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.
What impact you will have:
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.
What you’ll do:
Infrastructure & Networking Leadership
- 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.
Network Architecture & Engineering
- 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.
Infrastructure Deployment & Operations
- 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.
Vendor & Technology Management
- Develop strong working relationships with networking, compute, storage, and infrastructure vendors.
- Participate in technical evaluations, vendor selection processes, and infrastructure standardization initiatives.
- Support procurement and supply chain teams with infrastructure planning, forecasting, and vendor alignment.
- Stay informed on emerging trends across AI infrastructure, networking technologies, and hyperscale architectures.
Technical Mentorship & Collaboration
- Provide technical leadership and mentorship to infrastructure architects, network engineers, and deployment teams.
- Foster a practical, execution-focused engineering culture centered on operational excellence and customer success.
- Lead by example through hands-on participation in architecture reviews, troubleshooting efforts, deployments, and customer discussions.
- Collaborate across teams to ensure successful infrastructure design, deployment, and operation.
Customer & Solution Engagement
- Support customer solution design, technical workshops, and infrastructure strategy discussions.
- Partner with Business Development and Solutions Engineering teams during customer pursuits and technical evaluations.
- Help position Submer as a leader in next-generation AI and modular infrastructure technologies.
- Translate customer requirements into scalable infrastructure solutions aligned with operational and business objectives.
What you’ll need:
- Bachelor's degree in Computer Science, Engineering, Information Technology, or related technical discipline.
- 8+ years of experience in networking, infrastructure engineering, data center infrastructure, or hyperscale environments.
- Deep expertise with enterprise and hyperscale networking platforms including Cisco, Arista, and Juniper technologies.
- Strong experience designing and operating large-scale network architectures and mission-critical infrastructure environments.
- Experience supporting AI infrastructure, GPU networking, cloud infrastructure, hyperscale, colocation, or high-density compute environments.
- Strong understanding of routing, switching, spine-leaf architectures, EVPN/VXLAN, BGP, network security, and infrastructure resiliency.
- Experience working within fast-paced, high-growth, entrepreneurial businesses.
- Strong technical leadership skills combined with a highly hands-on engineering and operational approach.
- Proven ability to build and scale infrastructure solutions, processes, and best practices.
Preferred
- Experience supporting modular data center infrastructure, AI infrastructure, liquid cooling technologies, or edge infrastructure environments.
- Familiarity with GPU networking environments and AI workload optimization.
- Experience supporting hyperscale or cloud infrastructure providers.
- Strong understanding of infrastructure automation, observability, and operational tooling.
- Relevant technical certifications such as CCIE, JNCIE, Arista ACE, or equivalent advanced networking credentials.
- Based in Houston, Texas, or able to maintain a regular presence in Houston.
