Job Description

SENIOR FOUNDING ENGINEER

Overview

We now handle millions of calls per month and need an engineer who has worked at that scale before and knows how to build systems that don't break under it. This is an architecture-heavy, full-stack role, not just backend. You will own everything from database optimization to reducing dashboard load times from four seconds to sub-100 milliseconds.

We're looking for someone in their late 20s who has moved fast inside engineering teams that move fast, brings solid practices into a growing codebase, and is the kind of person who has put hundreds of hours into mastering something outside of work. If you've never taken a hobby to an extreme, this is not the role for you.

You will work on-site at the SF office (moving to a larger space in three months), directly with the founding team.
