Key Responsibilities
Data Center & Network Architecture
- Architect and standardize modern data center network designs optimized for scale, resiliency, and performance.
- Design Layer 2 and Layer 3 architectures leveraging EVPN/VXLAN for multi-tenant, cloud-ready environments.
- Lead architecture decisions in a multi-vendor network ecosystem, with strong emphasis on Arista Networks platforms.
- Develop reference architectures, design patterns, and technical standards aligned with Arista Validated Designs (AVD) and enterprise best practices.
- Serve as a technical authority for Arista EOS-based data center fabrics, while integrating with other vendors as required.
- Design and operate network fabrics using Arista CloudVision (CVP) for centralized management, telemetry, and lifecycle operations.
- Leverage AVD to drive consistent, repeatable, and automated fabric deployments.
- Evaluate and integrate Arista solutions within a broader multi-vendor strategy to avoid lock-in while maximizing operational efficiency.
- Design network fabrics capable of supporting AI/ML training and inference workloads, including large-scale GPU clusters.
- Optimize east-west traffic, bandwidth, and latency for GPU fabrics and distributed compute platforms.
- Support architectures requiring high throughput, deterministic performance, and scalable growth.
- Collaborate with compute and platform teams to align network design with AI and GPU workload requirements.
- Enable network architectures that support private cloud platforms and cloud-like self-service consumption.
- Integrate networking into virtualization, container, and platform environments.
- Support secure and scalable hybrid connectivity between private data centers and public cloud environments.
- Ensure designs align with segmentation, Zero Trust networking, and security best practices.
- Drive automation-first networking, minimizing manual configuration and operational risk.
- Design and implement Infrastructure as Code (IaC) solutions using Python, Terraform, Ansible, AVD, or similar frameworks.
- Build reusable automation modules, pipelines, and workflows for network provisioning and lifecycle management.
- Promote declarative, version-controlled network operations across teams.
- Define and implement advanced network observability strategies, including streaming telemetry, flow data, logs, and metrics.
- Utilize Arista CloudVision telemetry and AI/ML-driven analytics platforms to detect anomalies, predict failures, and optimize performance.
- Integrate network observability into broader SRE and platform monitoring ecosystems.
- Use data-driven insights to improve reliability, capacity planning, and incident response.
- Act as a technical authority and architectural advisor for data center networking initiatives.
- Review designs, influence standards, and mentor engineers (without direct people management).
- Partner closely with cloud, SRE, security, and application teams.
- Participate in complex incident analysis and long-term architectural remediation.
- Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience.
- 8 years of experience in data center networking or infrastructure engineering.
- Deep expertise in EVPN/VXLAN-based architectures and large-scale routed fabrics.
- Strong hands-on experience with Arista EOS, CloudVision (CVP, CVaaS), and AVD.
- Experience designing networks for private cloud, AI, GPU, or high-performance computing environments.
- Proven experience with automation and Infrastructure as Code (Python, Terraform, Ansible, AVD, or equivalent).
- Strong understanding of BGP, routing at scale, network segmentation, and resiliency patterns.
- Experience designing or operating GPU fabrics or AI platforms at scale.
- Familiarity with lossless networking, RDMA, or high-bandwidth fabrics.
- Experience supporting Kubernetes, OpenShift, or cloud-native platforms.
- Hands-on experience with network telemetry and AI-driven observability tools.
- Experience integrating Arista platforms within multi-vendor data center environments.
- Strong documentation and architecture-review skills.
