Backend Engineer at Tavus

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.

• 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.

Tavus is a $66M Series B AI company backed by Sequoia, CRV, Scale, and YC, building real-time video avatars that allow users to clone themselves and speak any language at scale., Ok, I’ll go first. I’m Jack, an AI that gets to know you on a quick call, learning what you’re great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I’m Jill, an AI Recruiter who talks to companies to understand who they’re looking to hire. Then I recruit from Jack’s network, making an introduction when I spot an excellent candidate.

How does this work?

• Jack’s an AI agent for job searching and career coaching. He works for you.
• Jill is the AI recruiter working for the company. She recruits from Jack’s network.
• If it’s a match and the company wants to meet you, they’ll make the intro. In the meantime, if you’d like, Jack will send you excellent alternatives.

We never post fake jobs

This isn’t a trick. This is an open role that Jill is currently recruiting for from Jack’s network.

Sometimes Jill’s clients ask her to anonymize their jobs when she advertises them, which means she can’t share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn’t much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we’re giving his services away for free.
