The Inventory team supports sellers with managing their merchandise on Whatnot and representing it as accurately as possible so they can reach more buyers. They strive to do this in the fewest steps possible so sellers can get back to what they do best: selling and engaging with their community. Merchant Tooling, a subteam of Inventory, supports the needs of our largest and most complicated sellers. Whatnot is committed to helping our sellers turn their passion into a business, and as they grow their business with us their needs evolve. We build the systems to be able to support external and internal tooling for sellers with needs at scale, such as integrations to other e-commerce platforms, WMS, ERPs, and accounting software.
As part of the Merchant Tooling team, you will design and build large-scale, highly reliable systems that support our largest and most complex customers. Your work will focus on:
Delivering seamless, bi-directional data synchronization across marketplace, ecommerce, ERP, and other enterprise systems, ensuring accuracy, consistency, and low-latency data flow.
Partnering closely with cross-functional stakeholders—including Product, Inventory, Operations, and external partners—to understand business needs, translate them into technical requirements, and drive aligned outcomes.
Architecting and evolving enterprise-grade systems that remain intuitive for developers, easy to iterate on, and capable of supporting rapid product growth.
Contributing to and accelerating the broader Inventory team roadmap, providing technical insight, proactive problem-solving, and hands-on implementation support.
At its core, this team is responsible for building solutions that power how larger enterprise-level sellers interface with our platform. Your contributions will directly shape the foundation that enables these sellers to onboard, operate, and scale successfully.
We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our Los Angeles, New York, San Francisco or Seattle hub.
