Mobile Developer

If you thrive in mobile development, enjoy solving complex challenges in multidisciplinary teams, and are curious to work in a low-hierarchy environment, you might just be what we’re looking for.

You will join our Gaming & Entertainment Business Unit, where you will support clients in this domain.

Your daily tasks include:

• Developing native mobile applications for both iOS and Android

• Collaborating directly with clients and stakeholders to clarify ambiguous requirements, in a team setting

• Contributing to architectural decisions and long-term technical direction

• Participating in discovery, concepting, and iterative delivery — not just implementation

• Occasionally contributing beyond mobile, when the project benefits from full-stack thinking

To thrive in this position, you’ll need:

Technical Expertise:

• Strong experience in both ecosystems (iOS/Android). We notice that it usually takes about 8 years of professional experience to learn these things

• Solid practical experience with: Swift, UIKit, Reactive Programming, Java, Kotlin

• Experience with SwiftUI is a plus

• A testing ownership mindset you take responsibility for the full development cycle, from implementation to ensuring features are defect free and shipped to users

• Experience with production app monitoring and troubleshooting

• Interest in building polished animations, working closely with a Motion Designer

Technical Depth:

• Solid practical experience with: Swift and Kotlin

• Ideally experience in C++ and Flutter

Cross-Stack Proficiency:

• Familiarity with fullstack development.

Consultative Mindset:

• Experience engaging with multiple stakeholders to solve challenging, ambiguous problems.

Communication Skills:

• Fluent verbal and written English to collaborate in an international environment.

• Local language (Finnish) is a plus

Adaptability:

• Willingness to work in a hybrid setup. This means balancing office, client premises, and remote work.

For two decades, we’ve been developing qualities and capabilities for adapting, reacting, and supporting change – building Reaktor to hold up in a fast-paced environment while ensuring the well-being of our people.

While working at Reaktor, we’ll provide you with:

• The ability 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. If you're thinking twice about applying for this reason, we invite you to send us your application anyway. You could be just the person we're looking for. Read more about our DEI work here.
