Job Description

At Weights Biases, our mission is to build the best developer tools for machine learning. Weights Biases is a series C company with $250 million in funding and a rapidly growing user base. Our platform is an essential piece of the daily work for machine learning engineers, from academic research institutions like FAIR and UC Berkeley to massive enterprise teams including iRobot, OpenAI, Toyota Research Institute, Samsung, NVIDIA, Salesforce, Blue Cross Blue Shield, Lyft, and more.

As a Performance Engineer you will work closely with the Infrastructure Team to scale wandb.ai in lockstep with our exponentially growing userbase. You’ll be instrumental in the evolution of our platform as we grow to ingest and query petabytes of data, and guide technical decisions and architectural choices to maximize performance.

  • Define the architecture for our next-generation data ingestion and querying systems to achieve high performance and reliability.
  • Advise and educate development teams on how to build and operate scalable, performant services.


  • 5+ years of experience managing, monitoring, and debugging distributed systems/databases (MySQL, Postgres, BigTable, Kafka, etc.) in production.
  • Advanced knowledge of at least one cloud provider (AWS, GCP, Azure).
  • Strong grasp of at least one higher-level language and its ecosystem (Go, Python, TypeScript, etc.)
  • A willingness to dive into and debug issues at any layer of the tech stack, from the application layer to the network.
  • A demonstrated ability to think critically under pressure.
  • Excellent communication skills and an ability to explain deeply technical concepts simply.

Why join us?

  • Top-tier machine learning teams rely on our tools for their daily work at companies including OpenAI, Toyota Research Institute, Lyft, Samsung, and Pandora.

  • Our experienced founding team has successfully built and sold ML tools in the past at Figure Eight, and their deep knowledge of our industry, empathy for our users, and skillful management is driving WB to success.
  • Customers genuinely benefit from our tool. Here's a quote from Wojciech Zaremba, Cofounder and Robotics Lead, OpenAI: "WB allows to scale up insights from a single researcher to the entire team, and from a single machine to hundreds of them."
