Engineering Manager, Channels & Platform

Job description

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.

This isn't a coordinator role. You run 1:1s, keep cycle cadence honest, write technical debt plans alongside engineers, unblock people before it becomes an escalation, and act as a genuine thought partner on the operational side. Scope changes and anything that reshapes the team are joint calls. Everything else is yours. What you'll do Delivery (≈50% of your time): Own the weekly cadence for Channels and Analytics.
