About Citizen
Citizen’s mission is to protect the world by building a global safety network of people protecting each other via our free iOS/Android app. The network is powered by technology that generates instant alerts about public safety emergencies—as they occur. Each incident on the platform creates a temporary local network of people who use the Citizen product to protect each other, broadcasting live video and communicating with others nearby.
We’re looking for passionate, mission-driven individuals to help take the Citizen app to the next level as we scale up new cities and expand globally.
Citizen is backed by Sequoia Capital, 8VC, and Founder’s Fund.
Our Challenges
- Scaling: We have one of the fastest growing organic user bases in NYC, and right now we’re geo-restricted to New York City and San Francisco. Soon we will launch nationwide and we need to support that scale. A Citizen international launch will follow.
- Mobile video streaming: Our app will ingest high-quality video at low-latency, transcode, and redistribute the video to external media outlets seamlessly.
- Extracting signal from noise: During major breaking news events, tensions are high and a lack of information persists. We build tools to raise facts and suppress noise.
Our Stack - languages and technologies we use and teach
- Mobile: Swift (iOS), Kotlin/Java(Android)
- Web: React.js
- Server: Go, Node (for isolated systems)
- Systems: MySQL, Redis, Kafka, BigQuery (for isolated systems)
- Infrastructure: Kubernetes on GCP
