Mark Siedle is a Senior Engineering Manager with 11 years of professional experience building developer-centric platforms and product features at Octopus Deploy. He leads Backend and Frontend Foundations teams focused on developer experience, stability, and scalable platform work, and previously drove the Config-as-Code initiative that enabled seamless Git/Database persistence. Mark blends hands-on engineering—spanning backend .NET systems and React front-ends—with a practitioner’s focus on usability, shipping features like Runbooks and auto-deploy that became core product differentiators. He has a track record of creating API-first architectures, performance optimizations, and security-conscious systems for high-traffic applications. Based in Queensland, Australia, he pairs technical leadership with customer-driven research through usability sessions and explores interoperable healthcare data via personal FHIR projects. Outside work he’s equally likely to be planting fruit trees, playing PUBG, or watching Dragon Ball.
