About the Role

We're looking for an experienced Python Developer to support the build and delivery of a Shiny for Python web application hosted within Databricks Apps.

You'll work closely with a Data Science team to refine requirements, build application components, optimise data access, and get the solution production-ready.

Key Responsibilities

• Develop and enhance Shiny for Python UI components (layouts, widgets, visualisations)
• Build and optimise backend data access layers for speed and scalability
• Integrate, package, and deploy applications within Databricks Apps
• Assess data access patterns and advise on whether a PostgreSQL intermediary layer is required
• Configure compute, dependencies, and environments for reliable deployment
• Produce documentation (architecture, app structure, deployment steps)
• Provide knowledge transfer to internal teams

Required Skills & Experience

• Strong hands-on Python development experience
• Proven experience building apps with Shiny for Python
• Good knowledge of Databricks (notebooks, compute, workflows; Apps experience ideal)
• Solid understanding of SQL and PostgreSQL (schema design & performance tuning)
• Familiarity with modern data-engineering patterns (caching, query optimisation, async workflows beneficial)
• Comfortable working in version-controlled environments (Git, CI/CD)
