C++ Junior Software Developer, London Heathrow, UK

Want to launch your career as a C++ Junior Developer?

At mthree, we match ambitious graduates with leading global companies across finance, travel, healthcare, and more.

What You’ll Do

You’ll work on large‑scale, mission‑critical software engineering challenges, collaborating closely with Business Analysts and QA teams. Depending on the project, you’ll use either Waterfall or Agile (Scrum) methodologies.

As a Software Development Engineer, you’ll be responsible for the technical design and delivery of product features based on solutions agreed with stakeholders. Because these applications require 24/7 availability, you’ll focus heavily on performance, reliability, and other non‑functional requirements.

• C++
• Unix
• Oracle
• MongoDB
