Here at Data Idols, we’re working with an innovative technology business that is scaling a cutting‑edge AI‑powered platform used by enterprise clients globally. As the platform continues to grow, they’re looking for a Backend Senior Software Engineer to play a key role in shaping its future architecture, scalability and technical direction.

This is an opportunity to join a high‑performing engineering team where you’ll have genuine influence over architecture, technology decisions, product direction and engineering standards.

As a Backend Senior Software Engineer, you’ll take ownership of key platform components from design through to deployment, optimisation and ongoing support. Working within a modern cloud‑native environment, you’ll help design, build and scale the backend services that power an AI‑driven platform entering a significant growth phase and supporting an increasingly large enterprise customer base.

You’ll be solving complex engineering challenges around scalability, performance and reliability, designing distributed systems and building resilient enterprise‑grade software that forms the foundation of the platform.

This is a highly visible role where you’ll collaborate closely with product and engineering leadership to shape technical roadmaps, influence architecture decisions and contribute to the long‑term evolution of the platform. You’ll be responsible for delivering high‑quality, resilient software, improving engineering processes and tooling, and driving best practice across development, testing, deployment and monitoring.
