Head of Growth

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 brands 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.

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 people who thrive here are curious customer-obsessed and take ownership without being asked. They fix problems first and explain later. Theyre direct about feedbackboth giving and receiving itbecause they care more about getting things right than being polite.

They maintain high standards while moving at startup speed and they build real relationships with teammates because they know thats how great work gets done. When things get tough they adapt and keep pushing forward.

The people who thrive here treat AI like a natural extension of themselves. Theyve built their own ecosystem of agents - some for research others for debugging writing analysis or writing code. They know which AI works best for what problem.

Everyone gets premium accounts (ChatGPT Claude Perplexity Pro Cursor Lovable) plus a quarterly budget for new tools. But the magic happens in how we share knowledge. Demo days where someone shows off a clever workflows. Slack threads about which model handles a specific use case better. Learning from each others AI workflows.

At Siena were not just looking for people who can do a job. Were looking for people who want to break boundaries create the future and reshape industries. If thats you we look forward to your application.
