Senior Product Designer — San Mateo, CA

For sharp problem solvers who like hard, messy B2B workflows: design how AI agents and real people share work.

Our client is a venture-backed AI company in the construction tech space, modernizing how construction materials get bought and sold. Hundreds of distributors and sales agencies already run their day-to-day work on the platform, from sourcing products to building quotes to managing projects.

This isn’t a “make the screens pretty” role. WzP Dp is already live and doing real work for paying customers: reading product documents, matching products, and powering search. Next up are AI agents that take on entire tasks, like putting together a quote or handling an incoming order, while a person reviews and signs off. You’ll design that handoff: what the agent does on its own, where a person steps in, and how users can quickly confirm the result is right.

yxh team is looking for people who think hard and adapt fast. If you’ve designed complex B2B products, you’re comfortable when the problem isn’t fully defined yet, and you build working prototypes instead of static mockups, you’ll fit right in.
