• Hands-on experience with containerization and orchestration technologies, including Docker and Kubernetes (AKS and Flux).
• Strong understanding of data engineering concepts, including data modeling methodologies, and practical experience with tools such as Databricks, Snowflake, Airflow, Kafka, or Kinesis.
• Alignment with our corporate culture and a commitment to integrity and ethics are highly valued;
• Strong customer focus, teamwork, task prioritisation, and daily commitment are highly appreciated.
• Excellent communication, collaboration, and problem-solving skills, with fluency in English.

What can we offer? At Aubay, we invest in your development and well-being:

• Continuous growth through our Training Academy, with technical and soft skills training, mentoring, tech communities, workshops and in-person meetups;
