Senior Python Expert

Job description

About the Role

We're looking for a Senior Python Software Engineer (Contractor) to join a large-scale digital platform program in the European energy sector. The project focuses on building a cloud-native platform that enables software teams to efficiently develop, deploy, and operate applications across hybrid cloud environments.

Identify and implement improvements to tools, workflows, and engineering practices.
