About Stream

We power experiences for over half a billion users with our Feeds API & Messaging API.

Leverage Stream's Feed API to build the most engaging activity feed without worrying about the underlying storage technology. Advanced features such as aggregation, ranking, real-time and personalization enable your product team to optimize your app’s engagement and retention.

Position

Stream is looking for a full time, onsite Backend Software Engineer to join their development team. Job duties will include working on Stream's core API technology as well as designing and building high-performance software.

Most of your day will be dedicated to software design, research, and coding. On typical projects, you will have a lot of freedom and you will be paired with another team member. Our team is made up of very experienced engineers, some with more than 10 years of experience. By working together you will learn from each other along the way. You will have an enormous impact on making our API service faster, more scalable and more flexible.

You will add new features to the service and find ways to make the existing ones perform orders of magnitude faster. Our customers have millions of users; they use Stream for mission critical features such as showing content and exposing core functionality of their application. Building stable and reliable software is not just an option: as a member of the development team, you will design and write state-of-the-art software, follow best practices, measure everything and be responsible for deployment to production. You will also spend part of your time talking to our customers and help them to use Stream in their app.

The challenges

• Distributed databases: we built our own data store for feeds and for chat
• Real-time messaging
• High performance: our API responses are in the 10ms range
• High scalability: we use sharding, master-master, and master-slave to ensure scalability
• High availability: our entire infrastructure is designed and operated to survive entire datacenter crashes
• Multi-region: we deploy our service on 4 different continents

• 5+ years as a backend developer
• Experience with high traffic and high performance applications
