Job Description

Tavily is seeking a Senior Software Engineer to design and operate its billing platform that underpins a novel agentic search experience.

The role offers a yearly salary range of USD 147,200 to 224,300.

  • Design and operate prepaid credit/wallet systems with auto top-up and balance management
  • Support enterprise/contract billing with custom pricing, negotiated terms, and scheduled invoicing
  • Build reconciliation, idempotency, and invoice-accuracy safeguards to ensure revenue data is always correct
  • Lead the migration to the next generation of our billing system with no revenue loss or downtime
  • Define observability and quality metrics for billing correctness, freshness, and throughput
  • Ensure billing systems meet audit and compliance requirements (SOX, financial audit)

Requirements

  • 6+ years building production backend systems, of which 3+ years actively building and operating billing or metering systems in production
  • Hands-on experience with usage-based / metered billing: rating, aggregation, and proration logic
  • Hands-on experience with subscription / recurring billing alongside usage-based models
  • Hands-on experience with prepaid credits / wallet systems and auto top-up mechanics
  • Hands-on experience with enterprise / contract billing: custom pricing and negotiated terms
  • End-to-end integration of a third-party billing platform (Stripe Billing, Metronome, Orb, or Zuora)
  • Strong expertise in Python and TypeScript/Node (Go a plus)
  • Production experience with transactional databases (Postgres or equivalent) for financial-grade data
  • Built high-volume event / usage pipelines into a data warehouse (Kafka or Kinesis Snowflake or BigQuery)
  • Owned billing correctness in production: reconciliation, idempotency, invoice accuracy
  • Product-Led Growth (PLG) experience: worked on billing for high-volume, self-serve users
  • Hands-on with Auth0, Okta, or similar identity systems in production
  • Shipped revenue systems under SOX or financial audit constraints
