Senior Mobile Engineer

ABOUT SIRO

Siro is a Series A company using AI to coach field sales professionals, i.e., anyone who conducts sales in person. Most sales professionals in the U.S. work in field sales, but get ZERO on-the-job coaching because they are alone in the field. Top-performing sales reps out-earn surgeons, but most do not.

Think of the person selling HVAC services, pest control, or solar panels. With Siro, these sales reps are empowered with data-driven coaching, actionable insights, and peer-to-peer learnings — enabling them to excel.

We believe that with the right tooling, field sales can become the most accessible path to financial freedom.
