## 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

Our agents already write code and respond to incidents around the clock, but they can't yet tell when they're done, so every loop still ends with a human checking. You'd be the first to build the verification and evaluation layer that lets them finish with confidence.

## What you'll do

- Build end-to-end verification loops that let agents determine when their work is actually complete
- Create fast, reliable testing environments and turn failures and human feedback into durable evaluation signals
- Improve how context, instructions, skills, and memory are delivered to agents—and measure what makes them perform better
- Operate the agent fleet as a production system and measure its quality, adoption, and impact

You may be a fit if

- You've built internal tools that other engineers adopted, and you can explain how you measured their impact
- You use agentic coding tools deeply and have specific opinions about where they succeed and fail
- You've built evaluation or verification infrastructure such as test harnesses, CI systems, eval pipelines, or benchmarks
- You can work hands-on across application code, infrastructure, and unfamiliar systems
- You are empirical about your own work, attentive to subtle failure modes, and comfortable owning ambiguous problems

Prior experience in voice, model training, or our product domains is 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.
