Job Description

We are the Community Notes team — empowering the people to keep each other better informed, with a fully open source algorithm and data. Community Notes is constantly advancing the state-of-the-art in improving the quality of information on the internet and we employ an experimental, fast-moving, iterative approach to find product solutions that work for people of all different points of view.

What You’ll Do:

Build. Build. Build. Build new, core functionality that makes Community Notes better — if you’d been here last year, here are a few (of many) examples you might have helped build:

• Media notes, which automatically show notes on posts that contain matching media

• Making notes appear way faster by moving our scoring system to real-time streaming infrastructure

• Notifications to people who engaged with a post before its received a note

• Note previews that can significantly improve note quality by quickly gathering ratings on promising new notes

• … and many more … we shipped >1 product update per week on avg through 2023

• Architect and deliver new systems with a high degree of autonomy. Your small group of very senior teammates will provide input, yet will be entrusting you to design systems that will be performant, scalable and reliable

• Work across the X stack to build the highest impact product improvements. For example, in addition to our distributed serving and storage systems, you might work with media clustering systems, trust & safety or ads systems, Grok AI, or client apps (web/Android/iOS).

• Shape the roadmap of Community Notes as part of a small, highly capable team, everyone of whom is deeply familiar with the product.

Qualifications:

• Proven experience building and operating software services at scale

• Great understanding of writing performant backend code in a distributed systems environment

• Bonus but not required: Experience with client engineering (web, iOS and/or Android)

• Bonus but not required: Experience with modern data pipeline and ML infrastructure

• Enjoy working in a 0-to-1 space with no known machine learning or product solutions, and trailblazing to build novel solutions that work

• Love doing whatever work is needed to get things done, enabling rapid iteration on the product

Join our small, but mighty team and empower the people to keep each other better informed.

If you thrive in a dynamic, high-growth tech environment and relish the opportunity to collaborate with passionate, driven over-achievers, your career with us here at X will be both exhilarating and fulfilling!
