Senior Quality Assurance Engineer

Quantum; Centennial (CO); Hybrid; USD 110,000 - 165,000; Full time

Job summary

Quantum is seeking a Senior QA Engineer to own quality across the Unified Surveillance Platform (USP). You’ll operate hands-on in a physical hardware lab, validating high-availability infrastructure and VMware environments from the rack up.

Ideal candidates bring 5+ years of infrastructure QA, strong VMware expertise, and proven lab ownership. Hybrid work at our Centennial lab is required, with onsite collaboration and cross-team testing leadership.

Qualifications

• 5+ years of senior, hands-on infrastructure or solutions QA experience, not application/web QA.
• Deep, current VMware expertise: vSphere, ESXi, HA, DRS, vMotion/live migration, administered and tested.
• Physical lab ownership experience, primarily Linux, with Windows Server exposure a plus.
• Solid grounding in storage-networking concepts: iSCSI, RAID, VLANs, block vs. file storage.
• Track record of owning test strategy, not just executing test cases: release-readiness judgment.

Responsibilities

• Design, execute, and own test strategy for USP releases, including test plans, test cases, execution reporting, and release-readiness sign-off from end to end.
• Build and run deep validation of VMware vSphere/ESXi environments, including HA, DRS, and live‑migration failure and recovery scenarios.
• Own and maintain a physical test lab (primarily Linux-based, with Windows Server systems where needed), covering hardware, virtualization stack, and everything in between.
• Validate storage‑networking fundamentals underneath the platform: VLANs, iSCSI, RAID/erasure coding, and block vs. file storage behavior.
• Partner with engineering to reproduce, triage, and drive resolution of complex infrastructure defects.
• Bring surveillance‑domain awareness to testing; familiarity with VMS platforms (Milestone, Genetec, Avigilon, or similar) is a strong plus.

Job description

About the role

Quantum is looking for a Senior QA Engineer to own quality across our Unified Surveillance Platform (USP), a hyperconverged, VMware-based storage platform purpose-built for enterprise video surveillance. You'll be the technical backbone of our test strategy, working hands‑on in a physical hardware lab to validate high-availability infrastructure that our customers depend on to keep critical surveillance systems running without interruption.

This is a senior, hands‑on role for someone who’s spent real time inside VMware environments, not just deploying to them, but administering, breaking, and hardening them, and who’s comfortable owning a physical test lab from the rack up.

What you’ll do

• Design, execute, and own test strategy for USP releases, including test plans, test cases, execution reporting, and release-readiness sign-off from end to end.
• Build and run deep validation of VMware vSphere/ESXi environments, including HA, DRS, and live‑migration failure and recovery scenarios.
• Own and maintain a physical test lab (primarily Linux-based, with Windows Server systems where needed), covering hardware, virtualization stack, and everything in between.
• Validate storage‑networking fundamentals underneath the platform: VLANs, iSCSI, RAID/erasure coding, and block vs. file storage behavior.
• Partner with engineering to reproduce, triage, and drive resolution of complex infrastructure defects.
• Bring surveillance‑domain awareness to testing; familiarity with VMS platforms (Milestone, Genetec, Avigilon, or similar) is a strong plus.

What you bring

• 5+ years of senior, hands‑on infrastructure or solutions QA experience, not application/web QA, but real infrastructure testing.
• Deep, current VMware expertise: vSphere, ESXi, HA, DRS, vMotion/live migration, administered and tested, not just deployed onto.
• Physical lab ownership experience, primarily Linux, with Windows Server exposure a plus.
• Solid grounding in storage‑networking concepts: iSCSI, RAID, VLANs, block vs. file storage (experience with NetApp, Dell, Hammerspace, or Cumulo‑comparable environments a plus).
• A track record of owning test strategy, not just executing test cases: release‑readiness judgment, not just defect logging.
• Based in or willing to work a hybrid schedule (3 days/week onsite) at our Centennial, CO hardware lab.

Why Quantum

USP powers surveillance storage for organizations who can’t afford downtime. This is infrastructure QA with real stakes, on hardware you can walk over and touch. If you’d rather be hands‑on in a lab than buried in tickets for a web app, this is that role.
