Collaboration & Delivery

· Work closely with Product Manager, UX, and Customer Success to translate business and customer needs into technical solutions.

· Participate in agile development processes including sprint planning, estimation, and retrospectives.

· Help build solutions that reduce manual delivery and support through increased self-service capabilities in the product.

Key Qualifications
