Quantum is seeking an experienced Level 3 (L3) Support Engineer to provide advanced technical escalation and sustaining engineering support for the DXi backup and deduplication storage appliance family. As a key member of the DXi engineering support organization, you will troubleshoot the most complex issues in large-scale backup environments, interface directly with Engineering, and ensure that enterprise customers achieve maximum reliability and performance from their DXi systems.

Key Responsibilities

Advanced Troubleshooting & Escalation

  • Serve as the highest-level technical escalation point for DXi systems, supporting L1/L2 technicians, field engineers, and enterprise customers.
  • Diagnose and resolve complex issues involving deduplication, replication, VTL, NAS/OST paths, multi-node configurations, performance bottlenecks, and backup application interoperability.
  • Perform deep-dive analysis of logs, traces, core dumps, replication states, filesystem metadata, and system performance metrics.

Product Defect Isolation & Engineering Interface

  • Isolate product defects, reproduce customer issues, and create detailed engineering bug reports with full diagnostic context.
  • Work closely with DXi software and hardware engineering teams to validate fixes, enhance diagnostics, and improve product stability.
  • Participate in defect triage and drive issues through resolution.

Customer Issue Resolution

  • Assist directly with high-severity incidents (SEV1/critical outages), providing expert guidance during customer recovery efforts.
  • Support complex deployments involving multi-site replication, cloud-tiering, or large enterprise backup infrastructures.
  • Collaborate with customers and field teams to optimize system configuration, dedupe performance, and backup integration.

Sustaining Engineering Responsibilities

  • Contribute to fix validation, patch testing, and release readiness for maintenance updates and new software versions.
  • Develop diagnostic tooling, automation scripts, and repeatable procedures to accelerate issue resolution.
  • Identify systemic issues and partner with Engineering to drive long-term product improvements.

Documentation & Knowledge Transfer

  • Create and maintain detailed knowledge base articles, troubleshooting runbooks, RCA documents, and internal training materials.
  • Provide mentorship and escalation training for L1/L2 support teams globally.
  • Improve internal processes to strengthen cross-team communication and support efficiency.

Operational Responsibilities

  • Participate in the on-call rotation to support mission-critical customer environments.
  • Provide input to product management on supportability, customer pain points, and field priorities.

Required Qualifications

  • 5–10+ years of experience in enterprise support, sustaining engineering, or backup/storage engineering roles.
  • Strong knowledge of backup and deduplication technologies, ideally including Quantum DXi, StoreOnce, Data Domain, or similar platforms.
  • Deep understanding of:
    • Linux internals, command-line tools, and system debugging
    • Filesystems, block storage, RAID, and multi-tier storage architectures
    • Replication technologies and WAN optimization considerations
    • Backup application integration (NetBackup, Commvault, Veeam, TSM/Spectrum Protect, etc.)
  • Strong understanding of network protocols (TCP/IP, NFS, CIFS/SMB, FC, iSCSI, OST, VTL).
  • Proven ability to analyze large volumes of logs and correlate multi-component events.

Preferred Qualifications

  • Hands-on experience with DXi appliances, Quantum backup workflows, or deduplication algorithm fundamentals.
  • Knowledge of cloud storage integration (AWS, Azure, S3-based cloud tiering).
  • Familiarity with scripting languages such as Python, Bash, or PowerShell for test automation or tooling.
  • Experience working directly with software engineering teams or in a sustaining engineering environment.
  • Relevant certifications: RHCE, Linux+, Storage+ or backup vendor certifications.

Soft Skills

  • Strong communication skills for interaction with enterprise customers, engineering, and management.
  • Calm, structured problem solver during critical incidents and high-pressure situations.
  • Collaborative team player who can influence and guide cross-functional support discussions.
