About the role
We are looking for engineers who build infrastructure software from scratch, not those who operate it. If your core expertise is configuring, managing, scaling, or writing applications on top of existing data platforms like Kafka, Flink, Spark, Databricks, or Snowflake, this role is not the right fit. We are seeking the engineers who can write the code that replaces these tools.
