MEET SIENA Siena is the Agent of Record for consumer brands. One agent that owns the entire customer journey, running on a shared intelligence layer no point tool can replicate. Consumer brands run ten or more disconnected tools to manage their customers. We collapse that stack into a single agent. It started with support, the hardest surface a brand has, and it expands from there: Shopping Agent, Social Agent, Siena working alongside a brand's own operators. One agent across every surface, with shared memory, shared context, and shared tools. Hundreds of brands already run real customer volume on Siena in production. This is built, working, and growing, and we are racing to build what comes next. THE TEAM We are a small, fully distributed, global team. We have built leverage into how we work, which is what lets a team this size move at the speed we do. We hire athletes. Everyone here owns real outcomes, defaults to writing over meetings, communicates with directness, and acts the moment they see something worth acting on. Low ego, high standards, fast clock. If you want to own real problems rather than close tickets, keep reading. WHAT WE’RE LOOKING FOR You're a builder who thrives at the frontier of AI agents, customer experience, and ecommerce.

You thrive working cross-functionally with engineering, design, and go-to-market teams. The consumer-minded builder — you understand what makes products feel good to use. You think about user behavior, ecommerce, purchase patterns, building premium experiences. Maybe you've worked on consumer products, growth teams, or analytics-heavy roles.
