AI in this role
Generalist role at an AI lab pushing frontier model intelligence and rebuilding the LLM stack from first principles.
We’re building prod, not god. TypeSafe is an AI lab pushing frontier model intelligence in a new direction, starting with System One Models. We combine the reasoning of LLMs with the reliability of code, for truly trustworthy AI. Our first model, Jev, launched in September 2026.
While others chase leaderboards, we’re rebuilding the LLM stack from first principles to make models smarter and also dependable enough to run in production. We’re a small, fast team backed by an $870M Series A led by a16z. Made in SF, with love. Come join the frontier.
About the RoleWhat 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
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.
