  • Strong problem-solving skills and the ability to debug complex systems independently
  • Self-motivated, reliable, and effective when working asynchronously without close supervision
  • Clear communicator who can document decisions and collaborate across time zones

Nice to Have

  • Experience building infrastructure for machine learning or AI systems
  • Familiarity with data processing frameworks (Apache Kafka, Spark, Airflow, or similar)
  • Background in performance optimization, caching strategies, or high-throughput systems
  • Knowledge of authentication, authorization, and security best practices
