ROLE SUMMARY:

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.

AI-First Engineering 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.

WHAT YOU'LL DO:

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.

Tech Stack

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).

WHAT YOU'LL BRING:

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.

Nice to Have:

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

How We Work

The Real Time team builds and operates the platform that calculates, manages and distributes FTSE Russell's real-time indices to the global financial ecosystem. We foster a culture of engineering excellence, solving real-world problems with purpose and ambition. We're looking for skilled and passionate engineers to drive the future of modern solutions working with leading AI development tools.

Build with purpose. Start with why. Define the problem before reaching for a solution.
Customer driven. Work backwards from client needs and build products to address real-world problems.
Technically courageous. Go beyond your comfort zone and push boundaries to deliver excellence.
Learn and be curious. Continuously seek feedback, learn in formal and informal settings, actively share knowledge.
Act as owners. Operate as though it is your business. Make thoughtful trade-offs and deliver long-term value.
Lead with data. Validate assumptions, stay close to the details, act decisively.
Build responsibly, deliver incrementally. Look for the small opportunities and milestones to build ambitious solutions.
AI-native by default. Use AI tooling as a force multiplier, frame problems clearly, validate continually, and own the output.
