the tools you chose, your reasoning, and the decisions you made along the way.
