Responsibilities
• Be the owner and go-to expert for the reliability and performance of our production systems • Lead database migrations and rearchitecture projects across teams, from planning and risk assessment through cutover, with minimal disruption to customers • Scale our infrastructure and data processing pipelines to keep pace with growing data volumes and throughput • Build self-service tools and automation that let engineers deploy, test and debug on their own • Maintain and improve staging and development environments, deployment automation and testing infrastructure • Improve observability across our systems, using AI-assisted workflows to cut manual investigation and repetitive operational work • Respond to production incidents and lead post-incident reviews that result in lasting fixes • Collaborate with Information Security, Product and the wider engineering team to keep our systems secure and flag feasibility and scalability risks early • Set and meet reliability and performance targets for the platform • You know our production architecture, data layer and deployment pipeline well enough to make changes safely, and you have shipped improvements to production. • You have assessed our current database setup and agreed a plan with engineering leadership for the first major migration or rearchitecture, including risks, sequencing and rollback. • You have delivered at least one reliability or observability improvement that other teams notice, such as fixing a noisy alert or replacing a recurring manual request with a self-service tool. • After one year • You have led at least one major database migration or rearchitecture to completion without unplanned customer-facing downtime. • Our systems handle higher data volumes and pipeline throughput, and reliability and performance are tracked against agreed targets. • Engineers across CreativeX use self-service tooling you built to deploy, test or debug, and wait less on the platform team. • At CreativeX, we encourage applicants of all backgrounds and identities to apply for roles that align with their own interests and career trajectory. If you fit the description above and see yourself in this role, we would love to see your application!
