Aufgaben

• Define and maintain the end-to-end technical vision, roadmap, and lifecycle strategy for the data science workbench offering of the global data platform.
• Gathering requirements and maintaining relationships with current and potential consumer base.
• Ensuring the technical vision and roadmap enables their current and future business ambitions.
• Ensure platform scalability, reliability, performance, and security, embedding non-functional requirements (NFRs), observability, automation, and resilience-by-design principles.
• Lead the prioritisation and delivery of data science workbench related features and capabilities, collaborating with Platform Owner, Scrum Masters, Development Teams, System Architect, and Release Train Engineer to coordinate work across Agile teams.
• Own and drive the community of practices for the data science workbench across the organisation.
• Serve as the primary technical escalation point for incidents, problems, audits, and risk findings related to the data science workbench.
• Establish and monitor SLAs, SLOs, and KPIs; leverage metrics and OKRs to measure platform health, usage, team performance, and business value delivered.
• Drive standardisation, reuse, and simplification across the data science workbench ecosystem to reduce complexity, improve interoperability, and accelerate time-to-market.
