About the role

Key responsibilities & impact

Design and implement new data capabilities, including large-scale data ingestion, transformation pipelines, robust high-performance APIs, and consumers for high-frequency event streams.
Contribute to the development of the proprietary data platform and help evolve it towards a data mesh architecture for the enterprise.
Build solutions using the standard technology stack: Python, Linux via WSL, PostgreSQL, SQL Server, Databricks, and cloud infrastructure spanning Azure and AWS.
Develop advanced mechanisms for data ingestion, transformation, and mass-parallel orchestration of network IO.
Model data for operational and analytical purposes in collaboration with your team, other engineering teams, and analytical data customers.
Work with infrastructure teams to maintain Infrastructure as Code and deliver valuable features for the engineering platform.
Improve data quality across the estate by defining and acting on indicators such as completeness, accuracy, reliability, and usability.
Evaluate potential new data sources for specific applications, assessing their completeness, accuracy, and business value.
Contribute to quality automation in CI/CD processes, optimising for a bug-free release cadence and a positive developer experience.
Support test automation through platform enhancements and additional automated tests.
Maintain clear technical documentation, starting with well-documented code and extending to materials for technical and non-technical audiences.
Participate in a pairing-first development team by sharing expertise, learning from colleagues, and contributing to an open engineering culture.
Mentor and coach less experienced engineers through design discussions, code reviews, and practical knowledge sharing.
Assess application security and API quality to ensure solutions comply with relevant application security and API standards.
