About The Position

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 FinOps. 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.

Requirements

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 FinOps function or cloud cost optimization at scale.
Background in hyperscale, colocation, or edge data center environments.
Exposure to liquid cooling infrastructure for high-density compute.

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 FinOps 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.
Own a critical piece of infrastructure for a platform used by hundreds of millions of people worldwide.
Scale the team to support ongoing growth and new product features.
Drive improvements in partnership with other engineering teams across Roblox
