Principal Python Engineer - Portugal Full Remote

Principal Python Engineer - Portugal Full Remote
ABOUT THE OPPORTUNITY
This is a Principal-level role for a Python engineer who has built a career on Python and now shapes how engineering organisations design, build and run software. You will set technical direction, define the standards other teams follow, and act as a trusted technical voice for engineers and non-technical stakeholders alike. If you enjoy large-scale challenges and leading through expertise rather than hierarchy, this is a role where your experience will have visible impact.
PROJECT & CONTEXT
You will join a major retail organisation working on large-scale projects. As Principal Python Engineer, you will align architecture with organisational strategy and communicate complex designs clearly to diverse stakeholders. Across multiple teams, you will drive the adoption of technologies and best practices, raise the bar on testing and quality, and guide security, performance and observability. You will also improve how software is built, deployed and supported in production, and drive continuous improvement in Agile delivery. The focus is on Principal-level software engineering in Python. Infrastructure experience is a strong advantage, but it is not the core of the role.
