An internship in Krakow contributing to enterprise software (DELMIA) development with .NET, C#, REST/gRPC, Git, and CI/CD, while learning application security hands-on through secure code reviews, threat modeling, and SAST/SCA/DAST tooling, with a path toward a Security Champion role.
We are looking for a motivated Software Developer Intern who wants to grow at the intersection of software engineering and cybersecurity. You will join an R&D engineering environment and contribute to the development of enterprise software while working closely with our Application Security team and Security Champions.

Write and maintain unit and integration tests to ensure robust, clean, and reliable code.
Conduct technical research and spikes to help solve complex platform challenges.
Actively participate in team agile ceremonies, code reviews, and daily operations, working with Git and CI/CD pipelines.
Contribute to secure code reviews, threat modeling, and the definition of security requirements for new features.
Support the analysis and triage of vulnerabilities using SAST, SCA, and DAST tooling.
Get involved in security testing of APIs and services, as well as authentication, authorization, and cryptography topics.
