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.

• 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.
• Share knowledge across the wider engineering community.
• Prototype and evaluate new tools and technologies.

• 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.
