Our deal

Open Whisper Systems is making private communication simple. We design open protocols, develop Open Source software, and give it away for free.

It's challenging work, and we pay ourselves to take it on, but we're not a business. We started this project because we think making things is fun, privacy is valuable, and cryptography is remarkable.

Working at Open Whisper Systems is an opportunity to collaborate with passionate people in an environment where it's possible to be creative and effective.


Not VC Funded

We're not a business. We'd rather think creatively than think about the dough.

Small Team

We like working closely with a few people to build something great. We're passionate, but not wingnuts.

Open Salaries

We have an open process for determining how much everyone is paid.

Open Source

Everything we produce is open source. Every time we write code, we get to share it with the world.

Not really benefits


No gym membership, but any time you feel like doing push-ups, we'll do them with you.


No catered meals, but sometimes we cook together. And if you lose a bet, it probably means a sushi dinner is on you.


Most of us use our own laptops, but we've got your surfboard covered.

We're looking for

  • iOS Developer. Someone intimately familiar with iOS development and internals, who has an appreciation for the craft of software development and experience with making decisions that result in great products. No experience with cryptography necessary, just solid experience developing for iOS and an eye for good design.

  • Android Developer. Is the pleasure center of your brain directly wired to the experience of a slick UX or a nice animation? Do you hunt down memory leaks and StrictMode violations for fun? We're looking for someone with deep knowledge of the Android framework and an equally strong intuition for pairing beautiful app experiences with beautiful code. You'll be the architect of major features, making your code available to the world. You don't need to be a security expert; it's knowing how to make complicated systems simple to use that's at the heart of what we do.

  • Mobile UI / Product Designer. We’re seeking an original thinker with strong visual design skills ready to help make private communication simple. You'll take on developing the look and feel of Signal on iOS, Android, and the desktop. People all around the world — from activists in Egypt to journalists in Europe to teenagers in Brazil — depend on Signal to keep their communication private. You’ll be responsible for updating the visual design for the app and helping shape consistent guidelines to communicate a compelling user story across our products and other touchpoints. You’ll work closely with a team of engineers with a passion for making usable software. No experience with cryptography necessary, just intuition for what makes a great product and solid experience designing products that are a joy to use. If you believe making things is fun, privacy is valuable, and cryptography is remarkable - lets talk.
