Job description

Join the team behind Price Service—a mission-critical HTTP API powering pricing and promotions across all of Tesco’s channels. From tills to websites and everything in between, our work touches the lives of over 28 million UK shoppers every week, with global reach on the horizon.

We’re building a robust, internet-facing API that runs both in stores and in the cloud, designed to support future innovation at scale. This means solving complex distributed systems challenges, ensuring high availability, and optimizing performance. Concepts like the CAP theorem aren’t just theory here—they’re part of our daily engineering conversations.

Our stack includes Java, Vert.x, RxJava, Groovy, Couchbase, and Kafka, built using Terraform, running in Kubernetes on Azure utilising GitHub Actions pipelines. We follow Agile principles, adapting Kanban and other methodologies to fit the team’s needs.

Collaboration is at the heart of our culture—pair programming is common, and all code is reviewed via GitHub.

Design and implement end-to-end systems using your deep JVM and java ecosystem expertise.

Translate product requirements into well‑structured, maintainable code.

Write test‑driven features and follow the TDD and BDD cycle.

Apply SOLID principles and cohesive design to build scalable software.

Design, build, deploy and maintain the required infrastructure.

Collaborate with product stakeholders to shape and refine features.

Support production systems, resolve incidents, and conduct root cause analysis.

Mentor and support fellow engineers, fostering a culture of continuous learning.

Strong experience with Java 8+.

Hands‑on experience with cloud platforms (Azure, AWS, etc.).

Proficiency with both SQL and NoSQL databases.

Proven ability to scale systems effectively.

Familiarity with Agile methodologies (Scrum, Kanban, Waterfall).

Exposure to reactive programming paradigms.
