Founding AI Engineer

Discernis builds AI for legal discovery, helping legal teams analyze large collections of documents. The Founding AI Engineer will take ownership of the AI stack, including agentic workflows, retrieval and evaluation, inference optimization, fine-tuning, and post-training, and set the company’s AI direction.

Responsibilities:

• High-recall retrieval and synthesis across billion-token document collections
• Agents that are reliable, testable, and deployable, not just impressive in a demo
• Getting strong performance from small open-source models in air-gapped environments
• Evals that capture what "correct" means to a litigator
• RL that trades off tool use against compute
