Job description
You'll be one of the first hires outside the founding team and your decisions will shape the product for years. You'll build across the full stack: multi-agent reasoning pipelines, retrieval over hundreds of millions of patents and scientific literature, and the surfaces that practitioners at top IP firms and Fortune 500 IP teams use daily. These are problems without established patterns. You're building agentic software that patent lawyers actually trust to do substantive work - and you'll define what this category of product looks like. ### **What you will do** * Build and improve the multi-agent architecture powering invalidity search, infringement analysis, freedom to operate research, and more * Own the full lifecycle of features - from talking to customers about what they need to watching them use it in production * Push code to production daily. Your code reaches users in hours or days, not weeks * Build retrieval, reasoning, and evaluation systems that run autonomously over millions of documents with reliable source-backed results * Set engineering standards for a codebase that will scale to a large team\\ ### **What we are looking for** * Exceptional matters more than experienced - we care about what you can do, not how long you've been doing it * Strong engineering fundamentals and opinionated about product * You write software with and for AI agents, and have shipped agentic systems before * You can take a product idea from sketch to production single-handedly - write the specs, build the UI, wire the agent pipeline, deploy the infra * Comfortable across Python and TypeScript, and you've worked with enough infrastructure - vector databases, distributed compute, cloud orchestration - that none of it slows you down * Experience navigating enterprise requirements - SOC 2, data residency, access controls - is a plus
