NScale is a GPU cloud provider engineered for AI, offering high-performance infrastructure for AI-focused companies. The role involves leading mechanical design and engineering governance for data centers, ensuring optimal cooling and infrastructure for AI deployments.
Responsibilities:
- Lead concept, schematic, and detailed design reviews for new builds and expansions
- Establish and maintain design standards and reference architectures to enable repeatable, rapid deployment across the U.S
- Ensure designs meet availability, maintainability, and efficiency targets, and are suitable for high-density AI workloads
- Provide engineering support through LLE Equipment procurement, submittals, RFIs, field changes, and issue resolution during construction
- Vendor and consultant leadership: Select and manage architectural & engineering consultants throughout design process from schematic to construction documents. Enforce quality and documentation standards through document issuance reviews
- Lead review of internal and external third-party CFD studies to validate airflow management, temperature compliance, and thermal resilience throughout the site, both inside and outside of the facility
- Partner cross-functionally with construction, commissioning, operations, procurement, and product/platform stakeholders to ensure mechanical systems meet business and customer requirements
- Continuous improvement: Implement lessons learned from deployments, improve reliability and maintainability, and push innovation in cooling and energy efficiency
- Partner cross-functionally with construction, commissioning, operations, procurement, and product/platform stakeholders to ensure mechanical systems meet business and customer requirements
- Build and lead a high-performing team of engineers including hiring, mentoring, performance management, and career development
- Support mechanical technical due diligence for potential colocation sites, including assessment of cooling architecture, redundancy, capacity headroom, maintainability, and operational maturity
- Review and validate landlord/operator-provided documentation, including basis of design, one-lines/P&IDs (where available), sequences of operation, maintenance records, incident history, and commissioning reports
- Define and negotiate mechanical lease exhibits and technical schedules (capacity commitments, metering approach, operating envelopes, maintenance windows, response SLAs, and change control requirements)
- Evaluate fit for high-density AI workloads, including constraints on inlet temperatures, liquid cooling readiness (if applicable), heat rejection limitations, and expansion pathways
- Support early-stage site screening by defining mechanical utility and constructability requirements (cooling approach, water strategy, heat rejection constraints, climate considerations, expansion capacity)
- Lead mechanical due diligence for greenfield and brownfield acquisitions, including evaluation of existing infrastructure condition, remaining useful life, maintainability, and upgrade pathways
- Assess site constraints and risks that impact mechanical design and delivery including heat rejection feasibility (air-cooled vs evaporative vs hybrid) and Space planning for plant rooms, yards, and equipment setbacks
Requirements:
- Bachelor's degree in Mechanical Engineering
- Professional Engineering License
- 5+ years of mechanical engineering experience in mission-critical facilities, with significant time in data center design
- 3+ years in engineering leadership (people leadership and/or leading large multi-site programs)
- Strong understanding of Cooling systems for high-density compute (air and liquid-cooled strategies, heat rejection options, redundancy models) as well as hydronic systems, piping design, equipment selection, and controls sequences
- Experience working with U.S. engineering firms, AHJs, and code environments (state/local variations)
- Strong presence and decision-making capability
- Pragmatic, risk-based leadership style suited to fast-paced construction environments
- High judgment in high-consequence scenarios
- Ability to challenge delivery teams while maintaining partnership
