About the intership

Interested in building real-world software skills and learning from experienced mentors? Spyrosoft’s internship program is back! After the success of our previous programs, we're excited to welcome a new group of interns this year.

Our summer internship program is designed as a project-oriented experience where students, with the support of our experienced mentors, have the opportunity to work on challenging and engaging topics. At the very beginning, each student goes through a structured onboarding process — similar to the one our new employees complete — to get familiar with our working environment and the processes within Spyrosoft as an international organization. 

Together with their mentor, students define the topic and project they will work on during the internship, based on their preferences and previous knowledge. The internship typically concludes with a short presentation where students showcase the progress and results of their work. Each student both receives and provides feedback about their internship experience.

At Spyrosoft, we’re committed to supporting young talent, encouraging growth, and creating space for fresh ideas to thrive. Want to know what it’s really like? Check out interviews with past interns from the summer of 2023 and summer of 2022.
