From the employer
About Wispr
Wispr is an AI research and product company building the voice interface for computing. AI can now reason, code, and act. Yet, humans still do the work of the interface. We think that’s backwards.
Our first products are Flow, which lets you speak naturally in any application, and Notetaker, which builds context across conversations. We’re building toward an interface that can perceive, understand, and take action with earned trust. That means solving hard problems across models, systems, and product - and caring about the final human experience as deeply as the technology underneath it.
We’re a talent-dense team that holds strong opinions, tests them quickly, and builds technology that sparks joy. Our goal is to build the first voice interface used every day by a billion people.
About the role
Wispr serves consumers, teams, and enterprises with varying subscriptions, usage limits, seats, bundles, currencies, and payment methods. You’ll own the platform beneath every pricing motion, from its core abstractions to its vendor integrations. You’ll make it possible to launch new products and pricing quickly without creating operational complexity or risking customer trust.
What you’ll do
Own the billing platform across consumer and enterprise motions
Reconcile state across Stripe, RevenueCat, Sequence, IAP, and future vendors
Build abstractions that support new SKUs, bundles, currencies, usage models, and entitlements
Handle the operational realities of proration, credits, true-ups, dunning, and invoicing
Create testing and observability that catch divergence before customers do
You may be a fit if
You’ve built billing systems across both consumer and enterprise motions
You’ve migrated live pricing or billing systems without customer or revenue impact
You’ve made architecture decisions in this domain and lived with their consequences
You know where billing demands rigor and where the system can remain flexible
You work effectively with Product, Growth, GTM, and Finance
Frontend, ML, voice, and experience with our exact vendors are not required.
