The Role

We're hiring our next Customer Success Manager to own a book of high-value accounts, drive revenue retention and expansion, and help shape the CS infrastructure that will scale us to 100+ customers.

You'll own the full customer lifecycle from strategic onboarding through expansion and renewal, acting as a trusted advisor to your accounts.

• Technical aptitude - Comfortable with technical products, integrations, and complex configurations (not intimidated by data integrations, AI tools, or CRM workflows)
• Executive communication - Confident engaging with VPs and C-suite, both written and verbally
• Self-sufficient operator - Figures things out independently, creates processes where none exist, strong judgment and decision-making ability, thrives without constant direction

The Human We're Looking For:

You're energized by customers. Customer calls - even challenging ones - give you energy. You genuinely care about their success and take pride in being a trusted advisor.

You thrive on revenue impact. You're motivated by expansion wins, successful renewals, and seeing your accounts grow. You think in terms of ARR, retention %, and customer lifetime value.

You're a builder, not just an executor. You want to shape processes, create playbooks, and leave your fingerprints on how the CS function operates. You see gaps and suggest ideas to fill them.

You balance strategy and execution. You can have executive-level conversations about business outcomes AND dive into the technical weeds of CRM integrations. You're "full stack" in the best way.

You're resourceful and deadline-driven. You find creative solutions with limited resources, prioritize ruthlessly when everything feels urgent, and deliver results even when the path isn't perfectly clear.

You want meaningful ownership. You want to own outcomes, not just tasks. You want your work to directly impact company revenue and customer success, and you want to see that impact clearly.
