DevOps & Application Services Manager

About the Role

We are looking for an experienced DevOps & Application Services Manager to lead a St. Louis-based team supporting highly available, low-latency trading and market infrastructure services. This role combines people leadership, production ownership, and engineering discipline to improve service resilience, deployment safety, observability, and operational efficiency across on-premises and cloud environments. You will work with global engineering, product, infrastructure, cyber, risk, and business teams to ensure critical services are secure, reliable, and ready to scale.

Key Responsibilities

• Manage, coach, and grow DevOps and application support engineers; set clear objectives, build capability, support succession planning, and create an inclusive, accountable culture.
• Be accountable for availability, performance, capacity, and recoverability of assigned trading and application services, using service-level objectives and operational metrics to drive outcomes.
• Lead incident, problem, change, release, and event-management practices; coordinate major-incident response, stakeholder communications, root-cause analysis, and corrective actions.
• Advance CI/CD, infrastructure as code, configuration management, automated testing, deployment controls, and repeatable environment provisioning.
• Improve monitoring, alerting, logging, tracing, dashboards, and automated remediation; reduce operational toil and recurring failure demand.
• Maintain disaster-recovery readiness, business-continuity controls, security compliance, vulnerability remediation, audit evidence, and operational risk actions.
• Work with global product and engineering teams to ensure new services are supportable, production-ready, and aligned with enterprise architecture and technology standards.
• Manage priorities, resources, technical debt, service improvements, and dependencies; provide clear reporting on performance, risks, incidents, and delivery commitments.
• Use data, retrospectives, and industry practices to improve customer outcomes, platform resilience, team effectiveness, and cost efficiency.

What You Will Deliver

• Stable, secure, and resilient production services supporting time-sensitive financial markets.
• 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.

Requirements & Tech Stack

• 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, prioritize 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.
• 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.
• Embraces change, challenges constructively, and turns ideas into measurable outcomes.
• Communicates calmly and decisively during high-pressure events.
• Creates clarity, enables ownership, and develops others.

Qualifications

• Bachelor’s degree in Computer Science, Engineering, Information Technology, or equivalent practical experience.

Role Details

• This role is based in St. Louis and follows LSEG’s hybrid-working approach, with the team’s pattern agreed according to business and operational needs.
• Participation in an out-of-hours management escalation rota is expected.
• Planned weekend or evening support may be required for releases, resilience testing, or major service events.
• The role works across US, UK, EMEA, and Asia-Pacific time zones; occasional travel may be required.
