Senior Software Engineer (Agentic Search) - Billing

We are looking for a Senior Software Engineer to design and build the billing platform behind a novel search engine tailored for agentic AI consumption. This role is based in our New York office, hybrid with the NYC team.

Our APIs are used by millions of developers and the AI agents acting on their behalf, all paying based on what they consume. You will own the systems that turn product usage into accurate, trustworthy revenue, supporting flexible billing models—usage-based pricing, subscriptions, prepaid balances with auto top-up, and enterprise contracts. Correctness is non-negotiable: every event must be measured precisely and every invoice must be right to the cent.

In this position, your responsibility will be to:

• Design and operate the billing platform end to end, from usage events to invoices
• Build metering and usage-aggregation pipelines that turn high-volume events into billable amounts
• 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)

Nice to have:

• Led a billing system migration or re-platform with zero revenue loss or downtime
• Built hybrid billing combining usage, subscriptions, and prepaid in one system
• Worked across both a payments layer (Stripe) and a metering / rating layer (Metronome / Orb)
• Billed a developer-facing / API product with pay-as-you-go and API-key metering
• Used Snowflake for usage aggregation and revenue analytics

Why Tavily?

• Full ownership — small team, you own the entire infrastructure, not a slice of it
• Real scaling challenges — bursty scraping workloads, cache invalidation, multi-region, millions of daily requests
• AI-native company — your infra directly powers AI agents used by leading companies in the space.

• Health insurance: 100% company-paid medical, dental, and vision coverage for employees and families.
• 401(k) plan: Up to 4% company match with immediate vesting.
