We simply offer more than just a high salary and greater freedom; that’s just the beginning. With us, you’ll find the work environment and opportunities you deserve. Welcome to Deploja, where the grass is indeed greener!

Vi erbjuder dig följande, Valet är ditt!

• Exciting assignments with our many clients. We focus on long-term projects, which gives you the opportunity to create value for the client while also developing yourself.

• Company car – we encourage you to choose an electric car for a more sustainable future.
• Occupational pension and great opportunities for salary conversion.
• Vacation – Would you like more than 30 days of vacation, perhaps 60 days?
• Private health insurance, accident insurance, and life insurance for increased security.
• Skills development – you set your own budget and choose the training you wish to attend.
• Quality of life – Are you struggling to balance everyday life and wish to work a little less while still earning as much, if not more?

We handle applications continuously, and due to the high workload, it's especially important to include a short motivation for the position, explaining how you meet the requirements.
