Customer Engineer

Modal Modal · Data AI · New York, NY · Engineering

Customer Engineer role focused on AI/ML infrastructure, working directly with customers to debug and optimize workloads, while also shipping fixes, features, and automation to improve the core platform. Requires depth in either low-level infrastructure or ML/AI.

What you'd actually do

  1. Ship code that matters. Fix bugs, build features, and create automation that improves the experience for every Modal user — not just the one who reported the issue.
  2. Work directly with customers. Help developers and ML engineers debug, optimize, and architect their workloads across Slack, email, and calls.
  3. Build scalable systems. Design tooling, dashboards, and automated workflows that make support efficient at scale — delighting customers at the most important moments.
  4. Close the feedback loop. Translate patterns you see in the field into concrete improvements — docs fixes, API changes, or new feature proposals.
  5. Contribute to open source and technical content. Write examples, build demos, and publish content that helps the broader community succeed on Modal.
