The role:

You’ll be responsible for delivering amazing user experiences of our Online Seminars! As full-stack developer, you’ll develop exciting new products for a wide variety of client challenges, such as highly interactive webinars using the next generation of streaming technologies.

You are the spider in the web when building applications and websites. You will be working with small but agile teams and are involved right from the concept phase! And because you work with the frontend, backend, and everything in between, you can use your knowledge and creativity across the board. This means you co-create closely with other developers from the IT development team, as well as with our product owners and application managers. This allows you to mediate between the various specialists in a project.

  • Support in the development of products such as web portals, CMS / customer management tools / customer-specific extensions
  • Contribute to the overall quality through conducting code reviews and advising colleagues
  • UX sessions with the customer
  • Actively cooperate and manage the sharing and improvement of knowledge within the team

The ideal candidate:

  • Academic work- and thinking level
  • Education in Computer Science or similar
  • Knowledge of Agile/SCRUM
  • Good knowledge of C# .NET and the use of frameworks (EF, ServiceBus, e.g.)
  • Good understanding of different architectural approaches and their application to a platform (keywords: cost, impact, transition, patterns, best practices, principles)
  • Strong in building and maintaining quality, both code & architecture
  • You are able to fulfill an advisory role (and feel comfortable doing so), both internally (team, management) and towards clients during project initiation.
  • Experience with frontend frameworks such as React or Angular
  • Good communicative skills

The following qualities are nice-to-have’s:

  • Experience with integrations (e.g. authentication, mail, logging platforms, etc.)
  • Experience with applying test tools and methodologies
  • Setting up/managing DevOps pipelines
  • Coaching qualities

Can we make you happy with:

  • Working at a prime location in Amsterdam
  • A personal development plan and following training courses
  • A salary that matches your work experience
  • 24 vacation days in a year
  • A laptop and telephone reimbursement
  • Hybrid working
  • A free lunch, which you can compose according to your own lifestyle
  • Padel is very hot here, but feel free to bring up your own activity
  • Regular parties & get-togethers, organized by a number of enthusiasts
