The Mission Make voice AI feel human.

The team brings deep linguistic and machine learning expertise to close the gap between how machines sound and how people actually speak — with warmth, authenticity, and emotional nuance built into every model.

The Opportunity As a Lead Developer Evangelist , you'll own how developers discover, evaluate, and adopt the product — online and in person.

You'll work directly with the Head of Marketing and have close access to the CEO and product team.

There's no content calendar waiting for you, no playbook to execute, and no team to manage before you've proven yourself.

What there is: a company at a high-growth inflection point, a developer audience that hasn't been properly reached yet, and full creative latitude to go build that.
