Proxyclick is a rapidly growing tech company based in the heart of Europe. Our mission is to help businesses better manage their visitors well beyond the simple act of registration. We incorporate into the visitor experience notions of security, health and safety, brand promotion and communication, and privacy.

Our cloud-based SaaS visitor management solution caters to the enterprise security needs of companies such as Airbnb, Audi, Dimension Data, L’Oréal, or Pepsico. Millions of people around the world use our apps.

In everything we do, we strive to build the best possible product. Our goal is to combine simplicity and power to deliver an awesome experience.

We’re looking for an experienced C# Developer to join our EU team in our project office in Rotterdam.

Roles and responsibilities

Your priority will be to implement secure, reliable, and scalable solutions along with a number of exciting initiatives:

  • Working with the C# back-end team to manage and deploy integration platforms to manage access to buildings
  • Improving our technical architecture by finding and addressing performance issues and rewriting legacy code for better scalability and high availability
  • Growing our portfolio of integrations available on our Marketplace by implementing connectors with Access Control Systems

Finally, because your work is not only about writing code, you will be collaborating with our customer success team to solve complex issues and fix bugs


  • You possess strong computer science fundamentals: data structures, algorithms, programming languages, distributed systems, and information retrieval
  • You understand the importance of building structured code that is crystal-clear, fast, scalable, reliable and robust
  • You have extensive practical experience with C#
  • You have a working experience of React or Angular

  • You have a solid understanding of the full web stack (e.g. TCP/IP, HTTP, cookies, headers, asset loading / caching)
  • You pay attention to the details and possess amazing debugging skills

We don’t need you to be familiar with all of these technologies to start working with us. Great people learn what we use quickly (and introduce us to new technologies too)

Your personality:

  • A team player with a positive attitude that others trust and enjoy working with.
  • A critical thinker who embraces their role as part of a larger team outside of IT.
  • A hacker who’s comfortable with ambiguity and technical challenges
  • A hustler who finds creative ways to solve problems and prototype in the shortest time frame
  • A doer that just gets it done with the ultimate objective being customer success!


  • The opportunity to have a direct impact on an exciting project with global reach
  • A great experience in state-of-the-art web technologies
  • Competitive compensation including stock options
  • A nice working atmosphere, surrounded by a passionate team
  • Flexible working time and possibility to work remotely
  • International culture and learning atmosphere

  • We set our hiring bar really high—you will be working with the best
