About the Role

Join a founding-stage team building AI tools for public safety and criminal investigations. As a senior technical contributor, you will develop secure, production-grade systems that help investigative teams find and analyze evidence.

What You'll Do

• Build resilient, secure distributed systems for AI-driven evidence search and analysis.

• Deploy language models, vision models, and other machine learning systems in production.

• Design retrieval-augmented generation pipelines and semantic search infrastructure for unstructured data.

• Architect structured data systems, including query planning and semantic reasoning layers.

• Develop or work with agentic systems that reason, plan, and act across investigative data.

• Evaluate emerging models and infrastructure approaches, and own solutions from design through deployment.

What We're Looking For

• At least 6 years of backend engineering experience building distributed systems, including production deployment of LLMs, vision models, or other machine learning systems.

• Strong skills across multiple programming languages, including Python; experience with JavaScript and React is useful.

• Experience designing RAG or similar pipelines for unstructured data, and building structured data systems with query planning, semantic modeling, or reasoning.

• Experience working with multiple infrastructure providers and designing for security and resilience.

• Background spanning an established technology organization and an early-stage startup, with ownership in fast-moving, ambiguous environments.
