Working with pEp

This is a list of current needs, tasks and job offers. Not everything is listed here, and some things are only mentioned briefly. Please ask if you don’t see yourself / your skills in this list, but still would like to work with us!

See some proper job offers on the page of

What’s pEp? Pretty Easy Privacy? Privacy by Default?

  • Everything is free software mostly under some GNU licenses
  • It’s about mass-encryption and mass-anonymization (“for the masses”) and therefore the main goal is to save the world ;)
  • We work in various-offices in mid-Europe and sometimes remotely/distributed
  • Working language English is required, any other languages are helpful (German, Spanish, Catalan, French, etc)

(Security) Code Audits (mainly C++)

Recommendations and offers are very welcome: We’re looking for people and organizations that can do software code audits (ideally focussed on security aspects). Languages mainly C, C++, Rust, but also the app languages like Java, C# etc. Can be split up depending on skills/wishes.

Get more Details on each piece that needs audit here

Single tasks

Some of the mentioned things would also be also possible on a short-term cooperation, e.g. adding pEp via phython adapter to Mutt mailclient or other implementations if MUAs and/or writing adapters.

Some notes and links…

…on pEp’s Tech & Architecture:

  • on the very bottom is the engine (which has e.g. Sequoia underneath)
  • then there are Adapters to include…
  • …apps that come on top

The adapters connect an app with the engine. A simple API allows for easy integration in many languages and development environments. This multi-tier architecture enables developers of add-ons, plug-ins, apps and any other front end solution to have p≡p’s cryptographic functionalities without dealing with the crypto directly; the interfacing adapter does the job. So far there are the following adapters and apps:

…on code repositories

There are various places (for various reasons) where we store the code:

…on IETF Internet Drafts (RFCs)

We have various Internet Drafts open for comments, here are all few of them - there you can also get to know about pEp’s concepts in high detail:

Find some more in our repository for the Internet Drafts:

…on the organizational structure

  • there is a foundation that own most of the code (engine and adapter code)
  • there is a company that owns some of the application code and provides services etc.
  • your employment depends on the task you’re looking at :)

There is one main difference between foundation and company:

  • Foundation has to save the world even without gaining money

    • Versus
  • Company has to gain money even without saving the world (but, regarding the contracts between the two the company also has to save the world :D)

…on geographical structure


Generally most positions are in Barcelona (Dev), Luxembourg (Services) and Nürnberg (Java). As long as you able and willing to travel & your skills match perfectly, we are flexible for other options, too.

There are offices in…

  • Luxemburg (mainly Software Services)
  • Barcelona (mainly Development)
  • Nürnberg (mainly FinpEp Development)
  • Zürich (Development as well as Foundation- and Company-services)
  • Berlin (not an office, some people use “onionspace” there)


Your residency-status (registered/legal address) defines your employment pattern. Possible is Switzerland, Spain, Luxembourg, Germany, other EU-Countries, as well as USA.

Be aware: If you do not have an EU-/ US-working-permit it will be hard for us to employ you :( But if your skills match just perfect, do not hesitate to contact us, and we’ll see what we can do!

…on working structure

As a distributed team we use online tools like IRC, Bugtrackers (Jira), Pads, Wikis and Filestorages, and so on. Working hours are defined within your team and co-workers and can be adjusted with according flexibility as required.

…more notes on “What’s pEp about?”

p≡p is changing the defaults:

p≡p makes digital privacy easy and empowers users and developers to have privacy running on Open Source software.

Generally, p≡p plans to support multiple platforms (iOS, Android, Linux, BSD, MacOS, Windows), programming environments, crypto technologies, and message transports. p≡p doesn’t aim to replace existing crypto tools per se, but stays compatible with existing standards whilst not forcing anyone into vendor lock-in. By design, p≡p is peer-to-peer, end-to-end encrypted and does not rely on any central infrastructure. Secure synchronization of keys and configuration are in development too.

p≡p’s protocols can be implemented by any communication software. These protocols automate the steps taught to users at Cryptoparties to protect personal security and privacy. Thus, p≡p provides protection on a state-of-the-art encryption level for a substantial portion of today’s communication needs – regardless of the user’s technical know-how. For developers, simple APIs allow easy integration of p≡p’s cryptographic functions: They can add easy-to-use encryption by default to their software with only minor expertise on cryptography and security.

Some Quotes that are important to us

Human Rights, Art.12

" No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence, nor to attacks upon his honour and reputation. Everyone has the right to the protection of the law against such interference or attacks. "

Cypherpunk Manifesto (1993):

Privacy Is Not Secrecy.

  • “A private matter is something one doesn’t want the whole world to know, but a secret matter is something one doesn’t want anybody to know. Privacy is the power to selectively reveal oneself to the world.” ()shortened)
  • “We know that someone has to write software to defend privacy, and we’re going to write it.”"
