The primary assignment of the successful candidate will be the development and test environment for the ALMA Dataflow development projects. The environment supports software configuration management, continuous integration, regression testing and production of release packages for the science operations and the scientific users of ESO observatories. Finally, s/he will contribute to the Data Flow System application support activities, software configuration management issues, and to the continuous improvement of SCSEQ's development and test infrastructure. The work involves the following responsibilities:
1. Enable and optimize CI/CD practices to ensure reliable, automated software delivery.
2. Own and maintain development and test environments, ensuring stability, scalability, and reproducibility.
3. Drive automation across build, test, deployment, and release processes.
4. Embed quality controls and validation mechanisms into the delivery lifecycle.
5. Establish monitoring and observability practices to ensure system transparency and operational insight.
6. Implement fast feedback mechanisms that quickly surface build failures, performance degradation, and production risks.
7. Improve system reliability, performance, and operational efficiency.
8. Promote DevOps culture and best practices across development and QA teams.
