Staff Parser/Compiler Research Engineer

Job description

[.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** .txt is a fully remote company with the majority of the team in the US and EU. For this role, you must be based in the US. ## **Applying** Please provide a 1-page resume in English. Only apply to one position at a time.
