Role summary
Waldium is seeking a Founding Engineer to build authoritative indexes of the web and surface high-quality knowledge. This role involves developing AI-mediated research and writing tools, focusing on machine-readable content. Responsibilities include accelerating web crawlers, building web-scale search indexes, ensuring service uptime for their web-hosting platform (currently on Vercel), and improving their codebase indexer. The ideal candidate has experience building performant systems from scratch, is comfortable integrating production-ready AI systems across the stack, and has strong prompt engineering skills or the ability to ramp up quickly. This is an in-person role based in San Francisco.
### About Waldium
**Technical content today is written for humans.**\
We start from the premise that it should also be written for intelligent systems to learn from.
Waldium is a workspace for AI-mediated research and writing. You explore ideas with AI, synthesize source material, and publish technical work that intelligent systems can interpret, cite, and build upon. The result is knowledge that endures — structured, verifiable, and ready for both humans and machines to learn from.
We're a small, tight-knit in-person team based in San Francisco.
### About the role
Build authoritative indexes of the web and surfacing high quality knowledge are the pre-eminent problems as the web evolves from human-readable pages to machine-readable intelligence. We’re building Waldium to be a foundational part of solving them.
**Desired Experience**
* Built performant systems from ground up in 0 - 1 situations and owning the full software development lifecycle.
* Have extensive prompt engineering experience, or would be excited to ramp up very quickly
* Comfortable integrating production ready AI systems across the stack (i.e. running model inference, evals and benchmarks, agentic workflows).
* Care deeply about fixing the status of publishing technical content today - broken, stale, manual.
* Bonus points if you’re an ex-founder or founding engineer
**Responsibilities**
You will work with us to:
* Make our crawler 10x faster
* Build web-scale search indexes to surface results that are novel for both humans and AI
* Ensure that our web-hosting service (currently powered by Vercel) _never_ goes down
* Improve our codebase indexer to accurately, and correctly, surface topics from Github
Still apply even if you think you don't fit all the criteria—exceptionally good engineers often don't follow conventional paths.
