Director, Capacity Planning & Engineering

Every day, tens of millions of people come to Roblox to explore, create, play, learn, and connect with friends in 3D immersive digital experiences– all created by our global community of developers and creators.

At Roblox, we’re building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together, from anywhere in the world, and on any device. We’re on a mission to connect a billion people with optimism and civility, and looking for amazing talent to help us get there.

A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone.

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.

What You'll Own

Capacity Planning

• 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

Deployment & Delivery

• 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).

Data Center Automation (Software Engineering)

• 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.

FinOps

• 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.

You Have:

• 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.

You Will

• 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
• Create a culture and practice of production excellence, security, and cost-efficiency
• Hire and develop senior engineers, managers, and leaders

You are:

• Collaborative, low-ego environment where candid feedback is welcomed and acted on.
