Roblox is looking for a Director of Capacity Planning & Engineering to lead the team responsible for translating platform demand into physical infrastructure reality - from supply-demand modeling and hardware procurement through data center deployment and Fin Ops. This is a high-impact leadership role at the intersection of infrastructure strategy, operational execution, and software engineering.

You will lead a team of approximately 20 people organized across four functional areas and will be responsible for scaling Roblox's infrastructure footprint as it continues to grow rapidly.

• Translate platform demand forecasts into hardware requirements
• Own the supply-demand matching process end-to-end, working closely with Data Center, Hardware Engineering, and Supply Chain teams
• Build and refine capacity models that give the business confidence in infrastructure availability months ahead

• Oversee hardware lifecycle from procurement through physical installation and software provisioning.
• Partner with platform and data center operations teams to bring new capacity online reliably and on schedule.
• Own delivery execution for major milestones including new data center buildout (Q4).

• Lead a software engineering sub-team that builds and maintains DCIM (Data Center Infrastructure Management) systems.
• Drive automation for rack delivery, decommissioning, and capacity planning tooling.
• Identify opportunities to scale automation coverage as Roblox's 25+ global data centers expand.

• Oversee cloud spend optimization and on-prem vs. cloud allocation decisions.
• Grow and develop the Fin Ops function, which is lean today but increasing in strategic importance as cloud spend scales.
• Partner with Finance to ensure infrastructure spend is visible, justified, and optimized.

• 10+ years of experience in infrastructure, data center operations, or related fields, with at least 3 years in a director-level or senior leadership role.
• Deep expertise in capacity planning and supply-demand analysis for large-scale infrastructure environments.
• Hands-on familiarity with DCIM systems and data center automation — this role is lower in the stack than platform software (not Kubernetes/cloud-native).
• Experience working across supply chain systems, hardware procurement, and deployment execution.
• Proven ability to lead and scale cross-functional teams including software engineers, planners, and operations specialists.
• Strong analytical and communication skills; comfortable translating complex infrastructure decisions for C-suite audiences.
• Familiarity with AI/GPU infrastructure - Roblox is actively building GPU factory capacity aligned with NVIDIA's next-generation hardware roadmap.
• Experience managing a Fin Ops function or cloud cost optimization at scale.
• Background in hyperscale, colocation, or edge data center environments.
• Exposure to liquid cooling infrastructure for…
