  • A healthy mix of green field initiatives and established (yet recent) codebases
  • A refined operating model that prioritises technical excellence
  • Company-wide initiatives to continuously optimise our technical setup

We’ll expect you to be a constructive team player in a specific product team, while also contributing to our technical principles across all back-end-end activities. You grasp the product development process, underpinned by modern operational delivery principles. On a daily basis you'll assess product objectives and turn user stories into functioning software together with our front-end engineers.

Core role:

APIs: fundamentally grasp the mechanisms of REST APIs and you have a solid understanding of alternatives approaches (GraphQL and others)

  • Knowledge of the differentiators between relational / non-relational DBs


  • Technical design: drawing up conceptual architectural schema’s
  • Data modelling: ability to be part of database schema discussions
  • Heavy load: a notion of stress testing principles and performance at scale

Continuous integration: experience with continuous integration tools like Github actions, Azure pipelines or CircleCi


  • Hands-on experience with GCP, AWS or Azure in a production setting
  • Cost calculation considerations


  • Unit tests: covering small fractions of the code in an efficient manner
  • Integration tests: grasp and cover full application flows
  • Test coverage tracking: keeping oversight over coverage and quality

As a plus:

Data management and engineering:

  • Data migrations: experience with complex data migrations and transfers
  • Preprocessing: assisting others in setting up proper data pipelines
  • Data science affinity: understanding of data-driven use cases

Front-end affinity: you have an in-depth understanding of the inner workings of a front-end application and you can tailor the API endpoints towards maximum efficiency

We offer

We offer a friendly, dynamic and inspiring working and learning environment with a strong team ready to help out where needed. During our weekly Panenco Labs sessions, we share experiences from the various products that we're building across different specialty domains.
