Big Data developer internship

Here at Sigfox we set up an analytics platform in order to allow different services to build their own data analysis. The platform is based upon a Datalake/Datamart architecture which centralises most of the company data. The aim of the internship is to improve the ETL process which populate the datalake/datamart by implementing a smart automatic schema change detection and adaptation.



As part of the Data Valorisation team, the intern will be assigned the following tasks:

  • get familiar with our current ETL process
  • design, implement and validate a Spark library for automatic schema change detection
  • study the option of publishing the library as open source project
  • write library technical documentation

Technical environment: Apache Spark, Amazon AWS, Python



Student in computer science with a specialization in big data technologies:

  • Knowledge of bigdata architectures and bigdata oriented DBMS
  • Skilled in relational algebra/model
  • Proficient in the following programming languages: SQL, bash, python.
  • Knowledge of Scala or Java would be a plus
