• Engineering Alignment: Collaborate with Platform Architects, DevOps, and Data Engineering teams to define project scope, secure resources, and manage technical dependencies.
• Reliability & Compliance: Ensure all infrastructure and data projects adhere to security protocols, regulatory requirements, and internal reliability targets.

• Agile Proficiency: Apply expert knowledge of Scrum and Kanban within an engineering context, managing sprint planning, backlog refinement, and continuous delivery practices.
• System Integration: Also apply your organisational and management skills to large scale, fixed time system integration programs in a way that promotes transparency and minimises delivery risk.
• Reporting: Provide transparent, data-driven reporting using Jira dashboards and quantifiable metrics, clearly showing the status of both internal delivery and external client dependencies.
• Blocker Resolution: Facilitate technical and architectural decisions, acting as the primary point of contact to resolve critical technical roadblocks for both internal and client teams.

Team / Relationship Management: Form strong working relationships with clients and internal teams. Effectively operate in a matrix team structure. Lead and facilitate meetings and ceremonies.
