> Designs whitespace environments for large-scale AI GPU clusters, including rack layouts, power, cooling, and cabling. Reviews contractor designs, ensures compliance with standards, and owns capacity planning. Requires 7+ years in data center infrastructure.

## Job Description

## Responsibilities
- Architect HPC clusters by designing whitespace layouts, including rack placement, aisle configuration, hot/cold aisle containment, equipment density, and airflow strategy for high-density GPU deployments
- Collaborate with electrical and mechanical engineers to integrate power and cooling infrastructure into whitespace environments
- Collaborate with Network Engineering to define and validate physical layer requirements (structured cabling, pathway planning, port density) for high-speed AI cluster interconnects, ensuring design compatibility with both physical and logical network architectures
- Advise Data Center build teams/contractors to ensure data center build out matches design and architecture specifications. Provide direction to optimize performance, scalability and cost-effectiveness
- Develop and maintain **CAD/BIM** drawings, schematics, capacity planning models, and technical documentation to support site design, construction, operations, and audits of data center white space
- Own capacity planning within the white space through modeling that incorporates growth, utilization, and infrastructure scaling
- Validate electrical and mechanical load distribution across whitespace fit-outs, including review of striping plans and upstream load balancing under normal and failover conditions
- Partner with Infrastructure Strategy and Operations by providing design review and technical guidance during the white space fit-out phase
- Drive continuous improvement in design standards, build processes, and quality assurance, including identifying opportunities to improve infrastructure reliability, reduce time-to-rack, and apply new technologies such as liquid cooling and high-density power architectures
- Ensure all designs comply with applicable standards including **TIA-942**, **Uptime Institute Tier** guidelines, **ASHRAE** thermal recommendations, and relevant local codes and safety regulations

## Requirements
- 7+ years of experience in data center design, critical facilities engineering, or infrastructure delivery, with deep technical knowledge across the full stack (power, cooling, network) as it pertains to white space design and implementation
- Demonstrated experience serving as an owner's engineer or resident engineer, including reviewing consultant drawings, managing contractor compliance, and interpreting construction specifications and submittal documents
- Strong working knowledge of how facility electrical (**UPS**, switchgear) and cooling (**CRAC/CRAH**) infrastructures interface with, and support, high-density white space systems (**PDUs**, in-row cooling, **CDUs**, **RPPs**)
- Proficiency with **CAD/BIM** tools such as **AutoCAD**, **Revit**, or equivalent; ability to produce and review technical drawings, schematics, and capacity models
- Working knowledge of industry standards including **TIA-942**, **Uptime Institute Tier** classifications, **ASHRAE** thermal guidelines, and **ANSI/BICSI**; familiarity with local building codes and safety regulations
- Proven ability to manage multiple concurrent projects across different sites and work effectively with **MEP** engineers, general contractors, and equipment vendors in fast-moving environments
- Willingness to travel to data center sites as required for technical due diligence, design inspections, and final white space deployment sign-off

## Nice to Have
- Experience with liquid cooling systems for high-density GPU clusters, including direct liquid cooling (**DLC**), immersion cooling, or rear-door heat exchangers, and familiarity with associated power and plumbing infrastructure
- Background in hyperscale or AI-native infrastructure deployments, including reference architecture validation, and the development of final design acceptance criteria at scale
- Familiarity with **DCIM** platforms, telemetry and monitoring systems, and infrastructure-as-code tooling for capacity and utilization tracking

## Compensation
**US base salary range: $210-250K + equity + benefits.** Salary determined by location, level, role, experience, skills, and job-related knowledge.
