Yelp’s DistSys teams design, implement, and maintain scalable software architectures that are at the heart of our technology.

Do you fret over consistency versus availability guarantees? Do you love making complex systems easy to use, resilient, and scalable? That’s what we do! You might have heard of one of our open source projects like data-pipeline (1) or Tron (2). Or maybe you’ve read our blog post on how we monitor Cassandra at scale (3), or watched our talk at MesosCon about our distributed task runner (4). We help enable hundreds of engineers to safely and quickly deploy their features into production while serving millions of active Yelp users.

If this sounds like you, join the team that glues Yelp’s feature teams to their underlying infrastructure"in data centers, up in the cloud, or anywhere in between.
