    • Experience in distributed processing frameworks (Spark, etc.)
    • Experience with Streaming technologies (Kafka, Kinesis, etc.)

What we offer:

    • An opportunity for personal and professional growth, supported by high functioning teams, stellar investors and the exciting challenges that come with joining a company at the start of its growth trajectory;
    • An environment free of bureaucracy and corporate constraints; a culture where your opinion is highly valued and appreciated;
