About the company

A Seed-stage AI company solving a real gap created by the AI coding boom. Tools like Claude Code and Cursor have engineers writing code faster than ever, but test coverage hasn't kept pace. Writing and maintaining end-to-end tests is still slow, manual work, and most teams either ship with thinner coverage than they'd like or slow down to catch up.

Their AI agents generate, run, and heal end-to-end tests automatically, delivered as Playwright code that lives in the customer's own repo. Teams get meaningful coverage in days instead of months, without adding QA headcount.

They've 10x'd ARR in the last 12 months and are on the verge of a Series A.

About the job

They're hiring their first dedicated Customer Success Manager to own onboarding, adoption, renewals, and expansion across their engineering-led book of business. You'll partner closely with their Customer Engineering team on implementation, run QBRs and exec-level relationships, and be the voice of the customer back to Product and Engineering.
