Founding Engineer at FluxCap

You would be one of the first engineering hires, working directly with the CTO and founders. Full-stack IC work: React/Next.js frontend, Typescript backend, Postgres with pgvector for the semantic layer. You'll sit with lawyers who ran the DOJ's biggest antitrust cases and translate how they reason into systems that can do it at scale. Legal reasoning isn't a search problem. A single document might strengthen one claim, undermine another, and be irrelevant to a third depending on which legal theory you're pursuing. Design the data layer that connects claims to elements to facts to evidence, structured enough for agents to reason over without hallucinating citations or skipping steps Build entity extraction workflows that pull structured claims, actors, and timelines from legal files Create agent workflows that surface gaps in legal arguments before a complaint gets filed Build evaluation frameworks where attorney corrections flow back into the system and sharpen future retrieval across every case
