Job Description

What you’ll be doing

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 >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.

The Work

Working at Stream, 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 its deployment to production. You will also spend part of your time talking to our customers and help them to use Stream in their app.

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

Technology that powers Stream

At Stream we use a wide collection of technologies to offer highly optimized and available features to our customers. Over the years we have experimented with different programming languages, frameworks, databases, and libraries. Here’s a short list of the technology that we currently use. Don’t worry if you don’t master them all or if you don’t see your favorite tool or language, you’ll have the chance to be exposed to most and to convince us to expand the list:

  • Go, gRPC, RocksDB, Python
  • Postgresql, RabbitMQ
  • AWS, Puppet, CloudFormation
  • Grafana, Graphite, ELK, Jaeger
  • Redis, Memcached

  • Competitive salary (listed salary indications are applicable to employment in the Netherlands)
  • Company equity
  • Healthy team lunches
  • Chance to meet our team in Boulder
  • Great espresso coffee and teas
  • Office location in the center of Amsterdam
  • Be surrounded daily by a team of exceptional engineers
  • Opportunity and support to attend and/or present to industry-related conferences and meetups
  • Opportunity to work on OSS projects

Culture

Stream has a casual social culture, our team is very diverse in age, nationality and we all have different backgrounds. Our team in Amsterdam is very focused, you will see us heads-down coding or drawing complex charts on whiteboards until we pop up to have a chat or play merciless games of ping-pong.

When it comes to software engineering our culture is oriented towards ownership and quality: our goal is to deliver stable software.

Location

Our Amsterdam office is located in the TQ tech space in the heart of the city. It’s a fantastic building with all the amenities you’d expect. There’s a cafe, a shared lunch area and a sports room with table tennis and badminton.
