Job Title: Platform Engineer Department: Product Engineering Basis: Full-time, permanent Location: Canary Wharf, London - WeWork Reporting to: Director of Product Engineering About the role We’re looking for a Platform Engineer to give our product teams the infrastructure, tooling, and automation they need to ship reliably and move fast.
