Closure helps law enforcement search evidence and solve crime. Police and prosecutors across the US use it to accelerate investigations into homicides, cold cases and other major offenses by reducing digital evidence overload, with about 10 live agency deployments and paying customers.
Closure was founded in 2025 by ex-Palantir and ex-IDF engineers who have built national-scale systems, and is backed by Y Combinator (W25), CRV, Hawktail, Liquid2 and Adverb.
As an early engineer you will shape Closure's AI backbone, processing massive video, audio and text datasets to surface investigative leads. The work spans backend infrastructure and applied ML: building retrieval pipelines, integrating LLMs and VLMs, and deploying secure, distributed systems in sensitive environments, end to end from data-flow design to production.
Free lunches and dinners, 3% 401(k) contribution, unlimited PTO, full health and dental, gym reimbursement, and FBI/CJIS clearance sponsorship.
