Customer Success Manager
About the role
THE ROLE
Coval has a strong land-and-expand motion. You'll own the customer relationship post-sale: onboarding, adoption, retention, and expansion. Your job is to turn every landed account into a growing one.
• Drive onboarding and adoption. Get customers live, help them build evaluation strategies that actually surface signal, and make sure the right people inside their org are using the platform.
• Own expansion. Navigate internal orgs to find the buyer, connect the buyer with the user, and build the business case for expanding budgets. You're the account executive for growth within existing accounts.
• Coordinate with Forward Deployed Engineering. You'll work closely with our FDE team to make sure technical implementation matches what the customer needs. You set the direction; they build the solution.
• Be the voice of the customer internally. You'll know what's working, what's not, and what customers need next — and you'll make sure the product team hears it.
WHAT WE'RE LOOKING FOR
• You've done customer success, account management, or post-sale work at a technical product company, ideally a fast-moving startup.
• You can navigate complex organizations: find the decision-maker, build the champion, make the business case.
• You're comfortable with technical products. You don't need to write code, but you need to understand what evaluation infrastructure means for a voice AI team and speak their language.
• You're organized and proactive. You don't wait for customers to tell you something is wrong.
• You're genuinely curious about voice AI and want to develop real expertise in evaluation infrastructure.
About Coval
What Coval Does
Coval is the simulation and evaluation platform for voice AI. We help companies answer the question most can't: do their voice agents actually work? Not in a demo. At scale, in production, with real users.
Most teams building voice agents are flying blind. They ship a demo that works, deploy it, and discover weeks later that 40% of conversations are failing. No evaluation infrastructure. No way to catch regressions before users do.
We built Coval because we've seen this movie before. Brooke led evaluation infrastructure at Waymo, where it takes millions of simulated miles before a vehicle touches a public road. Voice agents need the same rigor. Right now, almost nobody has it.
Nine people, backed by YC, closing six-figure enterprise deals with Fortune 500 companies, growing revenue 10x year over year. The space is moving fast. We're at the center of it.
What It's Like Here
We work in-person in SoMa, San Francisco. The office is shoes-off, full of plants, and dog-friendly. We bike, hike, skate, and run half-marathons together.
The team comes from Waymo, Zoox, Apple, and Google. We're hard on our work but never hard on each other. We ship on Sundays because we want to, not because someone told us to. We move at AI speed: what used to take weeks happens in hours.
Our operating principle is "wholesome and unhinged." We are relentless about making things happen, but we don't take ourselves too seriously. If you thrive in ambiguity, move fast, and want to be one of the first people building the sales foundations at a company that's already closing Fortune 500 deals, this is it.
Voice AI is where the market is going. We're already there. This is the best time to join.
