Descripción del puesto

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.

The Role You own the commercial relationship for Siena's highest-value brands: renewals, expansion, executive trust, and knowing your accounts better than anyone. A deployment strategist owns product outcomes for the same accounts — together you're the Siena pod. You hold your accounts to specific, measurable commercial outcomes: net dollar retention, expansion, and the strength of the executive relationship. You own our Growth and Strategic segment accounts - not the full customer book - and work at the intersection of customer, sales, and your deployment strategist. You'll lead commercial reviews, executive account mapping, and account planning, and run in-person workshops, account visits, and QBRs with your accounts. Expect moderate travel. What Success Looks Like You are accountable for: Net dollar retention (NDR) of your book Expansi
