Job description

An experienced Senior DevOps engineer is required to join the Technology Operations (TTO) team within LSEG Markets & Risk Intelligence. You will be part of a team that will help us build the future of financial services on blockchain technology. The team is responsible for the delivery and support of production environments which are typically housed within Azure, as well as integrating software changes into the enterprise environment as part of ongoing project work. The role includes participation in an on-call rota to ensure coverage during business hours, with plans to expand support coverage as the business scales. Occasional weekend work may be required to support release testing and deployment activities. DMI (Digital Markets Infrastructure) is an ambitious project: large-scale, complex and uses a range of blockchain architecture patterns, with numerous stakeholders (internal and external) and use cases. The work is focussed on the tokenization of financial instruments, i.e. as digital assets. We seek candidates with a curiosity about financial markets with experience working on large projects. This is a chance to work on an ambitious project backed by the influential reach of the London Stock Exchange Group. This opportunity sits within a true “build it, you run it” team, working on a cloud‑native product. The role offers hands‑on ownership across the full lifecycle, from building and evolving the platform through to running and supporting it in production. You’ll work closely with our development colleagues in the UK and Bucharest through agile sprints, contributing to design decisions, automation, reliability, and the continuous improvement of a critical trading service. Ensuring the availability of this service will be a key responsibility.

What you'll be doing:

• Implement, handle, and optimise Cloud deployments and automations of DMI applications.
• Develop and run container orchestration solutions using Kubernetes and similar technologies.
• Implement, maintain, and optimise containerization for DMI services (e.g. via Docker).
• Automate infrastructure provisioning and scaling (e.g. Terraform).
• Integrate security protocols into the DevOps lifecycle, ensuring adaptability against vulnerabilities.
• Partner with software engineers, QA, and other teams to ensure efficient deployment, monitoring, and maintenance of applications.
• Keep up to date with the latest industry trends, tools, and guidelines in DevOps and cloud infrastructure.

What you'll bring:

• Computer science, software engineering, or relevant technical background required.
• 5 + years of professional experience in DevOps and infrastructure management.
• 5+ years of specific experience with Cloud platforms (AWS/Azure/GCP).
• Proficient in Kubernetes, Docker, and Terraform.
• Experience with the Azure cloud platform, handling workloads, provisioning & deployments.
• Deep knowledge of security standards in cloud and DevOps contexts.
• Proven knowledge of scaling, availability and cloud resiliency models, patterns and designs.
• Ability to anticipate potential infrastructure challenges and provide innovative solutions.
• Curiosity about new technologies and continuous improvement methodologies.
• Familiarity with blockchain/DLT desirable.
