We’re launching an internal incubator built for those who thrive on building something from scratch. This small, autonomous team will focus on creating a new security product with the freedom to move fast, test bold ideas, and challenge the status quo.

It’s a space for curious minds and hands-on builders – people who are driven by experimentation, comfortable with uncertainty, and excited by the idea of shaping something new from the ground up. If you’ve worked in a startup or an innovation-driven environment before, you’ll know exactly what to expect.

If you want to:

  • Architect, build, and maintain the server-side logic of the new application;
  • Lead the design and implementation of backend features and APIs using .NET/C#;
  • Focus on writing clear, tested, documented code that delivers real business value;
  • Ensure responsive and reliable service through scalable architecture


And you can check off:

  • Proven experience as a Senior Backend Developer, specifically with .NET/C#;
  • Strong understanding of OOP, design patterns, and modern .NET frameworks;
  • Experience with RESTful API design and implementation;
  • Experience in building highly scalable systems;
  • Proficiency with database design and management;
  • Background in microservices architecture;
  • Familiarity with DevOps practices;
  • Excellent problem-solving skills and attention to detail;
  • Strong communication skills and a team-oriented mindset


Here's the deal:

  • Growth and learning opportunities: time dedicated to learning, conferences, online learning platforms, and books for your professional development;
  • Health and wellness: we want you to feel and be your best. That's why we offer various benefits, from online workouts and a physical coach to health insurance and regular mental health checks;
  • Tools of your choice: choose the technical equipment and tools you need to do your best work;
  • Community and celebrations: get ready for long-lasting traditions such as yearly workation, Friday get-togethers, various team buildings and company celebrations;
  • Work-life balance: We encourage working in the office, with the possibility of up to two remote days per week. Plus, with our WFA policy, you can work from almost anywhere in the world;
  • More days off: additional vacation days depending on your tenure;
  • Premium Surfshark accounts: for you, your family, and friends;
  • Gross salary: 5000 - 7000 Eur/month. Although it may vary depending on your skills and experience.
