[Remote] Staff Engineer, Replication

Note: The job is a remote job and is open to candidates in USA. DDN is seeking a Staff Replication Development Engineer to lead the design and development of the replication engine for the Infinia AI Data Platform. The role involves building high-performance, secure, and resilient asynchronous replication systems, APIs, monitoring capabilities, and disaster recovery workflows while providing technical leadership and mentorship.

Responsibilities

• 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

Skills

• 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

Benefits

• Hybrid work arrangement
