About this role

Role Overview

The Backend Engineer, Applied AI position at Citizen in New York City is a full-time office-based role focused on building and scaling real-time safety infrastructure using AI agents. This role suits an exceptional backend engineer who runs agents as a second pair of hands, treats system correctness with urgency, and wants to work closely with a small, high-output team in New York City every day.

Key Responsibilities

Own core pieces of the real-time system, including ingest, detection, verification, geolocation, and distribution to millions of devices in seconds.
Build and maintain live video infrastructure, manage the backend behind ProtectOS and Regulator internal operator tooling, and support enterprise services, public APIs, and partner integrations like Axon.
Extend and operate agent loops that draft, review, test, and operate backend code, proposing where agents can run autonomously behind audited policy gates.
Register Segment events with the data team, verify them in BigQuery, and ensure leadership dashboards reflect accurate system telemetry.
Participate in an on-call rotational program, handling urgent 24/7 emergencies roughly one week every two months.
Complete onboarding milestones within the first 90 days, ranging from shipping to production in week one and driving end-to-end initiatives to launching new AI-in-pipeline capabilities.

Requirements

Experience building and running backend systems at consumer scale, real-time, or event-driven, with personal ownership of specific services.
Fluency in Go and comfort with Python for machine learning and data pipelines.
Experience working with Kubernetes and modern cloud stacks, including message queues, relational and analytical stores, and observability.
Practical background carrying a pager for critical production systems.
Production experience putting ML models or LLMs into operational paths with evaluation, fallbacks, and audit capabilities.
Active habit of building with AI, using agents to replace parts of the workflow, and understanding their failure modes.
Strong instrumentation practices, measuring events before arguing and verifying data warehouse ingestion.
High agency, mission-driven mindset, and ability to work full-time from the New York City office every day.
