- 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.

- Acts with integrity, earns trust and follows through on commitments.
- Builds partnerships across teams, locations and disciplines.
- Sets a high bar for engineering and operational excellence.
