Making a good app is easy. To make a truly great app, we have to push the boundaries set by mobile frameworks. We go out of our way to make our mobile clients fast, secure and beautiful.

Your challenge: build technology, tools and product for mobile that delights users. Implement on-the-fly encryption so fast, no one notices what effort we go through behind the scenes. Pay attention to detail so users immediately get that this is a five star product.


  • Mobile client implementation
  • Mobile encryption
  • Sync algorithms
  • Iterate to perfect speed and user experience
  • Expand mobile developer toolset


To build great products, make what people want.

Your challenge:  without breaching any privacy, measure where we can improve and how. Are we delivering value? What type of usage and user do we deliver the most value to?

We determine product sucess by usage and iterate based on data insight. Build the infrastructure that enables us to see more and make better decisions.


  • Data capture
  • Analytics infrastructure
  • Insight generation
  • Product development


Being in control is hard and complicated for normal human beings. We solve hard technology problems to make their lives easier.

Your challenge: build the infrastructure to bring privacy and security technology to non-expert consumers. The secure cloud platform we are building is only the start. We are creating tools to enable fast product iterations, and inventing ways to prevent copying. We are creating file formats that make perfect copies impossible. Join us to build the platform for the privacy needs of everyday life.


  • Cloud backend and storage
  • Scaling to support a global cloud of mobile endpoints
  • Fast mobile sync protocols
  • Security engineering & cryptography


In a digital world, the meaning of privacy changes. How does a new generation manage their personal space? What does an intuitive solution look like and how does it differ based on content and context? What visuals work best in a privacy workflow?

Your challenge: think ahead and define what KeepSafe's future product solutions look like. Own product design top to bottom from research to prototyping to UX and UI.


  • User research
  • Product research
  • User experience
  • User interface design

KeepSafe is taking off and you can help shape our success by joining our close-knit team. We want to hire people who want to build a great product and also define and build our culture, our team and ultimately our success. When you join, you will get to see and impact every aspect of the business. At KeepSafe everything you do counts.


KeepSafe's current success shows how one specific solution design can create millions of happy customers. We're setting out to provide a solution to a fundamental problem. We want to create a service for people to control their privacy in the digital future, in a way that is natural and easy.


KeepSafe is the hardest we've worked in our lives but this is also the most productive and fun time we've ever had. That's because we have the freedom to work in a way that suits us best. You should too. Make an impact. You're free to decide how. You are free to decide with what tools. You are free to decide what equipment you need.


We have over 13 million customers and we are backed by strong investors but our team is still very small. Now is a rare opportunity to join a startup with significant traction and still be early enough to come along for the full ride.

Longboards & Beer

Before thinking about starting a company together, Philipp and Zouhair were already close friends over their mutual interest in beer. We make sure that our fridge is always stocked. When a friend left his board in our office, we discovered that starting skating at age 30 is not so hard and we fell in love with longboarding. When you join, a board will be waiting for you.

How we work

It's only work when you're not having fun. At KeepSafe, we're maximizing for fun.

Everyone on this team wants to make this the best time in their lives, the most successful, the most productive but first and foremost it should be the most fun. We have fun building a product we love, we have fun working with each other, and we definitely have fun when sharing one (or maybe one too many) beers!

Our challenge lies in creating the service that people use to control their privacy in the digital future, in a way that is natural, easy and intuitive. Our challenge lies in creating products that address real, specific needs without users feeling all the work we're doing behind the scenes to connect, protect their data and make it more useful.

We are product builders and we want to make users happy. Our success comes from our drive to learn and improve. Build, learn, improve, repeat.
