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 developing diverse teams.
Bachelor’s degree in Computer Science, Engineering, Information Technology, or equivalent practical experience.
Integrity, trustworthiness, and follow-through; ability to build partnerships across teams, locations, and disciplines; commitment to engineering and operational excellence.

Responsibilities

Own the 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, including 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.
Partner 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; report on performance, risks, incidents, and delivery commitments.
Use data, retrospectives, and industry practices to improve customer outcomes, platform resilience, team effectiveness, and cost efficiency.
Deliver stable, secure, and resilient production services for time-sensitive financial markets, with lower incident rates, recovery times, manual effort, and deployment risk.

Build clear service ownership, actionable operational metrics, transparent risk reporting, and a high-performing team with strong technical depth and cross-regional collaboration.
