Twitter is what's happening and what people are talking about right now. For us, life's not about a job, it's about purpose. We feel real change starts with conversation. Here, your voice matters. Come as you are and together we'll do what's right (not what's easy) to serve the public conversation.

Who We are:

The Notifications Infrastructure (NI) team is the team responsible for the Twitter infrastructure and backend services for sending notifications to our Twitter customers, such as Android, iOS and browser push notifications, Emails, and SMS messages. In addition, the NI team is also responsible for the data (system-of-record) and respective infrastructure (storage and retrieval) for Twitter customers’ contact information, including email addresses and phone numbers. Our customers are other internal teams that need access to these fundamental APIs and functions, and we care about scalability, security and privacy at scale.

NI is part of the Notifications org, which is responsible for the end-to-end systems for all Notifications that are sent through Twitter. We are responsible for 40%+ of the top-line company user growth, and are a full-stack org with infrastructure, platform, product, relevance, and client teams.
