Summary

Wikimedia’s JavaScript code is executed over half a billion times a day on hundreds of millions of devices. If you can drop our page load time 100ms, you’ll have saved our annual visitors from waiting an aggregate 617 years.

Speedis Wikipedia’s killer feature. (‘Wiki’ means ‘quick’ in Hawaiian.) As the nonprofit organization that runs Wikipedia and its sister projects, we want to create value for readers and editors by making it possible to retrieve and render content at the speed of thought, from anywhere in the world, on the broadest range of devices and connection profiles.

If you are excited by this mission, we want to hear from you. The Wikimedia Foundation is looking for a web performance engineer to join a new team dedicated to making Wikipedia fast.

Description

• Work in a small team.

• Set standards for performance and responsiveness across Wikimedia engineering.

• Leverage new web APIs and network protocol extensions to speed up content delivery and interface responsiveness across mobile and desktop.

• Develop benchmarking and observability tools that help developers understand the performance characteristics of their code.

• Curate and maintain a set of key performance indicators for core features.

• Profile, analyze and optimize the performance of existing code.
