Lead Infrastructure & Networking (Houston, TX - Hybrid) About Submer

Submer designs and delivers end-to-end AI datacenter infrastructure built around industry‑leading liquid cooling.

We help organizations scale AI beyond the limits of traditional datacenters by enabling higher density, greater efficiency and lower environmental impact – accelerating time-to-AI from first deployment to full production.

Submer is seeking an experienced and highly hands‑on Lead Infrastructure & Networking to lead the architecture, deployment, operational strategy, and scaling of networking and infrastructure platforms supporting next‑generation AI, hyperscale, cloud, and modular data center environments.

This is not a traditional corporate IT role. We are looking for a technical leader and builder with deep expertise in high‑performance infrastructure environments who is comfortable working directly with customers, engineering teams, deployment teams, and vendors to build scalable, resilient, and high‑density infrastructure platforms.

The ideal candidate will bring strong experience across enterprise and hyperscale networking environments with deep expertise in technologies and platforms from companies such as Cisco Systems, Arista Networks, and Juniper Networks.

This individual will serve as a key technical leader in designing and scaling high‑performance networking infrastructure supporting AI compute environments, liquid cooling deployments, modular data center platforms, and mission‑critical infrastructure globally.

The successful candidate will combine technical leadership with hands‑on engineering and operational engagement—someone equally comfortable in customer discussions, architecture reviews, troubleshooting sessions, and infrastructure deployment environments.

• Drive the development and execution of infrastructure and networking strategies supporting hyperscale, AI, cloud, and modular infrastructure deployments.
• Lead the design and standardization of scalable, high‑performance networking architectures across global deployments.
• Help establish infrastructure standards, operational procedures, resiliency models, and deployment frameworks.
• Partner closely with Engineering, Product, Manufacturing, and Project Delivery teams to support scalable infrastructure deployment.
• Contribute to operational processes and technical governance models that enable growth, reliability, and agility.
• Serve as a senior technical resource supporting customer engagements, architecture discussions, and strategic infrastructure initiatives.

• Lead architecture and deployment of enterprise and hyperscale networking environments leveraging technologies from Cisco, Arista, Juniper, and related infrastructure vendors.
• Design high‑bandwidth, low‑latency network architectures supporting AI workloads, GPU clusters, storage systems, and mission‑critical applications. Support Layer 2/Layer 3 networking, EVPN/VXLAN, spine‑leaf architectures, BGP, routing protocols, and large‑scale switching environments.
• Drive network resiliency, redundancy, scalability, and operational performance improvements.
• Partner with infrastructure and compute teams to support integrated AI infrastructure solutions.
• Evaluate emerging technologies and recommend future‑state networking architectures aligned with business needs.

• Lead infrastructure deployment activities across modular data center and mission‑critical infrastructure environments.
• Support commissioning, testing, validation, and operational readiness processes.
• Establish and maintain standards for infrastructure lifecycle management, monitoring, reliability, and supportability.
• Partner with field operations and project delivery teams to resolve infrastructure and deployment challenges.
• Support customer escalations and critical operational troubleshooting activities when required.

• Develop strong working relationships with networking, compute, storage, and infrastructure vendors.
• Participate in technical evaluations, vendor selection processes, and…
