The Role Together AI is building its infrastructure footprint at scale, and this role is central to making that happen. As an Infrastructure Design Engineer, you will own the design, planning, and technical execution of whitespace environments (where servers, storage, and network equipment are deployed) across our AI data center portfolio. You are the in-house expert who ensures that rack layouts, power distribution, cooling strategy, structured cabling, and physical infrastructure design are all built to support the density, redundancy, network and reliability
requirements of large-scale AI GPU clusters. You will serve as the lead engineer across our DC portfolio, creating white space designs, reviewing partner and contractor designs, and ensuring plans are executed to spec. You will work closely with the Infrastructure Strategy, Infrastructure Engineering, and Operations teams, as well as external MEP consultants, general contractors, and data center partners. This is a technical role on a small, high-accountability team where your judgment directly shapes our ability to bring capacity online on time and to spec.
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.
