Luke Fieldsend is a Director of Engineering based in London with 10 years of experience building and scaling engineering organisations and high-availability systems. He has led transformations from hands-on architecture and security to people processes—most recently rebuilding CoinTracker’s data and infrastructure domain and driving Policy Expert’s tech scale-up from a tiny team into a 110‑person function with dramatically improved reliability and deployment velocity. Luke combines deep DevOps and security roots with product-minded platform leadership, delivering cloud migrations, data warehouses, and MLOps pipelines while cutting attrition and contractor dependence. He’s pragmatic about hiring and succession planning, having promoted multiple technical managers and standardised hiring processes. Known for turning chaotic domains into disciplined, measurable engineering practices, he now leads engineering at OakNorth where he focuses on teams that can sustain work at scale.
