Job description

We are looking for top tier engineers to support us in building AI products. You will lead the development of algorithms that push the limirs of what is possible with LLMs.

What You’ll Own

• Production-Ready AI: Develop and deploy proprietary algorithms that significantly increase the quality of generated patents.
• SOTA Evaluation Pipelines: Build a robust, high-scale evaluation framework to benchmark our proprietary models and steer the direction of our R&D.
• Advanced Prompt Engineering: Research and implement cutting-edge prompting methods to maximize model efficacy.
• Full-Stack Impact: While focused on AI, you’ll work across the stack (Python, Postgres, React) to ensure our research translates into a seamless user experience.

We are the fastest-growing startup transforming the legal landscape. Our AI platform manages everything from invention harvesting to patent generation.

• Growth: 20-30% MoM revenue growth; selling to 300+ global IP teams (DLA Piper, tech giants, and boutiques).
• Backing: Recently featured in Sifted following our $40M Series B announcement, bringing our total funding to $55M from elite investors including Y Combinator, 20VC, Visionaries and others.

Must-Haves

• Expert Python Skills: Deep experience building and shipping AI solutions.
• Production Experience: A history of shipping algorithms and/or evaluation pipelines into live environments.
• LLM Mastery: Practical experience with prompt engineering and modern LLM architectures.
• Technical Versatility: Familiarity with the full stack (Postgres, TypeScript, React).
• Clear Communication: Ability to articulate complex technical decisions clearly.
