About the role

Engineer role focused on designing, building, and maintaining a high-performance distributed object storage system for Modal's serverless platform, with emphasis on caching, peer-to-peer data sharing, durability, and cost at petabyte scale.

Responsibilities

  • Design, build, and maintain the novel, high-performance distributed object storage system underpinning container images, volumes, and checkpoints.
  • Design caching, preloading, and peer-to-peer layers to hide object-store latency and keep public ingress off saturated uplinks.
  • Own durability and cost at petabyte scale, including streaming and batch replication between origins and garbage collection over billions of objects.
  • Work across the stack from local disk/page cache to distributed blob storage and garbage collection; shape future storage.

Qualifications

  • 5+ years of experience writing high-quality production code
  • Experience building high-performance distributed storage or caching systems at a large scale
  • Strong cloud skills with object storage (S3 or similar), CDNs, and their consistency, throughput, and cost characteristics
  • Strong knowledge of low-level operating system foundations (Linux kernel, file systems, page cache, containers)
  • Willingness to participate in on-call rotation and respond to production incidents
