About the job
.txt https://dottxt.ai builds structured generation: we make language models produce output that follows a given format, by deciding at every decoding step which tokens are allowed. We compile a JSON Schema, a regex, a grammar, a list of function definitions or a policy into that decision, fast enough to run inside the decoding loop. This is how .txt builds reliable and safe agents. We're looking for a developer to work on the parsers and compilers at the center of it.
RESPONSIBILITIES
- Design and Develop: Craft high-performance parsers and data structures that integrate with LLMs.
- Problem Solving: Research advanced parser and compiler technology and symbolic methods.
- Writing Quality Code: Ensure the reliability and efficiency of our methods through rigorous testing and optimization.
- Stay Ahead: Learn the latest, relevant LLM advancements.
QUALIFICATIONS
- You know Python at a professional level and have practical experience with "lower-level" languages (e.g. C/C++, Rust)
- You have worked directly with parsers (e.g. Earley, LALR(1)), formal grammars, finite-state machines, and implemented efficient data structures. You are also capable of doing research and development in those areas.
- You are familiar with our relevant technical report https://arxiv.org/abs/2307.09702 and open-source project https://github.com/outlines-dev/outlines.
- You value simplicity, testing, and automation, and you can demonstrate this.
- You communicate clearly, concisely, and consistently in written form.
WHY YOU SHOULD JOIN US:
🧭 The problem matters Every agent that takes real actions needs a layer that guarantees it can only do what it was asked. The parser and compiler work in this role is what enables this guarantee.
🌐 Remote first Work from anywhere in the world. We communicate mostly in writing and favor occasional organic discussions over recurring large team meetings.
💸 Competitive compensation and benefits Market-rate salary plus stock options, health and dental insurance, and a 401(k) for US employees. We'll also get you a GPU if you don't have one.
Location
