Job summary

Tavily in New York seeks a Senior Software Engineer to design and build the billing platform behind a novel search engine tailored for agentic AI consumption.

Responsibilities

• Build reconciliation, idempotency, and invoice-accuracy safeguards to ensure revenue data is always correct.
