• Ensure alignment between infrastructure programs and Nscale’s business, product, and customer needs

Governance & Delivery Oversight

• Establish portfolio governance frameworks, reporting, and decision‑making structures
• Monitor progress across all programs and projects, identifying risks, dependencies, and capacity gaps
• Provide oversight and guidance to Program Managers and cross‑functional teams
• Drive consistent standards for planning, execution, quality, and documentation

Cross‑Functional Leadership

• Partner with engineering, ops, supply chain, and leadership to ensure portfolio feasibility and readiness
• Facilitate executive‑level updates, portfolio health reviews, and prioritization discussions
• Serve as the bridge across technical, operational, and business teams to maintain alignment

Resource & Capacity Management

• Ensure resources (internal teams, contractors, vendors) are allocated effectively across initiatives
• Identify scaling needs and support hiring plans for program, project, and delivery functions
• Optimize deployment cycles and reduce portfolio‑level bottlenecks
• Establish processes and tooling that improve predictability, throughput, and transparency
• Analyze post‑deployment data to drive improvements across deployment quality, timelines, and cost performance
• Build operational maturity across the portfolio through repeatable methodologies and best practices

What You Bring

• 8+ years of experience in portfolio management, technical program management, or infrastructure delivery leadership
• Strong background in datacenter, hardware infrastructure, cloud, or large‑scale technical environments
• Deep understanding of GPU compute, networking, racks, power/cooling, or high‑density datacenter operations
• Ability to influence and lead cross‑functional teams without direct authority
• Exceptional communication skills, including executive reporting and risk storytelling
• Strong analytical mindset with experience driving data‑based decisions
• Comfortable operating in high‑growth, fast‑moving, ambiguous environments.

Nice to Have: Experience with AI/ML workloads, high-performance networking (InfiniBand/RoCE), CMDB or asset systems, capacity planning models, or enterprise GTM collaboration.
