Job description

Senior Software Engineer – News Engineering @ LSEG

Help us shape the future of real‑time news delivery and join a team powering the heartbeat of global information! LSEG’s News Engineering group is looking for a Senior Software Engineer to help evolve our News platform, delivering enriched breaking news to customers worldwide in sub‑second time. If you're motivated by high-performance systems, real-world impact, and incorporating modern engineering practices in a dynamic and forward‑thinking environment, this is your opportunity.

This role is ideal for engineers who thrive as individual contributors and can lead a scrum team. You’ll deepen your expertise in low‑latency, high‑throughput systems and have clear paths to expanding your career to technical leadership, architecture, reliability, or applied ML for news analytics.

As a senior software engineer in the News team at LSEG, you will build and evolve services, primarily in Java and Python, with a strong emphasis on performance, observability, and continuous improvement in a cloud‑native environment. We encourage pragmatic experimentation with new tools, libraries, and approaches when they improve reliability, performance, or developer experience. Learn how structured data and News industry standards enable fast, reliable news delivery while simplifying problems for customers. Collaborate in a scrum team, crafting solutions and delivering new features. Own the design and delivery of critical services, from architecture decisions through to production support, with autonomy to influence technical direction. Help automate deployment, upgrades, and maintenance using modern DevOps techniques. Participate in a well‑structured on‑call rotation focused on sustainability, automation, and preventing repeat incidents — not heroics.

What We’re Looking For

• Solid experience with Java and Python on Linux and real‑time systems.
• Practical experience using IP‑based protocols (TCP/IP, UDP, HTTPS, etc).
• Familiarity with unit testing and test‑driven development.
• Understanding of search technology such as Elasticsearch.
• Experience with cloud infrastructure and container orchestration.
• Strong problem‑solving skills.
• Ability to work independently and communicate clearly.

Bonus Points

• Hands‑on experience with GitLab CI/CD, Kubernetes, or Terraform.
• Experience with GitHub Copilot to aid in the engineering process.
• Knowledge of NewsMLG2 or similar standards and experience implementing a standard format at speed.

Why Join Us

• Impact: Your work helps deliver critical news to millions in real time.
• Growth: Learn from expert engineers and expand your skills across cloud, data, and resilient systems.
• Culture: We value curiosity over dogma, ownership over handoffs, and pragmatism over perfection. You’ll work in a globally distributed team that supports each other.
• Flexibility: Hybrid work options and a balanced work‑life environment.
