Founding Customer Success Manager

We are looking for a Founding Customer Success Manager with 3-5 years of experience to own the post-sale customer relationship and drive usage expansion at Hyperscale. You'll manage a growing roster of customers, run regular meetings, identify new use cases, and work with deployed engineers to expand what our AI agent handles for each account. This is a founding role — there's no CS team or playbook yet, and you'll build both from scratch working directly with the founders. Comp is structured 80/20 with variable tied to usage expansion across your book of business.

What will you be doing?

- Own the customer relationship post-sale: run regular meeting cadences, drive adoption, and expand usage across accounts

- Onboard new customers end-to-end — from kickoff workshops to daily product usage

- Identify new use cases within existing accounts and coordinate with deployed engineers to implement them

- Field inbound support requests, resolve what you can, and route the rest to engineering with proper context

- Build the customer success playbook and processes from scratch, using AI to automate repetitive workflows as the customer base grows
