Who You Are
Strong, proven experience with containerisation, Python, and CI/CD in a production ML environment.

Expert experience working with streaming data and high-volume data processing at scale.

Ability to quickly switch between complex technical implementation and value-focused discussions with data scientists (a consulting mindset).

Demonstrated experience in architecture design and taking ownership of large-scale ML infrastructure.

Experience with GCP and Kafka streaming is a strong plus.

Scientific and critical thinking skills, combined with the ability to present your ideas clearly and compellingly.

A friendly and helpful personality, open to give and receive feedback in a constructive way.

Motivation to push yourself and the people around you to constantly improve and define the technical roadmap.
