About TypeSafe

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.

About the role

We want every developer to be able to learn TypeSafe on their own, quickly and correctly. As a Developer Educator, you'll build the learning resources that make that possible. This role sits closer to engineering and product than to marketing. You'll write code, write about code, and make judgment calls about how developers, and the AI agents they work with, learn best.

What you'll do

• Own the developer learning experience across docs, tutorials, cookbooks, and SDK/API references.

• Write documentation and examples that are specific, accurate, and honest about tradeoffs

• Design curricula and learning paths for developers at different levels

• Write case studies with first-hand perspective on how developers build with TypeSafe

• Structure our docs and learning resources so both developers and coding agents can use them

• Write clear specs and prioritize work with product and engineering

• Measure whether our learning resources work, and improve them based on the results

• Bring learner feedback back to product and engineering

What we're looking for

• Strong engineering judgment. You use AI coding tools well, and you know when generated code is wrong, fragile, or teaching bad habits.

• Skill in teaching, especially for code. You know how to sequence concepts, choose examples, and teach technical topics through code.

• You build accurate mental models of new APIs quickly, or you've gone deep on a niche API and can show it.

• Excellent technical writing. Your writing is specific, accurate, calibrated, rigorous, and transparent about what works and what doesn't. You have strong editorial judgment.

• Storytelling with first-hand perspective. You can turn real experience into a narrative that teaches.

• You understand where people get stuck, especially with AI products, and have experience that shows it.

• Information architecture that accounts for agents. You keep on top of the rapidly changing landscape of how agents access and process documentation.

• Curriculum and instructional design experience.

• You understand what developers are trying to accomplish and how our product fits.

• Clear communication and prioritization. You can write a clear spec and decide what matters most.

• You take responsibility for outcomes and measure your own effectiveness.

• More than 3 years of experience as a software engineer, developer advocate, or technical writer working with code

• Published technical writing, tutorials, or courses you can share
