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 ROLE

You take the hardest problems our customers hit in production and solve them end to end. A webhook that stopped firing overnight. An agent filling the wrong parameter. A report that won't reconcile. Today those land on a product engineer's desk and pull them off the roadmap. That stops with you.

- More than troubleshooting. You find the real cause, work the customer directly to a resolution (including jumping on a call when that's fastest), then build the automation so it never comes back.

- You're an accelerator. Every fix makes the next one faster and the product better.

- A clear path forward. This is the front door to deployment and platform work at Siena. Grow from here into a Forward Deployed Engineer or deeper into platform engineering.
