•Measurable reductions in incidents, recovery time, manual effort and deployment risk.
•Consistent production-readiness, service-acceptance and operational-governance standards.
•Modern, reusable delivery patterns for applications and infrastructure across hybrid environments.
•Clear service ownership, actionable operational metrics and transparent risk reporting.
•A high-performing team with strong technical depth, customer focus and effective cross-regional collaboration.
What You will Bring
•Proven experience leading DevOps, Site Reliability Engineering, production engineering or application support teams in a complex, regulated or high-availability environment.
•Strong operational leadership across incident, problem, change, release, capacity, availability and continuity management.
•Hands-on understanding of Linux/Unix platforms, networking, databases, middleware, cloud services and distributed application architectures.
•Demonstrated delivery of CI/CD, infrastructure as code, configuration management, automated testing and secure software-delivery practices.
•Experience using observability and operational tooling to improve service health and reduce mean time to detect and recover.
•Ability to assess technical and operational risk, prioritise remediation and communicate clearly with senior technical and business stakeholders.
•Strong people-management skills, including hiring, coaching, performance management, workforce planning and development of diverse teams.
•Bachelor's degree in Computer Science, Engineering, Information Technology or equivalent practical experience.
•Financial markets, trading-platform or market-infrastructure experience is preferred; strong candidates from other high-availability technology environments are also encouraged to apply.
•Relevant experience may include AWS, Linux/Unix, Kubernetes, Docker, Terraform, Ansible, Git-based source control, Jenkins or comparable CI/CD platforms, Python, Bash, PowerShell, Kafka, SQL/Oracle, Control-M, Datadog or similar observability platforms, Jira and Confluence.
