As part of this internship, you will be involved in software development activities within an experienced team of 10 to 12 people spread between Rungis and Toulouse. The internship aims to design and industrialize an automation chain (scripts + CI/CD) to compare Java artifacts (JARs), in order to strengthen the confidence, traceability, and reproducibility of these. The internship consists of developing an automatic binary comparison tool to guarantee the reproducibility and reliability of software builds within Thales development environments.

Your missions:

• Develop a tool capable of automatically comparing Java binary files (JARs), executable locally and in GitLab CI.
• Participate in the analysis of existing mechanisms and define the scope of the MVP.
• Create and test Python/Shell scripts to compare two JARs and generate exploitable results.
• Integrate these scripts into a GitLab CI/CD pipeline to automate execution.
• Set up analysis reports (HTML, JSON) to ensure traceability and audit.
• Test the solution on real cases to validate its reliability.
• Write technical documentation and propose improvements for large-scale integration.

Your profile:

You are in your final year of computer engineering school, university, or equivalent (BAC+5) in the field of software development and are looking for a 6-month internship.

You have the following skills:

• Bash/Python scripting for automation, proficiency in Linux and Git, knowledge of CI/CD pipelines (GitLab CI), compilation of Java projects (Maven/Gradle) and JAR structure.
• Unit testing, report generation and parsing (HTML/JSON), Docker containerization, basic reading of Java artifacts.
• Technical curiosity, rigor, autonomy, and initiative, teamwork.

A word from the team:
