About Citizen

Citizen is a free app that keeps you and your loved ones safe. It is a powerful force for good that has already evacuated people from burning buildings, diverted school buses from nearby terrorist attacks and reunited missing children with their parents.

Using our unique technology, 911 alerts are made available to the public and are accompanied by live stories, real-time updates, and user-generated content to provide you with the information you need to protect yourself and your loved ones. We act fast, break news, and give people the immediate information they need to stay safe. And we’re just getting started.

This year Citizen will expand further across the United States with the express mission of making your world a safer place. We’re looking for hardworking, mission-driven individuals to help take the Citizen app to the next level as we scale up nationwide. With a group of passionate builders from Facebook, Square, Uber, Google and HQ Trivia, Citizen is the company your current company doesn’t want you to know about.

Citizen is backed by Sequoia Capital, 8VC, Founders Fund, and Goodwater Capital and has raised tens of millions in VC funding. 


Our Challenges
  • Scaling: We have one of the fastest-growing organic user bases in NYC, and have expanded to multiple other cities. We are focused on the nationwide launch and the need to support that scale. A Citizen international launch will follow.
  • Bursting: We designed our infrastructure to scale without notice in case of a spontaneous incident where we need to inform our entire user base. On significant events, we see over a million simultaneously connected clients and their associated live streams. The core systems need to be able to efficiently support these traffic patterns and continue to scale to millions of more users in the future.
  • Machine learning: We process thousands of hours of audio every day looking for incidents that impact our users’ safety. To do this at scale, we’ve built ML models for audio analysis and targeting using the current state of the art from academia.
  • Analytics: We want to alert users to the incidents that matter to them, in a way that scales across different geographic densities and demographics.
  • Mobile video streaming: Our app will ingest high-quality video at low-latency, transcode, and redistribute the video to external media outlets seamlessly.
  • Radio hardware: We build our own software-defined radio-based devices to consume all radio dispatch in every major city, whether analog or digital.
Our Stack - languages and technologies we use and teach
    • Mobile: Swift (iOS), Kotlin (Android)
    • Web: React.js, TypeScript
    • Services: Go for transactional systems; Python for analytical systems
    • Datastores: Cassandra, MySQL, Redis, Google PubSub
    • Infrastructure: Kubernetes on Google Cloud
Role Description
    • While we launched on iOS first, we've found we have a significant, fast-growing base of Android users that in many neighborhoods has already surpassed iOS. The Senior Android Engineer will drive our mobile product execution for the Android platform in concert with the iOS engineers.
    • We view Android as a core offering, not as a follow-on to iOS. We want to be able to launch and experiment with new features in both.
    • Work with Product and Design to define and iterate on product scope and features.
    • Collaborate with iOS, Backend, and Data Science to build and launch new features, as well as re-architect and maintain existing features.
    • Collaborate across Engineering with designs, code reviews, and whiteboard sessions. We strive to eliminate errors and wasted cycles developing code.
    • Demonstrate rigor with code quality, best practices, and code review, while understanding product tradeoffs.
Preferred Qualifications
    • Bachelor’s Degree in Computer Science or related field
    • 5 years experience as a developer building applications for Android
    • Proficient in Java/Kotlin with strong object-oriented development
    • Stays current on Android platform developments
    • Champions best practices to ensure performance, quality, and responsiveness for mobile applications
    • Enjoys teaching and collaborating with others

An Insider's view of Citizen

What's something quirky about your company?

Citizen operates 24/7, because we’re dedicated to keeping you safe and informed around the clock. We never know when a firefighter might be called to rescue a cat from a tree, or when a wildfire might break out and quickly spread. Something unexpected is always happening somewhere.

What projects are you most excited about?

Building new tools to help everyone keep the people, places, and things they love safe, and to provide unparalleled access to help in emergencies.

How has your career grown since starting at the company?

I first joined Citizen to use technology to enhance my job as a violence interrupter, trying to stop shootings before they happen. Two years later, I am an engineer who builds hardware to enhance every violence interrupter’s job in the nation.

How do you empower your team to be more creative?

On the content team, trust and knowing you have full permission to fail is paramount to taking creative risks. We're constantly pitching, trying new things, and building off of one another's creative energy. We're a tight team, so a win for one of us is a win for all of us. Nothing like a love of collective victory to keep you striving!
