Experience with relational or NoSQL databases, plus exposure to caching/data grid technologies a bonus.
Familiarity with cloud platforms (AWS preferred) and containerized environments (Docker, Kubernetes).
Comfortable working in Agile environments, collaborating with international teams.
Knowledge of Python is a plus, but not required.
