Hey there 👋
We're Koko, a mental health nonprofit created by a team out of MIT and Airbnb. We’re backed by YCombinator and Fast Forward, and we’ve built services for most large Internet platforms, including TikTok, Pinterest, and Tumblr.
We’re building scalable AI systems that save lives. We provide online mental health support at the moment young people need it most. We reach young people where they are — online — and embed our interventions into the platforms they use every day (e.g., TikTok, Discord). So far, we've provided support to more than 4 million young people, reaching individuals across 199 countries and six continents.
We're looking for a technical leader with deep insight into AI's capabilities while maintaining a strong grasp of the ethical, safety, and privacy implications — particularly in sensitive domains like youth mental health. This is a full-time, remote role.

- Strong foundation in data science and machine learning, with experience using data to drive product decisions, design and analyze A/B tests, and measure impact.
- Deep understanding of modern AI capabilities and limitations, balanced with pragmatic product sense - you know when AI adds genuine value versus when simpler solutions would better serve users.
- Experience navigating complex ethical considerations in technology, particularly around safety, privacy, and responsible AI deployment.
- Demonstrated ability to move quickly and innovate while maintaining rigorous standards for safety and efficacy, especially when serving vulnerable populations
- Technical depth to evaluate and implement AI solutions when appropriate, while maintaining focus on core user needs and scalable impact.
Key Responsibilities
- Build and evolve our platform architecture, creating interfaces and systems that effectively combine AI capabilities with intuitive user experiences.
- Design and implement robust experimentation frameworks to continuously measure and improve the effectiveness of our services.
- Drive product decisions through data analysis, translating insights into features that measurably improve mental health outcomes.
- Ship and iterate on production features across our platform ecosystem (TikTok, Discord, etc.), directly impacting millions of young people.
- Advance the field of AI and digital mental health by contributing to peer-reviewed research and open-source initiatives, sharing insights that can help the broader community.
Compensation & Benefits
- Salary Range: $160,000 - $220,000 annually, based on experience and qualifications

- Flexible hours, fully remote, international offsites, no-meeting Fridays.
