Founding Engineer
Waldium
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 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. #J-18808-Ljbffr Waldium
