As a solution architect, you have the ability to grasp the complexity associated with modern platform solutions, and break it down into simpler, understandable bits towards both engineers as well as business stakeholders. You're able to facilitate the architectural processes, identifying desired qualities and constraints, ensuring risks and trade-offs are discussed within the team(s) and guiding business stakeholders to take informed decisions.


  • It's your responsibility to ensure that the architecture of the products you're assigned to is sound, well-understood and continues to evolve in a direction that best support the business case.
  • To a great extend, that means facilitating the architectural debate, ensuring the architectural decisions are made consciously and its trade-offs (or derived risks) are well understood, both internally (towards the involved teams) as externally (towards our client's stakeholders).
  • You're a reliable partner for your solution design colleagues during the knowledge handover, creation & validation of their designs.


  • Master in Informatics or Master in Computer Science (or related) or equivalent by experience
  • You have at least 5 years of relevant experience as a software engineer and a solution architect
  • You're familiar with the principles, opportunities and challenges of modern architectural paradigms and you know how to apply them.
  • From a technical point of view, you have a broad knowledge in terms of technologies; allowing you to collaborate efficiently with experts while being able to assess the impact of a technological choice on the architectural design. Amongst others, this includes:
    • Docker and Kubernetes
    • Databases systems (relational, document, key/value, graph, search, datawarehouse,..) and data engineering frameworks
    • Messaging & eventing systems
    • Connectivity & networking concepts
    • Communication protocols and technologies (HTTP, WS, REST, OAuth, OIDC, SAML, graphql,...)
  • You're familiar with the challenges posed by creating secure software and how to manage them
  • You've got proven experience with common software engineering practices (SDLC, devops,... ) and architecture modelling practices (UML, EER, Swagger... ).
  • You’re always keen to learn new things, share your knowledge, embrace change and learn from past experiences. Drawing on a whiteboard to facilitate a debate comes natural to you.
  • You’re able to work in a team and are always open for feedback from your team mates.
  • You have an affinity with product design and engineering top-notch digital products.
  • You’re able to handle the pressure and flexibility of a dynamic company.
