We are seeking a high-caliber Senior HCI Software Engineer to join our Hyperconverged Infrastructure Team. In this role, you will be responsible for the core software stack that unifies compute, storage, and networking into a single, seamlessly managed platform: the HCI Software Stack. You will design, implement, and optimize the software layers that converge compute, storage, and networking resources into a unified, policy-driven infrastructure platform.

This is a full-stack infrastructure role requiring a passion for systems software, distributed resource management, and building platforms that make complex infrastructure easy to operate at scale.

Specific duties include but are not limited to:
- HCI Platform Architecture: Design and maintain the core HCI software stack including the distributed resource scheduler, software-defined storage engine, and virtual networking fabric that underpin Quantum's hyperconverged appliances.
- Performance & Resource Efficiency: Profile and optimize resource contention across compute, storage, and network layers.



Work with technologies like iSCSI, NVMe-oF, SR-IOV, and DPDK to minimize overhead and maximize workload density on shared HCI nodes.
- Fault Tolerance & Self-Healing: Implement and maintain features such as automatic node failure detection, live VM migration, distributed snapshot management, and self-healing storage policies to ensure continuous availability of HCI workloads.
- Virtualization & Workload Management: Develop and extend integrations with hypervisors (KVM, VMware, Hyper-V) and container runtimes (Kubernetes, Docker) to enable seamless workload placement, live migration, and QoS enforcement across the HCI cluster.
- Scale-Out & Lifecycle Management: Ensure the HCI platform scales linearly as nodes are added, automating data rebalancing, capacity expansion, and rolling software upgrades without disrupting running workloads.

Job Requirements:
- Minimum 8 years of experience in systems or infrastructure sof
