We’re a team of ex-CTOs, founders, and builders who thrive on solving hard problems with high velocity. Egos are checked at the door—what matters is shipping transformative technology.
We’ve built a prompt-first programming language that combines the simplicity of Notion with the structured power of code and LLMs. Our vision? To create the AI-native operating system that will redefine how software is built for the next decade.
Backed by the largest seed round in YC history ($30M), we’re scaling fast with 300,000+ signups and a product at the forefront of the AI revolution. Now, we need exceptional engineers to help us execute on this ambitious mission.
Design and build the core architecture of our AI-driven programming language and runtime.
Work at the intersection of LLMs, developer tools, and human-computer interaction—blurring the lines between natural language and code.
Optimize for abstraction, usability, and performance in a system that empowers both technical and non-technical users.
Collaborate with a small, elite team to ship fast and iterate relentlessly.
Shape the future of AI-native development alongside founders and early engineers.
A pragmatic systems thinker with deep experience in programming languages, compilers, or developer tools (or a voracious appetite to learn).
Passionate about AI/ML and how LLMs can revolutionize software creation.
Comfortable in low-level systems (e.g., Rust, Go, C++) and high-level UX (e.g., TypeScript, React).
Obsessed with clean abstractions and removing friction for users.
Thrive in 0→1 environments—you ship fast, debate fiercely, and execute relentlessly.
Bonus: Experience with language design, DSLs, or AI-powered tooling.
Work on a category-defining product with massive traction.
Learn from ex-CTOs and founders who’ve built and scaled before.
Competitive salary, equity, and benefits (top-tier health, 401k, etc.).
Hybrid flexibility in one of SF’s most inspiring offices (Crissy Field views included).
If you’re ready to build the future of AI-powered development, we want to hear from you. No fancy cover letters—just share what you’ve built and why you’re excited to reinvent how software gets made.
