  • Help develop machine learning development framework and pipelines

  • Manage and run mission crucial production services


What we're looking for:

  • Senior level Python

  • Very good knowledge of AWS (most of it works on this), daily work in Prefect (you don't need to know it, if you know Airflow or similar, that's enough), Kafka, SQL, databases, GitLab, and k8s and Linux are on the production environment. Terraform - nice to have

  • English min. C1

• Competitive daily rate (B2B)

• Hardware & setup budget (e.g., standing desk, laptop, monitors, coworking space)
