About the Role

You'll work directly with the CTO, founders, and legal engineers to build software around how litigators develop a case. You’ll own features across the stack, from the interface a lawyer uses to the data model and AI workflows behind it. This is a hands-on individual contributor role where you’ll write production code, make architectural decisions, and stay responsible for how your work performs after it ships.

Responsibilities

  • Own major features from the first design through launch and ongoing use.
  • Design data models that connect claims to the facts and evidence needed to prove them.
  • Preserve sources and allow lawyers to record competing interpretations.
  • Build workflows that extract people, events, and timelines from documents and help lawyers find gaps in the evidence.
  • Build evaluations and review tools that catch AI errors and incorporate attorney corrections without exposing information from other cases.
  • Make tradeoffs around reliability, performance, and cost.
  • Review code and help other engineers work through technical decisions.

Requirements

  • 5+ years shipping production software, including responsibility for designing, building, and maintaining a significant product or system.
  • Strong React, TypeScript, and Next.js skills.
  • Ability to build a usable interface and follow the work through the backend and database.
  • Experience building and operating LLM-powered features, including retrieval or agent workflows.
  • Experience making architectural decisions under constraints such as deadlines, cost, or performance.
  • Ability to work through unfamiliar problems with lawyers, explain technical choices, and give useful feedback to other engineers.
  • Curiosity about the domain and care for sensitive information are essential.
  • Must be authorized to work in the United States.
  • Not currently able to sponsor visas.
