Role Overview The Whitespace Specialist is a hands‑on data center professional who supports everything from the raised floor to the top of the rack in GPU data halls. Working on a Crystal Equation team under the Team Lead, the Specialist turns the client’s design standards into rack layouts, power and cooling plans, and cabling designs for client approval. They then oversee installation by the client’s contractors, verify the work, keep records accurate, and provide ongoing support through changes, troubleshooting, and continuous improvement.
Responsibilities
- Design and capacity planning: Prepare rack and row layouts, rack elevations, and floor plans for high-density GPU deployments; calculate per‑rack and per‑row power and cooling budgets; support capacity planning for upcoming GPU generations; and review vendor and integrator drawings to identify conflicts before installation.
- Power distribution: Specify overhead busway, tap‑offs, and rack PDUs; verify A/B redundancy and phase balancing; and validate actual rack load against design during deployment.
- Liquid and air cooling: Support deployment and commissioning of direct‑to‑chip liquid cooling, CDUs, manifolds, quick disconnects, and rear‑door heat exchangers; plan containment and airflow for air‑cooled and hybrid rows; and coordinate with Facilities on leak detection, coolant quality, and thermal monitoring.
- Structured cabling: Design fiber and copper cabling for InfiniBand, RoCE, and Ethernet fabrics; oversee installation against cabling standard; and perform or witness certification and optical testing, with documented results.
- Deployment and commissioning: Coordinate receiving, rack‑and‑stack, cabling, and power‑on; and execute assigned commissioning checklists for power, cooling, and cabling before handover.
- Operations support: Respond to physical‑layer incidents (failed links, PDU faults, cooling alarms, hot spots), find root causes, track recurring issues, and recommend improvements to standards.
- Documentation: Keep DCIM and NetBox records current for racks, devices, power feeds, and cable connections; and prepare as‑built records, test results, and commissioning sign‑off packages.
- Contractor oversight: Direct contractors and integrators on the floor and hold them to the written standard, escalating issues through the Team Lead.
- Safety and compliance: Follow site safety, security, change management, and AI‑use policies, including verifying all AI‑assisted work against the floor and source systems before it is used.
Requirements
- Five or more years in data center engineering, critical infrastructure, or deployment roles, with hands‑on responsibility for data hall white space.
- Experience designing and deploying high‑density racks (30 kW and up), ideally GPU or HPC.
- Working knowledge of rack power distribution, liquid cooling in production, and containment and airflow management.
- Strong structured cabling expertise, including single‑mode and multimode fiber, MPO/MTP trunks, and optical testing and certification.
- Fluency with rack elevations, floor plans, one‑line and cooling diagrams, AutoCAD or Visio, and DCIM or NetBox.
- Experience directing contractors and integrators on the floor and holding them to a written standard.
- Thoughtful use of AI tools, with every output verified against the floor and source systems.
- Ability to work on site in an active data center, including lifting, standing, and working on ladders, and willingness to travel as described above.
- Authorization to work in the United States, and successful completion of pre‑assignment screening, including background checks.
- Nice to Have Experience with NVIDIA HGX or rack‑scale GPU deployments at a hyperscaler, GPU cloud, or colocation provider.
- Certifications such as BICSI RCDD or Installer, CDCP, or fiber‑testing certifications (for example, CFOT).
- Familiarity with TIA‑942, ASHRAE thermal guidelines, and NFPA 70 / NEC as they apply to the white space.
