About Open-Xchange


With some 230 employees Open-Xchange develops a Open-Source-Software addressing communication, collaboration and office-productivity. Sales are made through Internet service providers, hosting, telecommunication and cable providers, which offer their customers the Open-Xchange solution as SaaS (Software as a Service). More than 200 million users adopted Open-Xchange software for their private and business communications via partners such as 1 & 1, STRATO, Host Europe, NetCologne, network solutions / web.com and Rackspace.

The core offer is named OX App Suite with applications for processing e-mails, contacts and appointments, which can be extended by functions like: OX Drive for managing and synchronizing documents, images, photos and movies; OX Documents for text processing, spreadsheets and presentations and OX Guard for encrypting emails and files. Software from Dovecot and PowerDNS are complementing Open-Xchange's portfolio.

We want to constantly advance and are looking for people who have fun working with the latest technologies in an international team. There are locations in Hamburg, Bremen, Dortmund, Cologne, Olpe and Nuremberg as well as Finland, France, the Netherlands, Italy and Spain. International offices are in Tokyo, Sydney and Palo Alto which represents the distributed team in the USA.

If you are interested, please contact Jochen F. Schude for further information - or send us your paperless application with a cover letter including the job ID, tabular CV, certificates, salary request and the earliest possible date of entry by e-mail to recruiting@open-xchange.com.

Everybody counts

The Open-Xchange culture is enforced by you. Your conviction and your engagement are the foundation of our mutual success.

Work at your pace

Flexible job models offer every employee to live up to their personal work live balance.

You, me and we learn; all the time & everywhere

Each employee is invited and should improve and extend their knowledge.

Home office

Up to 2 day of home-office per week are custom.

It’s in the mix

Open-Xchanges success is based – among other reasons – on its sane, open-minded and international melange of employees.

Flat hierachies

Sounds easy but its tricky. We chose this concept to ensure our mutual success and to deal with your ideas and concerns in a respectful and solution oriented manner.

Where in the world do you want to work

Success is fun and we have a lot of it

Besides the yearly OX-Partner-Summit we all gather at one of our European locations to „workshop“, „meet & greet“ and „network“; getting to know each other even better whilst celebrating our individual and mutual successes.
