Senior Product Architect / Technical Product Manager for Scalable Commerce Platform (Welkut)

We are building Welkut, a next-generation commerce platform for custom manufacturing, apparel customization, and business procurement. We are seeking an experienced Senior Product Architect or Technical Product Manager to define the technical foundation before software development begins. This engagement focuses on product architecture, system architecture, user workflows, database planning, scalability, API strategy, and long-term product planning. The platform will launch as a single-vendor commerce platform and is intentionally designed to scale into a multi-vendor marketplace in the future. Please do not apply if your primary experience is building WordPress websites or basic eCommerce stores. We are looking for someone with proven experience designing scalable software platforms such as SaaS products, marketplaces, ERP systems, inventory systems, or enterprise web applications. Shortlisted candidates will receive our complete Product Requirements Document (PRD) for review.
