Senior Software Engineer Hyperconverged Infrastructure Data Path

Quantum Corp. leads the world in helping organizations build modern software-defined infrastructure that simplifies IT operations and accelerates digital transformation. Whether its delivering unified compute storage and networking for enterprise workloads enabling seamless hybrid cloud deployments powering mission-critical virtualized environments or driving AI-ready hyperconverged infrastructure at scale Quantum has the tools and technology to help you engineer the solution that works now - and scales for decades to come. You are applying to an exceptional team that contributes to enhancing our position as a proven global leader in hyperconverged and software-defined infrastructure.

We are seeking a high-caliber Senior HCI Software Engineer to join our Hyperconverged Infrastructure 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 simple 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 Quantums 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 software development using C/C Python or equivalent languages.
• Leverage modern development tools and AI-assisted workflows (e.g. Claude code GitHub Copilot Cursor LLMs) to accelerate prototyping code generation and test automation.
• Experience developing or optimizing the datapath in a software-defined storage layer including I/O path caching replication erasure coding and low-latency data services.
• Experience with hypervisors (KVM VMware vSphere Hyper-V) and container orchestration (Kubernetes OpenShift) is a plus.
• Experience with software-defined networking (OVS VXLAN BGP) and Linux networking stack is a plus.
• Experience with HCI platforms such as Nutanix AOS VMware vSAN or Azure Stack HCI is a plus.
• Experience with AI/ML infrastructure workloads and GPU resource management is a plus.
• Ability to work in a team environment.
• Strong communication skills.
• Ability to work with a globally distributed team.
• Self-motivated able to identify and solve problems on their own.
• Ability to collaborate cross functionally and integrate other components into the solution.
• Approach problems creatively and not just repeat the same mistakes made before them.
• Effective communicator to both technical and non-technical audiences.

Desired Skills:

• Experience with Linux OS administration including kernel tuning performance profiling (perf eBPF) and HCI node lifecycle management
• Experience using GIT.
• Experience using JIRA.

Ideal Candidate:

Our ideal candidate is passionate about simplifying infrastructure complexity thrives at the intersection of hardware and software and has hands-on experience designing or operating hyperconverged or software defined infrastructure environments.
