• 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.
