While working at Reaktor, we’ll provide you with:
To be able to impact how you work. Together with the client, your team chooses the approach, technologies, and methodologies you think will work best in any given situation
A community with as much support as your heart desires
A team that’s not only experienced but considerate as well - they all want you to succeed
A sustainable work-life balance and support for your daily life outside of work. (e.g., free moving day, Reaktor car share, sick child care services, office space to use for your private events, etc.)
An opportunity to grow as a professional. In addition to the day-to-day work, we offer internal training courses, community events, and 15-minute coffee breaks to discuss hot topics in tech and design
A possibility to take part in more extended academy-like studies like Cloud Academy.
300+ hobby clubs, from winter swimming and running to knitting and archery, that bring people together outside of (and sometimes inside) office hours. Many of these are supported by Reaktor
Diversity, equity, and inclusion
Together, we are committed to making Reaktor an environment that embraces and values all of our employees for the whole of who they are. We encourage applicants from all backgrounds to apply, knowing that studies show that members of underrepresented communities don’t apply for jobs unless they fully satisfy all of the requirements.
