- Secure our first commercial wins and design partners.

Requirements:

- Technical Fluency: You understand browser automation mechanics and the current LLM landscape.

- 5+ years experience: A mix of DevRel, Technical Sales, PMM, or Founder experience.

- Founder Hustle: You can generate leads and write technical docs without a massive marketing budget.

Values: You align with Mozilla’s mission of a healthy, open internet.
