EPS Software Engineering AG is your proficient partner for consulting, concept creation, analysis, development, testing, documentation and maintenance of software in the technical environment.

EPS is one of the largest independent software developers in Eastern Switzerland and has been creating innovative, customized software solutions in the technical environment for its customers for over 50 years. The variety of projects fascinate our engineers with each coming day.

Our size not only guarantees stability, continuity, extensive know-how and proven experience, it also guarantees optimal organization and infrastructure. At the same time we are small enough to be flexible, efficient and personal with each customer..

Precision to Perfection

It's the attitude

Precision in perfection is what EPS strives for when it comes to its customers. To achieve this, EPS employees put all their motivation, passion, talent, knowledge, empathy and experience to work. The management provides the magical mix, the brilliant environment and the standards in the form of a quality system. Do you think it's a bit extreme? We know challenging ourselves with these goals stimulate us to do better and work harder.


Regional and personal

Drinking a coffee together, having a casual conversation, cultivating social issues - in short, sharing identical values. This makes collaboration precise, intensive, qualitative, effective and efficient. Switzerland is one of the most expensive countries and we know only outstanding products have a chance on the world market. These products are created by top teams, and these teams grow together a lot quicker when they are close to their customers. Do our opinions coincide? Then we should get to know each other.

QS ISO 9001


Guaranteed quality and safety is a matter of high importance to us - our ISO 9001 certificate also vouches this. For EPS, quality means driving projects forward efficiently and with optimum customer benefit. Our quality assurance system supports the team members in their daily work.


Atlassian Solution Partner

Teamwork - faster and smarter

The Atlassian products were introduced into EPS in 2013 and our vision was to create all documents in Confluence. Of course EPS customers do not want their quotations in the form of wiki pages, but similar to the rest of the world, in PDF form. With the construction of Confluence apps EPS has achieved this ambitious goal and thus significantly advanced the level of teamwork.

In 2017, EPS officially became an Atlassian Solution Partner and is looking forward to supporting you in the introduction of Jira, Confluence, Bitbucket, Bamboo, Jira Service, etc into your company.



Evolved over five decades

EPS combines over forty years of experience with the current expertise of our employees to service clients and create complex software. This gives us confidence in dealing with complex tasks. In addition, our experience in a wide variety of application areas allow us to view new projects without bias and to develop innovative solutions for our clients.
