Data Center HPC Network Architect

Data Center HPC Network Architect
Location: Dallas, TX

Overview

This organization is backed by dedicated leadership and investment, with a clear mission as it operates at the bleeding edge of technology. Its goal is to scale and enhance high-performance computing (HPC) and cloud infrastructure that supports clients' research, production, and delivery, enabling breakthroughs that shape the industries of tomorrow. Its engineers build critical infrastructure to eliminate friction in scientific research, simulations, analysis, and decision-making, accelerating discovery and driving faster innovation.

We are seeking an experienced Backbone & Peering Network Architect to own the design and reference architecture of the data center backbone, WAN connectivity, cloud service provider on-ramps, and customer peering. This role is critical to ensuring that data centers deliver secure, scalable, and reliable connectivity at scale.

The ideal candidate will bring expertise in carrier networking, peering ecosystems, and multi-tenant network security, and will be responsible for defining the standards and architectures that ensure the backbone supports business growth, customer demand, and evolving digital services.

Key Responsibilities

- Own the architecture of the data center backbone interconnect (DCI), ensuring scalability, redundancy, and performance.
- Design and publish reference architectures for WAN connectivity, cloud service provider interconnects, and backbone extensions.
- Define architectural standards for routing, traffic engineering, failover, and telemetry across backbone networks.
- Align backbone design with capacity planning forecasts and long-term business growth.
- Collaborate with Solutions Architects to align network design with workload patterns.
- Ensure network security, compliance, and observability are embedded in architecture.
- Develop multi-tenant secure networking patterns to support customer isolation and SLA adherence.
- Contribute to digital twin models with network capacity and topology simulations.

Required Experience

- Bachelor's or Master's degree in Computer Science, Electrical Engineering, or equivalent.
- 7+ years of experience in large-scale data center network design or architecture.
- Deep expertise in data center fabrics (leaf-spine, Clos, EVPN, VXLAN).
- Experience with WAN, peering, and interconnect strategies.
- Familiarity with HPC workloads and high-bandwidth, low-latency requirements.
- Strong documentation and stakeholder communication skills.
- Experience with hyperscale or GPU-accelerated environments, supporting AI/ML workloads, infrastructure monitoring, or simulation models.
- Strong communicator with leadership and project management experience.
