## 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

We’re looking for a Lead Software Development Engineer in Test (SDET) to build the quality practice behind Flow. You’ll own test strategy, write automation, and personally investigate the product while helping our QA team grow.

## What you'll do

- Build reliable automation. Develop and maintain automated tests for critical journeys across desktop, mobile, backend services, and integrations. Choose the right mix of unit, integration, and end-to-end coverage.
- Make regression testing continuous. Partner with engineering to run automated checks against internal builds, integrate them into CI/CD, and establish dependable release gates.
- Test beyond the happy path. Personally explore real-world voice workflows, permissions, device and network changes, cross-app behavior, and updates. Catch usability and consistency issues as well as functional bugs.
- Own release confidence. Prioritize testing by risk, investigate failures, and use test results, telemetry, and customer impact to make clear release recommendations.
- Bring quality into development. Work with engineering, product, design, and support from planning through launch. Turn requirements, incidents, and escaped defects into better coverage.
- Lead through doing. Set standards, coach our QA team and testing partners, and coordinate coverage while remaining hands-on and driving testing yourself.

## Who you are

- An experienced quality engineer. You’ve owned testing for complex software and built or maintained automated suites that teams rely on.
- A capable programmer. You can write readable test code, build fixtures and test harnesses, debug failures, and keep automation reliable in CI.
- A systems thinker. You reason across clients, APIs, operating systems, and integrations. You know where mocks help and where real devices and end-to-end checks are essential.
- An incisive investigator. You turn vague reports into reproducible bugs, use logs and other evidence to isolate causes, and distinguish product failures from test or environment failures.
- Product-minded and detail-oriented. You care about usability, responsiveness, accessibility, and trust, and know which risks matter most to users.
- A hands-on leader. You communicate clearly, coach others, and build useful processes in a fast-moving team. Experience with native apps, audio, speech recognition, or AI output evaluation is a plus.

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.
