James King is a Staff Software Engineer with 14 years’ experience building reliable, high-throughput services and customer-facing applications across fintech, foodtech, and communications. Currently leading engineering efforts on Monzo’s Flex product, he specializes in shipping product-focused features at scale and turning complex borrowing workflows into dependable, user-centric systems. Previously he drove agent tooling and Care platform delivery at Deliveroo and led full-stack engineering and InfoSec responsibilities at DVELP, blending hands-on coding with technical leadership and operational rigor. He has a strong backend pedigree (including notable contributions extending the Facepunch.Steamworks C# Steamworks integration) and a history of modernizing stacks from legacy systems to cloud-native architectures. Based in South Kesteven, England, James combines pragmatic engineering with clear communication and a penchant for seeing projects through from scoping to graduation. Outside work he’s oddly passionate about Coca-Cola, bacon, and losing spectacularly at boardgames — a reminder he brings humility and personality to high-performing teams.
