The Role

Delivery & technical leadership

• Drive successful delivery of complex, cross-team infrastructure and platform initiatives by coordinating resources, managing dependencies, and removing blockers
• Define and communicate technical strategy for DevOps and infrastructure - what we own, how we evolve it, and where boundaries sit with product and platform teams
• Ensure the DevOps team works effectively with engineering squads, delivering high-quality, reliable solutions aligned with business and regulatory goals, engaging with Engineering Leads from other teams to foster knowledge sharing, collaborative working and pushing the boundaries forward.
• Build strong relationships across product, engineering, security, and business stakeholders
• Improve delivery processes and engineering practices within infrastructure and operations - CI/CD, release governance, incident response, and operational readiness
• Help the team maintain focus on priorities while managing technical debt, security obligations, and day-to-day operational responsibilities
• Foster collaboration and alignment across teams on shared platform work

Infrastructure, reliability & security

• Lead the evolution of deployment pipelines and system reliability across our monorepos and legacy platform (CircleCI, NX, Docker)
• Guide AWS cloud strategy - hosting, networking, scalability, performance, and cost-efficiency across production environments
• Oversee Infrastructure as Code practices (e.g. Terraform) and ensure environments are consistent, auditable, and secure
• Shape monitoring, observability and alerting across the engineering organisation (e.g. Datadog, CloudWatch) so issues are detected and resolved before customers are impacted4
• Lead incident management practices - on-call, triage, escalation, post-incident reviews, and runbook quality
• Champion security best practices - IAM, WAF, encryption, VPC configuration, and compliance with industry and regulatory standards
• Support capacity planning, cost optimisation, and production readiness for high-risk changes and coordinated cutovers

People & developer experience

• Coach and mentor Operations Engineers in delivery practices, technical leadership, and operational excellence
• Stay hands-on - contributing designs, code, config, and runbooks when that is the fastest way to reduce risk but also know when to step back and allow the team to take the helm
• Improve developer experience: local environments, self-service tooling, documentation, and onboarding for new engineers Contribute to hiring and raising the bar for future Operations Engineers
