We’re supporting a major UK financial services organisation through a significant programme of data engineering modernisation and transformation.

We’re looking for a genuinely Staff-level Data Engineer who combines deep hands-on engineering capability with the technical leadership to challenge existing approaches, shape solutions and raise engineering standards across multiple teams.

This is not a hands-off architecture role. You’ll be expected to shape the thinking, design the solution and get into the code to prove and deliver it.

The role

You’ll work across a major modernisation of the organisation’s data estate, including the transformation and migration of large-scale data pipelines, development of new data products and adoption of modern, AI-assisted engineering practices.

Responsibilities will include:
  • Providing Staff-level technical leadership across complex data engineering initiatives
  • Remaining deeply hands-on with Python, PySpark and Spark
  • Modernising and migrating large-scale data pipelines across AWS
  • Designing and challenging approaches across AWS Glue, Airflow and associated technologies
  • Shaping scalable data architectures, frameworks and engineering patterns
  • Supporting the development of new data products and reusable capabilities
  • Championing AI-assisted development to improve engineering quality and delivery speed
  • Raising engineering standards and capability across multiple teams
What we're looking for
  • Deep hands-on Python/PySpark and Apache Spark expertise
  • Strong AWS data engineering, particularly AWS Glue
  • Strong Apache Airflow experience
  • Experience delivering complex data transformation or modernisation programmes
  • Strong software engineering fundamentals
  • Experience operating at Staff, Principal or Senior Lead Engineer level
  • Ability to independently challenge thinking and shape technical solutions
  • Genuine desire to remain hands-on with code
  • Experience incorporating AI-assisted development tools into engineering workflows
  • Snowflake experience would be beneficial
The sweet spot is someone who can operate across both technical strategy and hands-on delivery — setting the engineering direction while still being capable of building and proving the solution.
