Job description

TypeSafe AI is an AI lab building machine-native intelligence infrastructure for automation, designed to make decisions within software by combining the intelligence of LLMs with the efficiency and reliability of code into a new shape of AI: System One Models. Based in San Francisco, TypeSafe AI recently launched its first public model, Jev.

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

What role?! Maybe we haven't scoped it yet, but you've learned enough about the mission to believe we need you here. If you're an entrepreneurial builder of any kind — sales hustler, marketing demon, designer-of-worlds, something we can't even brainstorm in this list —don't let our lack of imagination stop you from introducing yourself.

Across Any Discipline, We Are Looking For People Who

• Are spiky in at least one domain and skillset, well-rounded in essential others, and have the self-awareness to know the difference
• Show complete ownership — can think about goals on a strategic level and define what needs to happen toward that goal, rather than at the level of tasks or tickets
• Solve problems from both first-principles reasoning and a reservoir of lived experience
• Understand and follow the AI industry and understand both the joys and the limitations of current-generation LLM models
• Care deeply about our mission and are driven to translate it into real-world impact
• Have 5+ years of professional expertise (to be clear: many of us are 10+ YOE) in high-performing teams, including under shifting and ambiguous environments

Life at TypeSafe

We’re a small, flat, close-knit team dedicated to real-world impact preparing the world for Transformative AI. Our team works fully in-person in our San Francisco office near Embarcadero station. We love what we do and care about our work a lot.

We strive for excellence and craftsmanship and won't stop until we get there. When the team wins, we all win, and we enjoy collaborating and inspiring each other to grow as a team and as individuals.

We also value emotional honesty, kindness, and bringing your whole self to work. We build machines; we don't try to be machines.

We want you to be able to do the most impactful work of your career at TypeSafe and help define our future as a company.

We provide

• Base salary of $150k–250k plus equity, based on leveling
• 100% covered health insurance
• Daily lunch and dinner
• Visa sponsorships
• 401K plans
