Senior Infrastructure Platform Engineer

About the Role We are seeking a hands-on Infrastructure Engineer to focus primarily on capacity and demand planning across data centers and public cloud. You will combine practical infrastructure experience with analytical thinking and strong internal customer relationships to translate future demand into clear capacity models, options, and timely decisions. This is a hands-on planning role grounded in how production infrastructure actually performs. You will proactively engage engineering, application, product, and business teams, and help drive capacity and cost discussions with our existing FinOps engineers. Leadership owns approved forecasts, procurement and investment recommendations and decisions, and team backlog priorities. You provide the evidence, facilitate the planning cadence, and surface issues early. What You’ll Do Build trusted relationships and proactive demand intake with internal customers, connecting delivery plans, workload changes, and business growth to infrastructure needs. Develop headroom, runway, growth, and scenario models for data center and public cloud capacity, documenting assumptions, uncertainty, dependencies, and changes in demand. Validate sizing against production evidence, peak demand, failover conditions, and performance requirements, rather than treating average utilization as sufficient. Account for hardware lifecycle and procurement lead times, cloud quotas, regional availability, and provisioning constraints when developing timing and capacity options. Run a leadership-sponsored planning cadence, maintain clear analytical inputs, and escalate approved threshold crossings for review. Thresholds trigger discussion, not automatic purchases. Help drive FinOps discussions with existing FinOps engineers: facilitate consumption, demand, capacity, and cost conversations; support consumption and spend forecast scenarios; and follow up with agreed action owners without controlling their backlogs. Partner on rightsizing, reclamation, total cost of ownership, workload placement, and commitment analysis. Validate potential savings against resilience and performance needs; FinOps specialists retain ownership of their practice and program. Requirements Five or more years of practical infrastructure engineering or operations experience, with the technical depth and independent judgment expected of a senior engineer. We welcome candidates whose experience has been built in infrastructure operations. Strong communication and collaboration skills across technical and business teams in a global environment. A minimum of four hours of daily overlap with the US Eastern business day is required. Technical Requirements Practical understanding of virtualization, compute, operating systems, storage capacity and performance (IOPS, latency, and throughput), networks, and resilience. Experience with platforms such as VMware or Nutanix and Windows or Linux is relevant; specific vendors are not required.
