About the Role

Join our dynamic Infrastructure Platform team and help us drive a critical initiative to ensure our modernized Kubernetes workflows and large-scale data systems are as cost-effective as they are powerful. This role requires deep expertise in backend software engineering, cloud financial modeling, containerized compute architecture, and object storage paradigms.

Responsibilities

  • Lead the programmatic effort of managing, forecasting, and radically reducing cloud spend.
  • Drive compute cost strategy during migration to Kubernetes.
  • Architect the transition of massive data footprint from AWS S3 to highly efficient alternative storage providers.
  • Architect and execute the large-scale, high-throughput migration of petabytes of data from AWS S3 to lower-cost alternative storage providers.
  • Design, develop, and maintain robust, centralized client libraries (SDKs) to abstract the underlying storage infrastructure.
  • Partner closely with platform engineers to ensure reference architectures for moving legacy workloads to target EKS clusters are cost-optimized.
  • Benchmark migrated services, right-size resource requests/limits, and develop strategies for Reserved Instances (RIs), Savings Plans, and Spot Instance utilization.
  • Develop, maintain, and refine sophisticated programmatic cloud capacity and spend models.
  • Forecast future infrastructure costs based on Kubernetes migration roadmap, storage migrations, and traffic patterns.
  • Write custom software, automation scripts, and Kubernetes operators (using Python, Go, etc.) to enforce automated cost-control guardrails, resource tagging, and intelligent scale-down/cleanup for non-production environments.
  • Manage guardrails via Infrastructure as Code (Terraform).
  • Implement and manage advanced cost observability telemetry.
  • Build transparent, granular chargeback reporting into internal developer platforms.

Requirements

  • 8+ years of Software Engineering or Platform Engineering experience.
  • Proven track record of writing clean, scalable, and maintainable code in Python, Go, or Java.
  • Deep, hands-on experience with object storage APIs (AWS S3, Backblaze) and designing large-scale data transfer pipelines.
  • Proven experience building centralized client libraries, SDKs, or developer abstractions.
  • Experience building programmatic financial models, predicting cloud spend, and performing capacity planning for large-scale cloud migrations.
  • Ability to translate complex technical architecture changes into clear budgetary impacts.
  • Expert-level understanding of AWS billing, pricing models, enterprise discount programs, and scaling behaviors.
  • Strong hands-on understanding of Kubernetes (EKS) compute efficiency, alongside legacy services like Lambda and ECS.
  • Strong background using Terraform to deploy infrastructure and automations.
  • Excellent communication and technical leadership skills.
  • Ability to influence technical decisions across engineering, platform, and finance teams.
