ABOUT TYPESAFE 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 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. WHAT YOU'LL OWN - Narrative and content: shape the company blog, thought pieces, and our unique perspective on AI, and position our founders and researchers as leading voices - Product marketing: define our category and translate deeply technical capabilities into messaging that developers resonate with - Brand and channels: own our company brand, website, and social cadence across X and LinkedIn - Launches and announcements: coordinate product releases and announcements from press to podcasts to events - Demand generation: build developer and enterprise interest to build our pipeline WE ARE LOOKING FOR PEOPLE WHO - Have built a marketing function from zero at a start-up and can both set strategy and execute it - Are tactically broad — can own narrative, launches, demand, and growth experiments across channels from social to SEO to email - Have 5+ years of professional expertise in high-performing teams, including under shifting and ambiguous environments - Write exceptionally well — clear, technical, and fast - Have taste: know what's credible, what's hype, and what's premature - Are fluent in the AI industry, leverage tools yourself, and can credibly talk models and APIs with our engineers and researchers - Show complete ownership — think at the level of goals, not tasks or tickets - 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 LIFE AT TYPESAFE We’re a small, flat, close-knit team working to make intelligence dependable enough to become part of everyday software. We work fully in person from our San Francisco office near Embarcadero station. We love what we do and care deeply about the work. 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 value emotional honesty, kindness, and bringing your whole self to work. We build machines; we don’t try to be machines. We want TypeSafe to be the place where you do the most impactful work of your career and help define our future as a company.
