Full Job Description

đź“‹ Description

  • • Are you a seasoned Mobile Developer with a passion for crafting exceptional user experiences on both iOS and Android platforms? Do you thrive in collaborative, multidisciplinary environments where innovation and problem-solving are at the forefront? Reaktor Innovations Oy, an award-winning tech community, is seeking an experienced Mobile Developer to join our dynamic Gaming & Entertainment Business Unit. This is a unique opportunity to contribute to cutting-edge projects, work directly with clients, and shape the future of mobile applications within a supportive, low-hierarchy culture.
  • • As a Mobile Developer at Reaktor, you will be instrumental in supporting our clients within the vibrant Gaming & Entertainment sector. Your role will extend beyond mere implementation; you will be a key contributor to the entire development lifecycle, from initial concepting and architectural design to iterative delivery and ongoing maintenance. You will have the chance to immerse yourself in complex challenges, leveraging your deep technical expertise to build robust, scalable, and engaging mobile applications.
  • • Your day-to-day responsibilities will be diverse and impactful. You will be actively involved in developing native mobile applications for both iOS and Android, ensuring a high-quality user experience across both ecosystems. A significant aspect of your role will involve collaborating directly with clients and stakeholders. This isn't just about taking orders; it's about actively participating in team settings to clarify ambiguous requirements, understand business needs, and translate them into effective technical solutions. Your insights and expertise will be crucial in navigating the complexities of client projects and ensuring successful outcomes.
  • • Furthermore, you will contribute significantly to architectural decisions and the long-term technical direction of projects. This means thinking critically about scalability, maintainability, and future-proofing applications. You will participate in the crucial phases of discovery and concepting, helping to define the vision and strategy for new mobile initiatives. Your involvement in iterative delivery ensures that we are constantly refining and improving our products based on feedback and evolving requirements.
  • • While your primary focus will be mobile development, we value a holistic approach. You will occasionally have the opportunity to contribute beyond mobile development when a project benefits from full-stack thinking. This cross-stack proficiency allows for a broader understanding of the application landscape and enables you to contribute more comprehensively to team goals.
  • • To truly thrive in this position, a strong technical foundation is essential. We are looking for individuals with solid practical experience in both iOS and Android development environments. This typically translates to approximately 8 years of professional experience, demonstrating a deep understanding of the nuances of each platform. Your technical toolkit should include extensive experience with Swift, UIKit, and Reactive Programming for iOS, as well as Java and Kotlin for Android. While experience with SwiftUI is considered a plus, a proven ability to deliver high-quality native applications is paramount.
  • • We also emphasize a testing ownership mindset. This means taking full responsibility for the entire development cycle, from writing clean, efficient code to ensuring that features are defect-free and successfully shipped to users. Your commitment to quality will be reflected in your approach to testing, debugging, and overall application stability. Experience with production app monitoring and troubleshooting is highly valued, as it demonstrates your ability to maintain and optimize live applications.
  • • For those with a keen eye for detail and a passion for user interface design, an interest in building polished animations and working closely with Motion Designers will be a significant asset. This collaborative approach to UI/UX ensures that the applications we build are not only functional but also visually stunning and engaging.
  • • Beyond native development, a solid practical experience with C++ and Flutter is also beneficial, showcasing a broader technical depth. Your familiarity with full-stack development principles will enable you to contribute more effectively within a team, understanding the interconnectedness of different application layers.
  • • Crucially, we seek individuals with a consultative mindset. This involves experience engaging with multiple stakeholders to solve challenging, ambiguous problems. Your ability to listen, analyze, and propose effective solutions will be key to your success. Excellent communication skills are vital, particularly fluent verbal and written English, to facilitate seamless collaboration within our international environment. While local language proficiency (Finnish) is a plus, it is not a strict requirement.
  • • Finally, adaptability is key. We operate in a hybrid setup, requiring a willingness to balance work across the office, client premises, and remote settings. This flexibility ensures we can meet the diverse needs of our projects and clients while maintaining a healthy work-life integration.
