About the role

As with many young companies, your responsibilities will change over time. However, here are some of the responsibilities we expect you to take on as a Senior Backend Engineer:

  • Gathering and processing large volumes of data, you'll play a meaningful role in improving a backend that processes very high volumes of raw data.
  • Supporting the rest of the team in squashing bugs and improving the quality of our main Rails application.
  • Contribute to technology strategy – we will decide together how to evolve our data processing pipeline using technologies that fit our purposes.
  • Mentor junior members in the team, e.g. by reviewing their pull requests while providing constructive feedback, helping them when they have questions, as well as more pro-active mentoring sessions.
  • Stay up to date with the latest trends in technology.


Sounds interesting? Here’s what we’re looking for:


  • You have 5+ years of experience developing high traffic web applications.
  • Strong experience with data processing, we use PostgreSQL for almost everything.
  • Knowledge of multiple programming languages. Right now we use Ruby-on-Rails, Rust, and Go with Gin.
  • Good knowledge of cloud environments, particularly AWS and DigitalOcean.
  • Strong knowledge of the fundamentals of software development – how to structure programs and decompose problems, when to apply patterns, and understand to select the right paradigm for a task.
  • Next to speaking English fluently, you are able to understand and translate business requirements into clearly articulated technology solutions.

Nice to Have:

  • Experience with stream processing tools (Apache Storm, AWS Kinesis etc.)
  • Knowledge of CI/CD systems and practices
  • Good knowledge of provisioning and orchestration tools. We presently use SaltStack and Terraform.
  • Good knowledge of Linux system administration, preferably Ubuntu.
  • Experience with Docker and service discovery layers/consensus systems (Consul, etc.)


  • Passionate about programming. You know how to run code, not just write it.
  • Pragmatic, and know when to be hands-on and enjoys taking the lead in challenging situations.
  • Excited to learn new technologies and best-practices.
  • Always up for pairing and tackling problems with your colleagues.
  • Eager to learn, contribute to design and architecture decisions, and inspire change.
