Platform Engineer, Billing Systems
ABOUT WISPR
We're building the first voice interface a billion people use every day.
Our first product, Flow, lets you talk instead of type anywhere on your computer or phone, and turns messy speech into polished text that is ready to send. It's scaled from $2M → $50M in ARR in under 12 months with millions of users and thousands of enterprise customers. How we think → https://wisprflow.ai/post/the-master-plan

ABOUT THE ROLE
Most billing engineers spend their careers on one motion. Ours runs four at once.
Consumer, with multiple tiers. B2B, with seat-based pricing, usage-based pricing, and enterprises that want both at once, split across cost centers. International pricing in over 30 currencies and 50 payment methods, because someone in São Paulo shouldn't have to think about how they pay. And a growing set of products that customers can bundle however they like.
Underneath that, we reconcile billing state across RevenueCat, Stripe, Sequence and more.
Why this is hard: we ship new products and SKUs every month, and none of that is allowed to cost us a single failed charge or a customer seeing the wrong number. Fast iteration and near-perfect reliability usually pull against each other. It’s hard to balance both together, and it's why this role needs someone who has experienced the pain before rather than someone learning on the way through.
You'd work with the platform team, product engineers, the GTM team, the data & analytics team and the CEO, Tanay, who's been one of the key stakeholders on this system since the beginning.
WHAT YOU'LL DO
- Own billing end to end, across consumer, B2B, and everything we bundle next.
- Allow us to ship new SKUs and pricing experiments in days.
- Keep billing state reconciled across RevenueCat, Stripe, Sequence and whatever comes after.
- Build the enterprise side out: seats, usage, cost centers, and the flexibility to...
