You will develop and enhance mobile SDK technology used across millions of devices worldwide, helping businesses strengthen fraud prevention and digital identity solutions.

  • Enhance existing Java and Objective-C codebases, progressively expanding expertise across both platforms.
  • Work with native C/C++ components, JNI integrations, and modern Kotlin/Swift integration layers.

  • Collaborate with international engineering teams to deliver scalable, reliable software solutions.

Qualifications & Experience:

  • 4+ years of professional software development experience, including strong mobile engineering expertise.
  • Advanced development skills in either Android (Java) or iOS (Objective-C), with a willingness to learn and contribute to the other platform.
  • Solid understanding of mobile architecture, application lifecycles, APIs, performance optimization, and debugging.
  • Experience developing, integrating, or maintaining mobile SDKs, libraries, or frameworks is highly desirable.
  • Familiarity with Kotlin, Swift, C/C++, JNI, or Android NDK is an advantage.
  • Experience with automated testing, CI/CD, Git, multithreading, and networking fundamentals.
  • Strong analytical, problem-solving, and communication skills, with the ability to collaborate in international Agile teams.

What We Offer:

  • Hybrid Working: Enjoy a flexible working environment with three days per week in our Merseburg office.
  • Global Collaboration: Work alongside talented engineers and technology experts across international teams.
  • Meaningful Impact: Develop technology used on millions of mobile devices worldwide to help businesses combat fraud.
