Senior Devops & Automation Engineer

About the roleWe're recruiting a hands-on Senior DevOps & Automation Engineer to own and modernise the pre-production and proving environments of a leading financial services organisation. This is an automation-first role with a strong troubleshooting focus — roughly 50% building and enhancing automation, and 40% diagnosing and resolving complex deployment, environment, and platform issues. You'll be the engineer others escalate to when deployments fail, environments go unstable, or recurring operational issues hit delivery — investigating across applications, middleware, infrastructure, and tooling, finding root cause, and building permanent automated fixes. Pre-production here is treated with the same discipline, governance, and urgency as production. Day to Day Lead investigation of deployment failures and environment issues, troubleshooting across application, middleware, OS, network, and infrastructure layers. Perform deep root-cause analysis and implement permanent corrective actions. Analyse pipeline failures, logs, monitoring data, and infrastructure events; support critical releases and major incidents.

Drive Infrastructure as Code adoption and build reusable, self-service capability so teams can unblock themselves.
