## About the role

Apten is an omni-channel AI agent that automates sales and marketing conversations with millions of leads across SMS, voice, and email. Apten communicates exactly like a human — dynamically switching between channels, personalizing every follow-up, and proactively using tools (CRMs, schedulers, lead systems) in-conversation.

## What they're looking for

- Experience building and shipping production software (or equivalent skill) - personal projects are OK

- Strong product sense — able to make pragmatic tradeoffs, prioritize for impact, and ship fast
- Comfortable working across the stack (frontend → backend → infra)
- Previous startup or early-stage experience a plus
