Job description

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.

Responsibilities

• 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 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.
