Platform Engineer, Billing Systems

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 still ship code and work effectively with Product, Growth, GTM, and Finance

Frontend, ML, voice, and experience with our exact vendors are not required.

Logistics

We sponsor H1B, O1, EB1, L1, STEM OPT, and more. We can't guarantee sponsorship for every role, but if we make you an offer we'll make every reasonable effort, with help from our immigration law firm.

We strongly encourage you to apply even if you don't meet every qualification. The strongest candidates we meet rarely do, so don't exclude yourself prematurely. We're rethinking how humans interact with AI, and doing that well demands diversity of perspective and experience.

We're committed to a fair and accessible interview process. If you need any accommodations or adjustments, please let us know.
