Job Description:
Lassie is building the AI for every health practice. One million
health practices spend $100B a year on admin staff, and still can't
find enough people. Since COVID, offices are chronically
short-staffed. Patients feel it every day in unanswered calls and
confusing bills. We believe the doctor's office of the future is
run by AI. An agent that runs the business, handles the
administration, and becomes the interface patients use to interact
with their doctor's office. Founded by Steijn Pelle (helped
Robinhood and Coinbase grow to their first hundreds of millions in
annual revenue) and Frédéric Renken (engineer turned first product
hire at Superhuman), we're bringing consumer product DNA to
healthcare and reimagining how a million doctors and 300 million
patients interact with the doctor's office. About the role We're
hiring a software engineer to own the systems that power the entire
customer journey: how practices find us, sign up, and go live.
Independent health practices are stretched thin and need better
tools. You'll help them discover Lassie and get successful fast.
Working closely with sales and product, you'll build infrastructure
that makes deals close smoothly and new customers successful from
day one. This role is ideal for someone who loves experimenting,
moves fast, and wants to see their work directly impact revenue.
You will be a great fit if you… Are excited about experimenting,
being wrong, and thinking from first principles Create tools and
systems that multiply the impact of sales and engineering
