About the Role
We are hiring a Senior Python Engineer to design, build and run scalable backend systems that power data driven applications. You will develop secure, high performance APIs and microservices, build backend services that serve datasets efficiently, and own data transformation pipelines from ingestion to delivery. This role suits an engineer who writes clean production code and also takes ownership of how that code is tested, deployed and run in production.

- Work with front end teams to integrate user facing features with server side logic
- Write clean, efficient, well documented code that follows coding standards
API Security
- Implement authentication, authorisation and encryption across microservices
- Secure APIs using OAuth 2.0, JWT and API gateways
Data Access and Database Management
- Build backend systems that serve datasets through APIs and other interfaces
- Implement data access layers using ORMs such as SQLAlchemy and Django ORM (models, CRUD, querying, transactions)
- Design and optimise database schemas for relational and NoSQL stores
- Tune query and database performance for fast, reliable data retrieval
Data Transformation and ETL
- Design and maintain ETL pipelines to extract, clean, aggregate and enrich data
- Ensure data integrity, quality and consistency across all transformation processes
- Work with big data and streaming technologies such as Spark, Kafka and Hadoop
Engineering Practices and DevOps
- Build and maintain CI/CD pipelines for automated testing and deployment
- Write unit and integration tests and debug production issues using logging and profiling tools
- Use Git for version control, branching, code reviews and pull requests
- Produce clear technical documentation and contribute to code reviews
