C++ Developer - London Stock Exchange Group

Real-Time Software Engineer (C++) - 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 Software Engineer to help evolve our real‑time news collection and distribution platform. 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 mid‑level engineers who thrive as individual contributors and want to grow their expertise in real‑time systems, C++, and cloud‑native development.

As a software engineer in the News team at LSEG, you will write clean, efficient C++ and Python code for both on‑prem and cloud‑hosted environments. Work with structured data formats like XML, JSON, HTML, and XSLT, and learn how they power News industry standards. Collaborate in a scrum team crafting solutions and delivering new features. Be responsible for your code by writing automated tests, participating in code reviews, and supporting production systems. Help automate deployment, upgrades, and maintenance using modern DevOps tools. Occasionally provide on‑call support for critical systems (we keep it reasonable).

What We're Looking For

• Solid experience with C/C++ on Linux and real‑time systems.
• Experience with cloud infrastructure and container orchestration.
• Practical experience in using IP‑based protocols (TCP/IP, UDP, HTTPS, etc).
• Familiarity with unit testing, especially using Google Test.
• Understanding of network protocols and distributed systems.
• Strong problem‑solving skills.
• Ability to work independently and communicate clearly.

Bonus Points

• Hands‑on experience with Python, Google Test framework, GitLab CI/CD, Kubernetes, or Terraform.
• 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, ownership, and teamwork. You'll work in a globally distributed team that supports each other.
• Flexibility: Hybrid work options and a balanced work‑life environment.
