This position is based in Paris.

We are excited to meet you if:

• You have 3 to 5 years of professional experience in Data Engineering or Python development with a strong focus on data processing.

• You are proficient in Python and Spark .

• You are a proactive "doer" : we are looking for someone autonomous and mature who takes ownership of subjects rather than waiting for instructions.

• You ensure code quality by following software engineering best practices, including Continuous Integration and automated testing.

• You are familiar with orchestration tools , and having experience with Airflow is a significant plus.

• You are driven by efficiency and resilience , capable of building systems that stay performant under heavy loads (500k events/sec).
