# Backend Engineer at Tavus

- **Company:** Jack & Jill, Inc.
- **Location:** San Francisco, CA, United States (Remote available)
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Distributed Systems, Amazon DynamoDB, TypeScript, Backend, AI Platforms, Stripe, AWS Data Analytics, NestJS
- **Published:** July 16, 2026
- **Apply:** https://arc.dev/remote-jobs/j/redirect/p51oveiqju

## About the Role

* Proven experience building or owning usage-based billing systems, ideally with deep expertise in Stripe and exposure to Orb or Apple IAP.
 * Strong proficiency in TypeScript and NestJS for backend services, with the ability to manage AWS data plumbing including Lambda, DynamoDB, and CDK.
 * Deep understanding of distributed systems principles, including event durability, reconciliation, and exactly-once processing, specifically within a payments or fintech context.

## Description

You will own the end-to-end revenue plumbing for Tavus's AI platform, managing usage-based billing across Stripe, Orb, and Apple IAP. This high-autonomy role involves building Pricing V2, automation for coupons and credits, and scaling distributed systems to ensure event durability and idempotency as the company expands globally into new markets., * Own the mission-critical revenue domain at a fast-growing, ~40-person startup where AI is the core product, not just a marketing hook.

 * Join a well-funded Series B company backed by top-tier investors like Sequoia and CRV, offering the stability of capital with the impact of an early team.
 * Solve complex distributed-systems challenges where "close enough" isn't an option, moving from manual workarounds to sophisticated, automated billing infrastructure at scale.

What You Will Do

 * Architect and lead the transition to "Pricing V2," implementing usage-metering pipelines, concurrency holds, and automated provisioning for enterprise clients.
 * Build robust infrastructure for coupon and credit lifecycles, enabling the growth team to launch self-serve promotions without direct engineering intervention.
 * Ensure financial correctness across parallel payment providers (Orb, Stripe, Apple IAP) by developing idempotent webhook processing and reconciliation pipelines to prevent revenue loss.
