Company Description

What is the Job:

Staff Software Engineer. This role will build and operate critical Product Platform layer content delivery services of Twitter, including the Home and Profile Tweet timelines.

Why it Matters:

The Timelines Infrastructure team is responsible for the leading edge of Twitter’s Product Platform, which the User Experience is built upon, and which defines the future of how Twitter product development happens. Among many things, we create the API and infrastructure that powers the Home Timeline - the Tweet feeds our customers interact with every day. We are reinventing critical parts of that stack, and you can be a part of it.


Who we are:

Twitter serves the public conversation by encouraging people all over the world to connect, learn, debate, and solve problems together. Joining the team today means you’ll make the conversations of tomorrow possible. It’s not always easy, but nothing worth doing ever is.

The Timelines Infrastructure team creates the delivery platform powering the intersection of content, users, and the environment they’re in. It is the logistics layer for content at Twitter, handling the flow of core Twitter content from between the point of creation and the point of consumption. Timelines Infrastructure is also responsible for the perspectival serving of Twitter content - that is, we own the relationship between content and users.

We support most product development at Twitter, constantly looking out for patterns to generalize, so we can then offer new platform and infrastructure primitives that support reliable and resilient new product features. These primitives manifest as high scale external public and private APIs, as well as internal APIs and infrastructure that form much of the core product infrastructure for Twitter.

Additional Information

We are committed to an inclusive and diverse Twitter. Twitter is an equal opportunity employer. We do not discriminate based on race, ethnicity, color, ancestry, national origin, religion, sex, sexual orientation, gender identity, age, disability, veteran status, genetic information, marital status or any other legally protected status.
