The plus side of working at EnAppSys

You can grow

We strive to be an innovative company and want you to grow with us. Together, we’ll look at the goals you want to achieve and work out how to get there. Mentoring and plenty of training opportunities will ensure you succeed.

You can count on us

We’re not only going the extra mile for our clients, but also for you. As colleagues and a company, we support each other even outside our working hours. Most people who join us stay here for a long time, and we’re happy to reward this loyalty.

You can be yourself

EnAppSys prides itself on its warm, welcoming environment. With people of all ages and from various backgrounds, we make sure you can be yourself. You’ll be joining a flat structure where you’re allowed and even encouraged to speak your mind. We’re not just colleagues; we’re a group of friends who happen to work together.

You can have fun

It’s not all work and no play at EnAppSys. We have a Christmas get-together each year and teambuilding activities whenever possible. We also have a virtual ‘elevenses’ meeting every week where the team can share any work and other announcements. If you’re in the office, prepare yourself for lots of tea and the occasional baked delight.



Our recruitment process

Applicants will need to successfully complete a few stages before becoming an EnAppSys employee. There may be exceptions based on your profile or the role you’re applying for, but most of our candidates go through the following procedure.


  1. You apply through one of our job postings on this page. An automated response is sent to you to inform you that we’ve received your application.
  2. After examining your resume and cover letter, we will contact you to set up a more general phone interview. You’ll talk with a panel consisting of our recruiter, the head of department and maybe an employee.
  3. If you pass these first two hurdles, we set up a second and final – more focused – interview. This will usually be in person so you can also meet your future colleagues. We’ll also ask you to complete a couple of tests in this stage.
  4. If you’re the best person for the job, we make you an offer and hope to welcome you as a member of our team soon!
