  • Familiarity with checkpointing, failure recovery, and retry mechanisms in distributed systems
  • Basic understanding of observability concepts (metrics, logging, alerting)
  • Strong debugging, problem-solving, and system design skills

Preferred Qualifications

  • Experience with asynchronous replication, disaster recovery (DR), or backup systems
  • Familiarity with object storage or large-scale data storage systems
  • Knowledge of delta encoding, change data capture, or incremental data synchronization techniques
