Backend Engineer (Infrastructure) en Lassie

Lassie

Doctors learn medicine — not business — and shouldn’t have to be experts at both. Most aspire to be independent, but as their practices get buried in paperwork and broken systems, they’re forced to give up. We put independent doctors’ businesses on autopilot so they can focus on care.

Our founding team scaled growth at Robinhood and Coinbase, early product at Superhuman, and built systems at Pinterest, Netflix, and early Zenefits. We’re backed by investors like Homebrew, SV Angel, Unusual, and Sequoia scouts, along with founders of Commure, TransferWise, and Superhuman, and early employees from Stripe, Ramp, Plaid, Robinhood, Coinbase, and more.
