Machine Learning Infrastructure Engineer, Safeguards Research

Anthropic Anthropic · AI Frontier · San Francisco, CA · AI Research & Engineering

Machine Learning Infrastructure Engineer for Safeguards Research at Anthropic. Focuses on building and scaling infrastructure, data pipelines, and tooling for ML research, specifically for detection and mitigation of AI misuse. Owns training, evaluation, and scoring workflows, aiming to improve iteration speed, throughput, cost, and reliability of inference and scoring workloads. Bridges research and production by creating reliable, production-grade jobs from research workflows.

What you'd actually do

  1. Build and scale the infrastructure and data pipelines behind Safeguards machine learning research
  2. Own the training, evaluation, and scoring workflows researchers use, with a focus on cutting the time between an idea and a result
  3. Design tooling and interfaces, including libraries and command line tools, that researchers can use directly without needing to understand the systems underneath
  4. Build correctness and sanity checking into the stack, so results stay trustworthy as models and workloads evolve
  5. Take the highest-value research workflows from experiments to reliable, production-grade jobs
