Own Sentinel's product backlog end-to-end — grooming, prioritization, dependency management, and sprint readiness.
Ensure 100% of items entering a sprint have clearly defined acceptance criteria, eliminating rework caused by scope ambiguity.
Frame backlog items as testable hypotheses where appropriate, keeping delivery connected to Sentinel's PMF learning agenda and ensuring the team knows what success looks like each cycle.
Lead sprint ceremonies — planning, refinement, review, and retrospectives — adapting agile practices pragmatically to what the team actually needs.
Translate strategic direction from the CTO into clear, well-scoped stories, asking the right clarifying questions upfront to prevent rework downstream.
Proactively initiate and structure discovery work every sprint cycle — user feedback synthesis, assumption mapping, delivery retrospectives — and bring evidence-based recommendations to the CTO.
Act as the primary point of contact for requirement clarification during development, unblocking engineers quickly and protecting sprint integrity.
Define, monitor, and report on delivery health KPIs through Jira — including sprint predictability, defect leakage, and cycle time — giving the CTO continuous visibility into Sentinel's delivery quality.
Contribute actively to roadmap and product direction conversations, bringing a grounded, delivery-informed perspective to strategic discussions.
