• A collaborative approach to multidisciplinary product delivery.

Requirements

• Strong Python skills, including building maintainable production services and REST APIs.
• Experience reviewing, refactoring and productionising existing code so that it runs reliably in a pipeline.
• Good testing discipline across application and data components, including test-driven development.
• Understanding of clean design principles such as SOLID.
• Experience with CI/CD, version control and containerisation, ideally with on-demand or temporary environments.
• Experience with a major cloud platform, ideally Microsoft Azure.
• Understanding of security, scalability and observability for production services.
• Proficiency with both SQL and NoSQL databases.
• Experience integrating services with data pipelines, APIs and existing applications.
• Exposure to integrating LLM-based or other AI features into backend services, including validation of model outputs.

Benefits
