Sr Product Quality Engineer jobs at Cisco in United States, San Jose

Your Impact

As an
AI Infrastructure Abstraction Engineer, you will help shape the next generation of AI compute platforms by designing systems that abstract away hardware complexity and expose logical, scalable, and secure interfaces for AI workloads. Your work will enable multi-tenancy, resource isolation, and dynamic scheduling of GPUs and accelerators at scale — making infrastructure programmable, elastic, and developer-friendly.

You will bridge the gap between raw compute resources and AI/ML frameworks, allowing infrastructure teams and model developers to consume shared GPU resources with the performance and reliability of bare metal, but with the flexibility of cloud-native systems. Your contributions will empower internal and external users to run AI workloads securely, efficiently, and predictably — regardless of the underlying hardware topology.

This role is critical to enabling AI infrastructure that is multi-tenant by design, scalable in practice, and abstracted for portability across diverse platforms.

KEY RESPONSIBILITIES

• Design and implement infrastructure abstractions that cleanly separate logical compute units (vGPUs, GPU pods, AI queues) from physical hardware (nodes, devices, interconnects) .
• Develop runtime services, APIs, and control planes to expose GPU and accelerator resources to users and frameworks with multi-tenant isolation and QoS guarantees .
• Architect systems for secure GPU sharing , including time-slicing, memory partitioning, and namespace isolation across tenants or jobs.
• Collaborate with platform, orchestration, and scheduling teams to map logical resources to physical devices based on utilization, priority, and topology.
• Define and enforce resource usage policies , including fair sharing, quota management, and oversubscription strategies.
• Integrate with model training and serving frameworks (e.g., PyTorch, TensorFlow, Triton) to ensure smooth and predictable resource consumption.
• Build observability and telemetry pipelines to trace logical-to-physical mappings, usage patterns, and performance anomalies.
• Partner with infrastructure security teams to ensure secure onboarding, access control, and workload isolation in shared environments.
• Support internal developers in adopting abstraction APIs, ensuring high performance while abstracting away low-level details.
• Contribute to the evolution of internal compute platform architecture, with a focus on abstraction, modularity, and scalability.

Minimum Qualifications:

• Bachelors + 15 years of related experience, or Masters + 12 years of related experience, or PhD + 8 years of related experience
• Experience building scalable, production-grade infrastructure components or control planes using Go, Python, and C++ ,
• Experience with Kubernetes, Docker or Kubevirt for v irtualization, containerization , and orchestration frameworks
• Experience designing or implementing logical resource abstractions for compute, storage, or networking with a focus in multi-tenant environments .
• Experience integrating with AI/ML platforms or pipelines (e.g., PyTorch, TensorFlow, Triton Inference Server, MLFlow).

Preferred Qualifications:

• Experience with GPU sharing, scheduling, or isolation techniques (e.g., MPS, MIG, time-slicing, device plugin frameworks, or vGPU technologies).
• Solid grasp of resource management concepts including quotas, fairness, prioritization, and elasticity.

This position requires a hybrid working schedule in the San Jose or Milpitas office.

As
High-performance AI compute engineer, you will be instrumental in defining and delivering the next generation of enterprise-grade AI infrastructure. As a principal engineer within our GPU and CUDA Runtime team, you will play a critical role in shaping the future of high-performance compute infrastructure. Your contributions will directly influence the performance, reliability, and scalability of large-scale GPU-accelerated workloads, powering mission-critical applications across AI/ML, scientific computing, and real-time simulation.

You will be responsible for developing low-level components that bridge user space and kernel space, optimizing memory and data transfer paths, and enabling cutting-edge interconnect technologies like NVLink and RDMA. Your work will ensure that systems efficiently utilize GPU hardware to its full potential, minimizing latency, maximizing throughput, and improving developer experience at scale.

KEY RESPONSIBILITIES

• Design, develop, and maintain device drivers and runtime components for GPU and network components of the systems.
• Working with kernel and platform components to build efficient memory management paths using pinned memory, peer-to-peer transfers, and unified memory.
• Optimize data movement using high-speed interconnects such as RDMA, InfiniBand, NVLink, and PCIe, with a focus on reducing latency and increasing bandwidth.
• Implement and fine-tune GPU memory copy paths with awareness of NUMA topologies and hardware coherency.
• Develop instrumentation and telemetry collection mechanisms to monitor GPU and memory performance without impacting runtime workloads.
• Contribute to internal tools and libraries for GPU system introspection, profiling, and debugging.
• Provide technical mentorship and peer reviews, and guide junior engineers on best practices for low-level GPU development.
• Stay current with evolving GPU architectures, memory technologies, and industry standards.

Minimum Qualifications :

• 10+ years of experience in systems programming, ideally with 5+ years focused on CUDA/GPU driver and runtime internals.
• Minimum of 5+ years of experience with kernel-space development, ideally in Linux kernel modules, device drivers, or GPU runtime libraries (e.g., CUDA, ROCm, or OpenCL runtimes).
• Experience working with NVIDIA GPU architecture, CUDA toolchains, and performance tools (Nsight, CUPTI, etc.).
• Experience optimizing for NVLink, PCIe, Unified Memory (UM), and NUMA architectures.
• Strong grasp of RDMA, InfiniBand, and GPUDirect technologies and their using in frameworks like UCX.
• Minimum of 8+ years of experience programming within C/C++ with low-level systems proficiency (memory management, synchronization, cache coherence).
• Bachelor' degree in STEM related field

Preferred Qualifications

• Deep understanding of HPC workloads, performance bottlenecks, and compute/memory tradeoffs.
• Expertise in zero-copy memory access, pinned memory, peer-to-peer memory copy, and device memory lifetimes.
