Customer Success Manager

Siena AI

17h • Remote

About The Position

Siena is the first intelligence layer for customer experience. We're creating an operating system of AI agents that learn, remember, and act across every customer touchpoint—from support conversations to shopping experiences to voice and social media interactions.
Siena doesn't just automate support; it powers shopping agents, builds persistent customer memory, generates actionable business insights, and creates empathetic interactions that feel human.
We're transforming how businesses understand and connect with their customers, turning every interaction into intelligence that makes the next one better.
We're a small, distributed team that punches way above our weight. Every person here has outsized impact because we've built leverage into everything we do. This philosophy makes us faster and, frankly, more fun to work with.
If you're excited about building something that doesn't exist yet, keep reading. We're building agents that don't just respond to customers—they remember them, learn from every interaction, and connect experiences across channels.
This is not a relationship-only CSM role. As a CSM at Siena, you own a portfolio of customers and hold them to specific, measurable outcomes. You are accountable for how well Siena performs and how much value customers actually realize.
You will operate at the intersection of customer, product, sales, and engineering. You’ll lead audits, improvement plans, and cross-functional execution to move real metrics, not just run QBRs.
