[planlab.ai](http://planlab.ai) is a VC-backed startup building automated planning for infrastructure construction projects. Project overruns cost global economy over $580bn each year, because planning is broken: tech invented in 1950s cannot manage modern complexity. We are creating a tool that overhauls the way planning is done by creating structural models of how projects work, rather than capturing what humans think the plan should be.

We're building Aide, an AI-native, privacy-first IDE. With the advent of AI, we believe there is an opportunity and necessity to re-imagine the IDE to be a place where developers and AI are both first-class citizens, and AI can pair-program as well as complete tasks independently.
We're still a team of 2, and are looking for a founding engineer with hands-on experience working with LLMs beyond basic prompting.

So someone who can understand and get into the internals of LLMs, hosting models, optimising model inference for our use case, setup evals, and (this may not be a skill you already have) can power the backend for streaming requirements needed to build agents in the next few years.

At bloop (https://www.bloop.ai) we modernise legacy code, translating old languages to new(er) ones. Existing translators produce code that is unreadable, and the alternative of rewriting an old system from scratch in a new language is unfeasibly expensive for many projects. We're developing a new approach that uses LLMs to automatically generate readable, maintainable code.
We're working to modernise code for a cohort of enterprise customers. You'll join a small group of compiler and ML engineers who are obsessed with the technical challenges posed by code translation.
We love:
* LLM pipelines
* Static analysis (Tree-sitter)
* Rust
