Collaborate with platform teams, ML engineers, and service owners to identify pain points, reduce fragmentation, and improve infrastructure reliability and performance
Implement and evolve practices around automation, observability, CI/CD, and infrastructure security
Stay hands-on with emerging cloud-native technologies and drive their adoption where relevant (e.g., CNCF tools, open source frameworks, Google Cloud services)
Work in Python-based environments, contributing to the stability and scalability of ML-native workflows, pipelines, and orchestration systems
Contribute to knowledge-sharing, code reviews, and documentation practices that strengthen the team’s effectiveness
Understand and promote the principles of platform engineering
