Senior Software Engineer, Model Serving

Databricks Databricks · Data AI · Mountain View, CA · Engineering

Databricks is seeking a Senior Software Engineer to join their Model Serving product team. This role focuses on designing and building scalable, low-latency inference systems for AI/ML models (traditional ML to LLMs) on CPU and GPU. Responsibilities include optimizing performance, throughput, autoscaling, and operational efficiency, as well as contributing to core serving infrastructure components like routing, caching, and observability. The role requires strong experience in large-scale distributed systems and model serving infrastructure.

What you'd actually do

  1. Design and implement core systems and APIs that power Databricks Model Serving, ensuring scalability, reliability, and operational excellence.
  2. Drive architectural decisions and trade-offs to optimize performance, throughput, autoscaling, and operational efficiency for CPU and GPU serving workloads.
  3. Contribute directly to key components across the serving infrastructure — from model container builds and deployment workflows to runtime systems like routing, caching, observability, and intelligent autoscaling — ensuring smooth and efficient operations at scale.
  4. Lead technical initiatives that improve latency, availability, and cost-effectiveness across both customer-facing and foundational serving layers.
  5. Establish best practices for code quality, testing, and operational readiness, and mentor other engineers through design reviews and technical guidance.

Skills

Required

  • 5+ years of experience building and operating large-scale distributed systems.
  • Experience in model serving, inference systems, or related infrastructure (e.g., routing, scheduling, autoscaling, and observability).
  • Strong foundation in algorithms, data structures, and system design as applied to large-scale, low-latency serving systems.
  • Proven ability to deliver technically complex, high-impact initiatives that create measurable customer or business value.
  • Experience building architecture for large-scale, performance-sensitive CPU/GPU inference systems.
  • Strong communication skills and ability to collaborate across teams in fast-moving environments.
  • Customer-focused mindset with the ability to align implementation details with product goals.
