TypeSafe AI
Develops system-one AI for software automation
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 a $870M Series A led by a16z. Made in SF, with love. Come join the frontier.
We want TypeSafe to be everywhere developers are: on stage at conferences, in the room at hackathons, on podcasts, and in the feeds engineers actually read. As a Developer Advocate, you'll be the public face of TypeSafe. Your job is to earn attention, teach large audiences what's possible, and make it obvious that TypeSafe is built for builders. This role sits closer to community and marketing than to engineering, but you will build. Every talk you give should come with a demo you made yourself.
Represent TypeSafe through conference talks, workshops, podcasts, livestreams, and hackathons
Build demos that show developers what TypeSafe can do and make them want to try it
Help define TypeSafe's voice with the developer community and reinforce our positioning as the platform for builders
Engage with developers on Discord, social channels, and at in-person events
Plan and run developer marketing moments: webinars, meetups, hackathons, and workshops
Bring what you hear from developers back to product, engineering, and marketing
Collaborate with product, marketing, engineering, operations, and leadership
A strong public presenter. People want to listen to you. You hold a room, whether it's 20 people at a meetup or 2,000 at a keynote.
You can teach a mixed audience. You explain hard ideas simply for newcomers without losing the experts in the room, and you can go deep when the advanced folks push.
You handle hard questions well. You can speak candidly about limitations and criticism in front of an audience, stay calm, and come out with more trust than you went in with.
You build compelling demos, and you know what makes one compelling. You can tell the difference between a demo that lands and one that doesn't.
You build independently. You can ship working demos on your own. Using AI coding tools is encouraged, but you understand what you've built well enough to explain it and answer questions about it live.
You love building with new technology. You stay current on what's new in AI and are excited to try it. Original or contrarian opinions you can defend are a plus.
You believe in what we're building. You're enthusiastic about TypeSafe and our mission, and it shows.

Develops system-one AI for software automation
TypeSafe AI builds machine-native automation inside software. Its flagship model, Jev, takes unstructured program state and returns typed, probabilistic decisions that software can act on, accessed via API in early access for workflows like routing, scoring, extraction, and verification. It uses a custom parallel sampler architecture and RL for Calibrated Decisions (RLCD) to control when and how decisions are made within applications. The company aims to embed programmable, reliable decision-making inside existing software to automate workflows, differentiating itself from consumer-focused chat AI and other AI vendors; it emerged from stealth in 2026 with a $40 million seed led by DCVC.
