Replication Development Engineer

Staff Replication Development Engineer

DDN is seeking a Staff Replication Development Engineer to lead the design and development of the replication engine for the Infinia AI Data Platform. This role focuses on building enterprise‑grade asynchronous replication capabilities that enable reliable and secure disaster recovery for large‑scale data systems, requiring deep expertise in distributed systems and strong technical leadership to deliver a scalable and resilient replication foundation.

• Design and develop multi‑threaded asynchronous replication systems with parallel streaming capabilities
• Build object‑level delta replication with checkpointing and resume functionality
• Develop replication engines supporting bucket/share‑level replication controls
• Implement secure data transfer mechanisms using TLS 1.3 with mutual authentication
• Ensure end‑to‑end data integrity through checksum validation and verification pipelines
• Design and implement manual failover workflows for disaster recovery scenarios
• Build and maintain REST APIs for replication configuration, control, and automation
• Develop metadata tracking and change detection systems to enable efficient replication
• Implement RPO visibility, alerting, and operational insights for replication status
• Contribute to monitoring dashboards focused on replication health and performance
• Ensure systems are designed for high availability, fault tolerance, and scalability
• Partner with QA teams to drive performance, resiliency, and scale validation
• Collaborate with backend, security, and platform teams to deliver end‑to‑end replication workflows
• Participate in debugging, production issue resolution, and continuous improvement of replication reliability
• Provide technical leadership, architectural guidance, and mentorship to the engineering team

• 8+ years of experience in distributed systems, storage systems, or backend software engineering
• Strong programming skills in one or more languages: C++, Go, Java, or Rust
• Experience designing and building data replication systems, data pipelines, or distributed data services
• Deep understanding of distributed systems concepts (consistency, availability, scalability, fault tolerance)
• Strong expertise in multi‑threading, concurrency, and parallel processing
• Knowledge of networking protocols and secure communication (TCP/IP, HTTP/HTTPS, TLS)
• Experience implementing data integrity mechanisms (checksums, validation, consistency checks)
• Experience designing and building REST APIs and service‑based architectures
• 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

• 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
• Experience building high‑throughput, low‑latency data movement systems
• Exposure to security practices including mutual TLS, encryption, and authentication
• Experience working on enterprise‑scale data platforms or storage products
• Familiarity with performance optimization and large‑scale system tuning
