Senior Python Developer / DevOps CI/CD Engineer

Project overview

Experience: 8 years minimum

Focus: Python Development / API & CI/CD Platform Administration

Seniority: Senior / Technical Expert

Context:

As part of the industrialization and continuous improvement of its continuous integration platforms, we are looking for a Senior Python Developer with solid expertise in CI/CD tool administration.

The consultant will be involved in the development of automation services, technical administration of CI platforms, and their integration within the DevOps ecosystem.

The position requires a dual skill set: excellent command of Python development, particularly for REST API design, and significant experience in the administration, configuration, and operational maintenance of CI/CD solutions.

This is not a role for a mere user of CI/CD tools, but rather a technical administrator and developer of automation solutions.

Main Missions

Ensure the technical administration and operational maintenance of the following solutions:

GitLab CI and/or Jenkins

JFrog Artifactory

SonarQube

JFrog Xray

Profile Sought

Minimum experience: 8 years, with significant experience in software development and DevOps environments.

We favor a profile from Python development, who has progressively acquired true expertise in CI/CD platform administration.

Essential Skills

Complementary Skills Appreciated

Expected Qualities

Differentiating Criteria

The ideal candidate is above all a senior Python developer capable of designing complex APIs and automation tools, while being comfortable with CI/CD platform administration activities.

Limited experience in writing GitLab CI or Jenkins pipelines, publishing artifacts in Artifactory, or operating SonarQube reports will not be sufficient.

The ability to administer, configure, maintain, and automate these platforms is an essential selection criterion.
