You work closely with engineering, commercial, and domain teams to ensure these platform investments unlock measurable value across the business.
Key Accountabilities & Responsibilities
- Own the strategy, vision and roadmap for both the API-as-a-product programme — engaging stakeholders across engineering, commercial, and customer teams to define, validate and iterate it continuously.
- Define and drive a consistent framework for API definition and management across three tiers: internal domain APIs, cross-NSEC internal APIs, and external APIs for customers, brokers, and third parties.
- Make evidence-based prioritisation decisions, estimating effort and value of roadmap items using AI-powered estimation tools, and communicating trade-offs transparently with stakeholders.
- Define and track key product outcomes — implementing dashboards for real-time performance visibility and using data to drive continuous improvement.
