Position Purpose:

As a Technical Business Analyst, you will be an integral part of our growing eCommerce organization and support the functional analysis and delivery of our Commerce Services platform.

You will work closely with the Product Owner to analyze, clarify, and document requirements for commerce domain services supporting B2B and B2C storefronts, as well as internal sales tools. You will collaborate with engineers, Tech Leads, Architects, QA specialists, UX specialists, and business stakeholders to ensure business processes, system behavior, integrations, and user experiences are clearly understood.

You will also analyze API and system-integration requirements and document dependencies across systems such as ERP integrations, PIM, search platforms, and other components of the commerce ecosystem.

Throughout delivery, you will provide functional clarification to development and QA teams, support defect analysis, validate delivered functionality against agreed requirements, and assist with business acceptance activities.
