Supports treasury operations for debt, leases, derivatives, hedges, letters of credit, banking relationships, structured financing, intercompany funding, and cash forecasting. Prepares covenant compliance reports, debt forecasts, regulatory documentation, transaction reporting, and leadership materials. Coordinates with lenders, banks, hedge counterparties, counsel, and internal accounting teams while maintaining accurate recurring deliverables and counterparty records.

Own mechanical design standards and cooling architectures for large-scale AI data centers. Design central plants, hydronic distribution, air-cooling, and liquid-cooling systems; perform thermal and hydraulic calculations; select and size equipment; review designs and vendor submittals; coordinate with engineering, construction, commissioning, and operations teams; support procurement, testing, commissioning, and failure investigations. The role requires frequent cross-functional collaboration and travel to project sites, manufacturers, and partner facilities as needed.

Architects scalable compute platforms for AI/ML, simulation, and high-throughput workloads. Defines infrastructure standards, reference designs, roadmaps, and technical requirements across hardware and software. Evaluates CPU, GPU, and accelerator technologies while balancing performance, density, power, cooling, and cost. Leads platform validation and performance characterization, collaborates across product and engineering teams, and mentors systems engineers. Requires expertise in large-scale GPU/HPC or cloud platforms, interconnects, performance tuning, scheduling, orchestration, and compute lifecycle management.

Architect high-performance, low-latency networking for large-scale GPU clusters, storage systems, cloud platforms, and multi-tenant environments. Define network topologies, standards, reference designs, and scalability roadmaps; evaluate advanced InfiniBand and Ethernet technologies; optimize routing, congestion control, optical connectivity, automation, telemetry, resiliency, and fault tolerance. Partner with compute and storage architects, guide technical strategy, and mentor engineering teams.

Own mechanical controls standards and automation architectures for large-scale AI data centers. Develop sequences, control narratives, points lists, alarm matrices, and controller requirements for cooling and heat-rejection systems. Review designs, coordinate cross-functional controls requirements, support testing and commissioning, troubleshoot control issues, and improve standards using operational lessons. The role requires expertise in PLC, DDC, BMS, instrumentation, control loops, industrial communications, and mechanical cooling systems, with travel to project and partner sites as needed.

Own electrical design standards and reference architectures for low-voltage power systems supporting high-density AI data centers. Lead designs from transformer secondary through rack-level distribution, perform electrical studies, develop technical documentation, evaluate designs, coordinate with facilities and engineering teams, and support equipment selection, testing, construction, commissioning, and failure investigations. The role requires office presence in San Francisco or San Jose four days per week and travel to project sites and partner facilities as needed.
