-
Debug production incidents, identify root causes, and implement durable fixes.
-
Synchronize and index terabytes of client data while managing fine-grained permissions.
-
Operate and optimize systems that process millions of LLM calls per month with high reliability.

Ability to own features completely — from design decisions through debugging live production issues.
Nice to have:
-
Experience with Python, tRPC, or similar backend technologies.
-
Familiarity with GenAI platforms or LLM integrations (e.g. OpenAI, Anthropic, or similar).
-
Experience mentoring junior engineers or leading technical code reviews.
-
Comfort working in a fast-paced, high-growth product environment.
