Member of Technical Staff, Forward Deployed
Voice AI that resolves, not transfers.
Most phone systems trap callers in menus and scripts. Vapi is the platform for deploying voice agents that know your business and can listen, adapt, and resolve in minutes.
The numbers: 1 billion calls. 1 million developers. 10x enterprise ARR growth
The customers: Amazon Ring, ServiceTitan, New York Life, Intuit, Kavak, and thousands more, from YC startups to the Fortune 500
The news: a $50M Series B led by Peak XV Partners, with Bessemer Venture Partners, Kleiner Perkins, M12 (Microsoft's Venture Fund), Y Combinator, and our earlier backers. Total raised: $72M
Why We're Hiring This Role
Our Enterprise ARR is growing ~5x YoY — customers like NYLife and Intuit deploy in weeks and expand rapidly when we support them well. We're hiring an FDE to be the reason that flywheel spins faster. You won't just onboard customers; you'll identify the next use case, build the tooling that makes the next similar deployment trivial, and close the gap between what our product can do and what our customers actually need.
What You'll Do
30 Day: Deploy an Enterprise customer end-to-end
60 Day: Ship internal tooling or product contributions that make the next similar deployment materially faster
90 Day: Establish a process or infrastructure the team didn't know it needed
Who You Are
You've worked in a technical role at an early-stage startup — you know what it means to build without a playbook
You've been an FDE, Solutions Architect, or Solutions Engineer at a company we admire
You've driven process change proactively — not because someone asked, but because you couldn't leave a broken system alone
You're comfortable operating in ambiguity and find structure by doing, not by waiting
You have a genuine bias toward action: you identify a gap, you fix it, you document it
Bonus: You've built your own startup or pursued your own projects, and iterated on them
