TypeSafe AI (https://typesafe.ai/) is a well-funded stealth mode company making a new class of AI models which enable a reliable way to embed composable intelligence into traditional software, founded by a co-author of ChatGPT/RLHF/GPT4 (answering the questions "If AI is so smart, why are we barely automating any work? Why does today's AI always need a human-in-the-loop?").
We're especially looking for people to join our Synthetic Data research team - no previous data experience needed (synthetic or otherwise). We need strong engineers who care deeply about the end use cases and whose instincts are to NOT trust LLMs blindly and look at the reality of their generations (much more investigator in the spectrum of investigator vs optimizer).
