## Job description

## 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.](https://wisprflow.ai/post/the-master-plan)

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.

- [Introducing Wispr Advanced Interfaces Lab](https://wisprflow.ai/post/wispr-labs)
- [Technical challenges behind Flow](https://wisprflow.ai/post/technical-challenges)

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.

## About Wispr Flow

## Company Overview
- **One-liner**: Wispr Flow develops voice-to-text AI technology that lets users dictate content naturally across applications, aiming to replace keyboards with voice for faster, more effortless communication.
- **Entity Type**: Private (Series A – II)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2021
- **Founders**: Not publicly available

## Core Business
- **Primary industry**: AI-powered voice interface / voice dictation
- **Target customers**: B2C (individuals) and B2B (teams, lawyers, accessibility users)
- **Mission**: “Make interacting with your devices as effortless as talking to a close friend” and “create a world where people enjoy more clarity, connection, and agency – with less screen time, context-switching, and cognitive overload.”

## Products & Services
- **[Flow](https://wisprflow.ai/)**: A consumer voice dictation platform that works across Mac, Windows, iPhone, and Android. It transcribes speech 4× faster than typing, includes AI auto-edits (removes filler words, formats text), supports 100+ languages, and learns a personal dictionary. Available as a free 14-day trial.
- **Flow for Teams**: Adds snippet libraries, voice shortcuts, and team‑wide settings.
- **Flow for Lawyers**: Tailored formatting and legal‑specific commands.
- **Flow for Accessibility**: Designed to help users who cannot rely on traditional input methods.

## Market Standing
- **Valuation / Market Cap**: Not disclosed
- **Key Metric**: Total funding raised – **$81.6M** (latest round: Series A – II, raised $25M)
- **Notable Investors**: Notable Capital, Menlo Ventures, Activate, Flight Fund, Peak XV Partners, plus 31 other institutional investors. Individual backers include Rakesh Mathur (CEO, Superhuman), Rahul Vohra (CEO, Superhuman), Fred Ehrsam (Founder, Coinbase), and others.
- **Growth Signals**: “Flow became the first consumer voice dictation platform that makes people want to use voice more than their keyboards.” The product is already available on four platforms, supports 100+ languages, and the company has filed 9 patents (e.g., silent speech interaction systems). Headcount is estimated at over 200 employees [cbinsights.com](https://www.cbinsights.com/company/wispr).

## Competitive Advantages
- Works **across any application** (native on Mac, Windows, iOS, Android) – not locked to a single app.
- **AI auto-edits** turn rambled speech into clean, formatted text without manual correction.
- **4× faster than typing** and supports a personal dictionary that learns unique words.
- Strong **patent portfolio** covering natural language processing, computational linguistics, and silent speech.

## Strategic Focus
- Rethinking the fundamental layer of computing: moving from screen‑first to **voice‑first** interfaces.
- Expanding from dictation into broader voice‑based interaction tools (e.g., silent speech, AI commands).
- Building a platform that is both **useful** (trustworthy) and **ubiquitous** (available everywhere).

## Why Work Here
- **Culture**: Values include “unreasonably ambitious and self‑improving,” “kind and direct,” “truth seeking,” “opinionated about simplicity,” and “tuned into emotion.” The team is described as designers, AI researchers, and engineers who want to “have fun” while building ambitious products.
- **Work environment**: HQ in San Francisco, but **open to remote**. Visa‑friendly and relocation assistance available.
- **Perks**: Health/dental/vision insurance, unlimited PTO (encouraged to take days off), generous parental leave, visa assistance, 401k match, commuter benefits, relocation assistance.
- **Engineering culture**: Focus on first‑principles thinking, simplicity, and delight. “Don’t see a role that fits? Email us your resume” – open to unsolicited applications.
