Lead DevOps Engineer - Real Time Platform

FTSE Russell (LSEG) is building the real time platform that powers global index calculation across equity, fixed income, and multi asset markets.

We're looking for a hands on Lead DevOps Engineer to design, secure and operate the cloud infrastructure that keeps this platform always on - supporting low latency, real time workloads at global scale.

This is an individual contributor leadership role, where you'll define infrastructure architecture, raise operational standards, and ensure resilience, security, and observability across a mission critical platform.

This team operates with an AI-first approach. We expect hands on experience with AI development tooling: terminal based agents, AI augmented IDEs, and automated workflows. You are ultimately accountable for production quality, security, and correctness. This means owning infrastructure review, security validation, system observability, and operational guardrails.

• Design and operate cloud infrastructure on AWS to support low latency, always on real time workloads.
• Own infrastructure as code and platform architecture, ensuring secure, scalable and reproducible environments.
• Embed security and resilience by design, including IAM, network controls, encryption, and failover strategies.
• Build observability and operational excellence, enabling fast detection and resolution of incidents.
• Enable safe, fast delivery through CI/CD and automation, partnering closely with engineering teams.

• Infrastructure as Code: Terraform, AWS CloudFormation, AWS CDK.
• Cloud: AWS (Lambda, API Gateway, S3, SQS, SNS, Aurora, VPC, IAM, CloudFront, WAF, and others as required).
• CI/CD: GitLab CI, Terraform, AWS CLI.
• Observability: CloudWatch, Datadog, OpenTelemetry
• Languages: Python, Bash, TypeScript.
• AI Development: Agentic AI tooling (e.g. GitHub Copilot, Claude Code).

• Strong experience designing and operating cloud native infrastructure on AWS.
• Deep expertise in infrastructure as code (Terraform) at scale.
• Proven ability to build and run resilient, highly available systems.
• Strong understanding of cloud security principles, with hands on implementation.
• Experience with observability and incident response in production systems.
• Ability to lead through technical standards and delivery, not just tooling.

• Experience supporting low latency or real time systems.
• Exposure to financial services or market data platforms.
• Practical experience with AI assisted engineering workflows.
