Engineers that enjoy hard things (like compilers)

About Boundary

The programming language for AI

Tech

Our compiler and runtime are fully Open Source on our [Github](github.com/BoundaryML/baml/tree/canary/engine/baml-vm). Our observability stack has a Rust backend, with a React + TypeScript frontend, hosted on AWS.

The role

We are building [BAML](https://github.com/BoundaryML/baml) -- a new programming language to build AI powered applications.What does the code look like when 50% of the business decisions is decided by an AI agent / prompts? How do you test these AI components? What tools should we build?Every computing paradigm, brought with a new language* Desktop Computer → Holepunching and ASM were far too inaccessible → C* Multiple OSs → Why write 3 variants of C → Java* A computer on every desk → Lets make software more readable → Python* Web browsers → Event driven / async native → JS* AI / Graphics → We need to do a lot of math, and fast → Cuda* Interactive Website → HTML + Logic is hard to do at scale → React* **Non-determinism → My software is isn’t predictable because AI → ?????**BAML is our answer, and it will let more developers than ever write AI pipelines without having to think about AI model reliability.### Why you should join usMost startups die quietly. Most programming languages never leave a compiler talk.But every once in a generation, someone builds the next C, Java, Python, JS, React or Cuda.\We’re trying to build that: a language for reasoning with AI.We might fail spectacularly.\But if we don’t, it’ll be because a small group of curious, fearless builders decided to bet on **beauty and correctness** in an age of chaos.If that excites you, then Boundary is your place.\But don’t take our word for it, [try BAML first](https://github.com/boundaryml/baml).### Responsibilities* Since we’re building a compiler, you’ll be able to solve some of the hardest and most interesting problems — e.g. how to suspend/resume AI workflows, how to support calling BAML functions from any language, how to create a graph visualization from BAML code users or AI agents write, and exploring unique syntaxes.* Design and implement tooling to give users the best developer experience — this includes adding features to our LLM observability platform and scaling it to support handling billions of logs.* Answer community questions and learn how they leverage BAML so we can make it even better### To apply:The best words that describe the kinds of people we’ve hired to date are: Curious and Fearless* Curious - never assume you already know, and challenge the status quo* Fearless - build anything. Its just bits on a machine, make them do what you wantSend a message through Work-At-A-Startup with Subject: “**Why I’m awesome**” with **3** of your most incredible achievements in life (technical and/or personal achievements). E.g. “I ran an ultramarathon in XYZ hours” or “I wrote a Rust crate used by millions of devs each month”. Brag about yourself, and articulate what about it was hard and what outcome came from it. \\**This isn’t a trick question, we’re building a programming language, and communication is the most important trait for us.**> Past Examples from candidates we’ve hired. READ THESE so you know what we might look for. **The best emails include metrics + links.**>> https://drive.google.com/file/d/1pFXmqQVnMmCdxdpcuF9Zwk6SRCMgJglL/view?usp=drive_link### Our Tech StackBAML - Rust + FFI bindings to each language we interface withBAML LSP / Editor Extensions (VSCode, Jetbrains, Zed, …) - Typescript/Nextjs, Rust + WASMBoundary Cloud - Rust backend, Typescript / Nextjs frontend## FAQDo I need to know Rust? No, but you should be able to learn it, and learn it fast.Do I need to know about programming languages / compilers? No, we don’t need to hire language experts. We train language experts.Generally speaking, no prior knowledge needed, but you should be able to take any problem, and solve it. If graph / tree problems are stressful, Boundary is probably not a good fit. If questions like the following seem fun, this is gonna be a heck of ride.* what syntax ergonomics can make AI better at grepping for code?* how does LLVM work?* how does react’s re-rendering work?* how do I design a package manager?
