AI Model Serving Cold Start Latency Engineer

David Dubois

Full-time · Job · Los_Angeles

About the role

We just closed our Series B and are scaling fast. We need a senior infrastructure engineer to solve one of our most persistent customer complaints: cold start latency when spinning up new model containers. Every extra second of cold start time shows up directly in customer SLAs, and our current warm-pool approach doesn't scale cost-effectively. You'll redesign how we pre-warm and schedule model containers across multi-cloud GPU capacity, working with our platform team on both the scheduling logic and the cost tradeoffs.

Responsibilities

  • Redesign container pre-warming strategy to reduce model serving cold start latency
  • Build scheduling logic that balances latency targets against GPU cost
  • Benchmark cold start performance across AWS and GCP GPU instance types
  • Partner with customer-facing teams to align latency targets with SLAs

Requirements

  • 5+ years of experience with Kubernetes-based infrastructure at scale
  • Deep understanding of container scheduling and GPU resource management
  • Experience with multi-cloud deployments across AWS and GCP
  • Track record of reducing latency in production ML serving systems

Benefits

  • Fully remote position
  • Meaningful equity post-Series B
  • Health, dental, and vision coverage
  • Annual infrastructure conference budget
  • 401k matching
