Careers – Software Engineer


Software Engineer (Porto, Portugal)

Velocidi is looking for Software Engineers of any level of expertise to join our team in Porto, Portugal. As a software engineer, you will join a multidisciplinary team building technology leveraging first-party data for digital marketing initiatives across channels and platforms.

Our technology is private and first-party, handles hundreds of billions of events per month, and needs to react in milliseconds. Our added value comes from the advanced marketing strategies enabled by machine learning models, which we enable across mainstream platforms such as Facebook, Google, or Mailchimp.


How we work

  • We use Scala as our main development language and our services are essentially APIs. However, we also use a variety of other programming languages for auxiliary tools and other projects, like JavaScript, Ruby, Bash, and Python.
  • We manage the infrastructure of our own systems, a process that we have automated using cloud services and orchestrators like Kubernetes.
  • We follow Agile methodologies, so we value individuals and interactions over processes and tools.
  • We know that learning takes time and resources. We will support you throughout that process.



  • Full-stack engineer with a strong grasp of large scale systems architecture.
  • Willing to work on all levels of the development pipeline.
  • Someone eager to learn new technologies and paradigms.
  • Interest in building highly scalable systems.
  • Analytical and mathematically minded.
  • Comfortable communicating in English.
