We are seeking a creative bilingual backend engineer to join the team behind CoCounsel. You will help build applications that interact with state-of-the-art Large Language Models (LLMs) that deliver cutting-edge and time-saving solutions to attorneys in Europe. CoCounsel is already capable of writing legal research memos, summarizing and reviewing documents, and red-lining contracts, just to name a few capabilities-all in minutes, not days or weeks. And we’re just getting started.
As a Software Engineer, Legal Prompter, you will develop Python code as well as German prose prompts to LLMs to help expand CoCounsel’s early success and localize CoCounsel to the European legal market. This mix of writing instructions for an interpreter and an LLM is well-suited for someone who can produce reliable backend code, and can also write creative, lucid, and effective prose instructions.
Our ideal candidate is a bilingual software engineer who can write high-quality Python, work with APIs (consuming and serving), and also has domain knowledge of the law (JD, legal industry experience such as courtroom interpreter or paralegal, etc.). A legal background is absolutely necessary. Candidate must be highly proficient in spoken and written German.

• Orchestrate LLM-driven experiences that delight our customers
• Develop Python code that interacts with state-of-the-art LLMs
• Write, test, and iterate German prose prompts for the LLM that leverage your legal domain knowledge, ensuring delivery of accurate, legally sound, and contextually appropriate responses
• Develop Python code that interacts with data sources & services (APIs, SQL databases, etc.)
• Liaise with legal professionals and other teams at Thomson Reuters to gather and understand requirements
• Integrate the language models into multi-step systems, assessing their performance and making necessary modifications
