  • Work with data scientists and analytics engineers to support experimentation and measure performance.
  • Participate in code reviews and collaborate on best practices with your engineering peers.

QUALIFICATIONS:

  • Professional backend engineering experience in a production environment.
  • Proficiency in building APIs and working with relational databases (e.g., RESTful APIs, Postgres).
  • Experience with event-driven systems and asynchronous processing tools such as Kafka or SQS.
  • Skilled in writing comprehensive tests and clear documentation.
