Senior DevOps Performance Engineering Specialist

Join Our Team as a Senior DevOps Performance Engineering Specialist at LSEG

At LSEG, we’re transforming financial markets through data, technology, and innovation. Our teams build resilient, scalable platforms that power global finance. If you're passionate about performance, reliability, and cloud-native engineering, we invite you to bring your expertise to our collaborative tech hub.

About the Role

We’re seeking a Senior DevOps Performance Engineering Specialist to join the Risk Intelligence team, to help us move the needle on performance, resiliency, and observability initiatives across our cloud-native platforms. You’ll play a key role in ensuring our systems are fast, fault-tolerant, and scalable—especially as we evolve toward microservices and containerized deployments on AWS.

What You’ll Do

• Engineer for Performance & Resilience: Design and execute performance, stress, soak, and chaos tests to validate system behaviour under load and failure conditions.
• Build Observability: Implement and enhance monitoring and alerting using tools like DataDog and AWS CloudWatch, and help us visualise outcomes so we can communicate them efficiently
• Cloud-Native Delivery: Work across AWS, Docker, EKS, and Terraform to help us deploy and manage scalable infrastructure.
• Service Mesh Expertise: Leverage Istio to manage traffic, enforce policies, and improve reliability across microservices.
• Collaborate & Influence: Partner with infrastructure engineers, developers, SREs, and QA engineers to embed performance and resilience into CI/CD pipelines and architecture decisions.
• Drive Continuous Improvement: Champion best practices in performance engineering, observability, and fault tolerance across teams.

What We’re Looking For

• Experience: Proven background in a software or platform engineering discipline; maybe you've been a developer, a curious quality or performance engineer who stretched expectations.... maybe you've been in DevOps, or SRE roles - hands-on experience in cloud-native environments is key.
• Tools & Tech: Strong knowledge of Gatling, JMeter, K6, or similar tools; experience with AWS, Docker, EKS, Terraform, and Istio.
• Observability: Proficiency in APM and monitoring tools
• Chaos & Resilience: Familiarity with chaos engineering principles and tools
• Mindset: Passion for automation, scalability, and building fault-tolerant systems; proactive and collaborative approach to problem-solving.

Why Join Us?

• Work on mission-critical systems in the Risk Intelligence space that prevent bad actors gaining access to global finance.
• Be part of a forward-thinking team embracing modern DevOps and cloud-native practices.
• Access to world-class learning platforms, AWS certifications, and global collaboration opportunities.
