Developer Advocate

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.

What you'll do

• 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

What we're looking for

• 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.

• Have >3 yrs experience as a SWE or developer advocate

• An established following or reputation in the developer community

• Experience producing audio, video, or other content

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.
