## Job description

### 🎤 Why voize? Because we’re more than just a job!

At voize, **we believe the greatest gift to frontline workers is time - time to care, connect, and be present.** Today, that time is lost to admin work that pulls nurses away from what matters most: **people**.

We’re changing that by building the AI companion that frees nurses from admin, **giving them back up to 30% of time**. We don’t replace humans - we support and amplify their impact. **Today, 2,000+ care facilities trust voize, and over 200,000 nurses rely on our AI companion** to ease their daily workload.

Our mission is backed with a **$50M Series A funding led by Balderton Capital, with support from HV Capital, Y Combinator and other leading VCs.**

As a fast-growing team, we combine first-in-class technology with meaningful social impact. **And now, we’re looking for you to join us on this mission!**
