• Partner with technical architects, data architects, Snowflake resources, integration resources, developers, QA teams, and offshore delivery teams to ensure business requirements are properly understood and implemented.
• Manage the overall delivery plan, including scope, priorities, milestones, risks, issues, dependencies, action items, and status reporting.
• Provide leadership and day-to-day direction to offshore technical resources located in India, ensuring work is aligned to client priorities and delivery expectations.
• Review deliverables from business analysts, developers, data architects, and technical teams to ensure alignment with business objectives.
• Support backlog creation, backlog grooming, sprint planning, solution validation, UAT planning, and release readiness.
• Lead client-facing status meetings, working sessions, design reviews, demos, and executive-level updates as needed.
• Identify business and delivery risks early and work with Seine Client leadership and stakeholders to define mitigation plans.

• Ensure that business requirements are traceable through design, build, testing, deployment, and post-production stabilization.
• Help define adoption, training, change management, and operational readiness needs for the modernized tax platform.
• Support the transition from legacy, manual, spreadsheet-driven, or fragmented tax processes to a more automated, data-driven, scalable platform model.
