Our teams work on the infrastructural layers of the app - the core frameworks, APIs, and tools that empower our feature engineers to do their best work. We solve complicated problems that are unique to both the scale of our customer base and the size of the engineering organization we support.
A few things that set us apart:

  • We ship - we are big fans of the build-measure-learn cycle with a weekly release cadence.

  • Team-centric development - we are strong believers of limiting our work-in-progress and bias towards working collaboratively.

  • We value software quality and technical growth - our code runs on millions of devices every single day, so it needs to be stable, performant, and trustworthy.

Within Client Foundation, you will be responsible for building infrastructure and abstractions to help us double our engineering velocity. You will use your creativity, excellent problem solving, and technical skills to enable Twitter to reach every person on the planet.

You will work at all layers of the stack and closely with partners across engineering, data science, research, product, and design. You will help our codebase stay ahead of the curve of the constantly evolving development ecosystem and will ensure that feature development at Twitter is both fast and fun.

  • Architecture - We build frameworks and infrastructure to make product development faster, safer, and more consistent. Our work has a wide breadth and takes us all over the codebase. Our customer focus has us working really closely with just about every other mobile team in the company.
