Summer Job: Hotels Software Engineer Trainee

Examples of what we've been working on lately with Sokos Hotels app: 

• Mobile key 
• Hotel check-in 
• Reservation payments and payment handling 
• Self-service kiosk 
• Business traveler program 

You are curious and analytical, and you communicate effectively in English. You love to build products and solve problems. You see software engineering as a team sport. Working with others is your preferred way to get things done. As our Trainee we expect you to be approaching the end of your engineering studies, and through that a basic understanding of software engineering. While we don’t require prior work experience from the field, all experience in coding counts as your advantage – especially experience in mobile React Native or experience in backend development in the AWS environment. 

What are we looking for? 

You’re curious, analytical, and comfortable communicating in English. You enjoy building products, solving problems, and learning through collaboration. You see software engineering as a team sport and prefer working together to create great products. 

You’re likely approaching the end of your engineering studies and have a basic understanding of software engineering principles. We’re looking for trainees who are interested in continuing their journey with us as Junior Software Engineer after the summer, based on performance and mutual fit. 

While prior professional experience isn’t required, any hands-on coding experience is a plus — especially experience in mobile development with React Native or backend development in an AWS environment. Above all, you’re motivated to learn, grow, and take your first steps towards a longer-term role as a software professional.

• Great work is rewarded, and all our employees are included in a performance-based bonus system.
