We are looking for a "full-stack" Data Engineer to build the backbone of our data infrastructure and own the end-to-end data lifecycle.

• Quality & Deployment: Implement automated testing frameworks and deploy scalable services using Docker and Kubernetes to ensure operational health.
• Stakeholder Partnership: Act as a strategic partner to Product and Engineering, facilitating data design sessions to optimise how data is ingested and utilised.
• Mentorship & Standards: Raise the bar for technical excellence within the squad through code reviews, design sessions, and documenting best practices.

  • You have extensive experience leading the design of data systems and models.
  • You are an expert in SQL and Python, with a proven ability to independently implement complex, production-ready projects.

• Impact & Scope:
  • You have a track record of leading high-impact initiatives that align with company strategy. You can evaluate proposed work against team goals and provide critical feedback to ensure value delivery.
• Planning & Delivery:
  • You are capable of driving the end-to-end delivery of large-scale features, providing high-quality architectural diagrams and technical documentation.
• Operational Excellence:
  • You have strong experience with modern DevOps practices, including Infrastructure as Code, GitOps, and managing transformation layers at scale.
• Business & Domain Knowledge:
  • You can advise senior stakeholders on applying Data Engineering to solve complex business problems and are comfortable facilitating cross-functional design sessions.
• Leadership & Culture:
  • You role-model UW values by promoting a data-driven culture, mentoring peers, and communicating technical successes and failures clearly to the wider Technology & Product department.
