Role summary
Closure is seeking a founding backend engineer with deep experience and interest in applying AI in real-world settings, particularly within the criminal justice system. The role involves building resilient, secure distributed systems, deploying LLMs, VLMs, and ML models, and designing data pipelines (RAG, structured data). Candidates should be comfortable with Python and cloud infrastructure, and ideally have experience with agentic AI. This is a demanding, fast-paced role requiring proactivity, hard work, and adaptability, with a preferred location in New York City or a hybrid arrangement in the Bay Area.
**About Closure**
Closure helps law enforcement search evidence and solve crime.
Public servants across the U.S. use Closure to expedite investigations into cold cases, homicides, gang conflicts, sexual assault, and other serious offenses. We’re live with police departments and prosecutors across the country, reducing evidence overload throughout the criminal justice system.
Closure is an **intentionally tight-knit team** of ambitious ex-Palantir and ex-IDF engineers and operators. We operate with a high speed, high integrity, and high autonomy, backed by reputable investors including **Y Combinator, CRV, Pathlight,** and others.
