Reporting to the Development Manager, this role focuses on delivering reliable, secure, and scalable AI‑enabled pipelines and services that process caselaw across many jurisdictions, at a scale of millions of documents and tens of millions of citation relationships. You will work closely with partners across editorial and legal data teams, Data Engineering, and Platform Engineering to turn real problems in legal information into production‑grade solutions. This role owns the full lifecycle of what you build, from design and implementation through monitoring, iteration, and long‑term support. Design, build, and operate backend services and data pipelines that extract, classify, and resolve information from semi‑structured legal documents at scale.

Work with large, heterogeneous document sets and curated evaluation sets to measure model quality and drive it up over time. Ensure solutions are observable, reliable, secure, and cost‑efficient, with clear monitoring and operational ownership (e.g. Operate in the cloud (AWS: Batch,



Lambda, ECS, RDS/Postgres, S3, and search/vector stores such as Vespa) with solid CI/CD practices. Contribute to and uphold responsible AI standards, including privacy, security, legal accuracy, and audibility, given the sensitivity of legal data. Collaborate with cross‑functional and non‑technical partners (including legal editors) to translate ambiguous problems into transparent technical designs and shipped solutions.
