TypeSafe AI•San Francisco, CA

About The Position

TypeSafe is a frontier model lab. We build reliable and general AI systems to power economically valuable automation. Our mission is to usher in a new era of Transformative Artificial Intelligence (TAI): technology with the power to drive a societal shift on the scale of the agricultural and industrial revolutions. While others chase benchmarks and academic puzzles, we've been quietly rethinking the LLM stack from first principles — building a new kind of general frontier model designed for real-world reliability, decision-making, and autonomy in production. We're a small, fast-moving team from OpenAI, Google Brain, and Meta/FAIR, backed by top-tier investors. Since mid-2024, we've been engineering the foundation for what comes after the current "state-of-the-art" — a model that actually gets things done. About the role: You'll own how TypeSafe shows up in the world, from the story we tell to how developers and enterprises discover, adopt, and champion what we build. There's no team to inherit and no playbook to run. You'll work at all altitudes — setting the high-level strategy and then doing the tactical work yourself, from positioning down to the copy.

Solve problems from both first-principles reasoning and a reservoir of lived experience
Care deeply about our mission and are driven to translate it into real-world impact
