Java/Kotlin Freelancer



Software Engineering
Budapest, Hungary
Posted on Wednesday, May 15, 2024
Our vision is simple yet powerful: we want to create a place where engineers thrive, taking on exciting projects and using the latest technologies, free from the shackles of legacy solutions.
Thanks to the diverse range of industries we work with, our days are never boring: from world-class apps to AR solutions or even programming robots, we’ve got it all covered. We don’t just write code for our screens; rather, we develop impactful products used by millions every day: let them be large-scale public transport applications, leading fintech platforms, or storage solutions contributing to a greener future.
We are a team of 100+ developers (Java, JavaScript, Android, iOS platforms) and QA engineers with our coding fingers at the ready working on the next big thing. We value openness, modesty, hard work, and simple yet great solutions.

Your day to day will include:

  • Pioneering the development of a stable and scalable Java back-end from the ground up
  • Crafting code that adheres to the highest industry standards while ensuring seamless integration with our CI tools
  • Collaborating effectively within a dynamic team environment and engaging in exciting and cutting-edge tech initiatives
  • Bringing an architectural perspective to the planning process
  • Collaborating with and supporting the work of our Tech Leads and Architects

We'd love to meet someone who has:

  • Proficiency in Java (we currently utilize Java 11, 17, 21 alongside Kotlin in our projects)
  • Familiarity with back-end frameworks such as Spring, Micronaut, or similar technologies
  • A strong OOP mindset and a commitment to upholding SOLID principles
  • Hands-on experience with SQL or NoSQL databases
  • A genuine interest in staying up-to-date with the latest industry trends
  • A passion for writing clean code; if you're an Uncle Bob fan, you're more than welcome
  • Knowledge of Kotlin (this is a big plus)
  • Expertise in Containerization and Kubernetes (that would be a significant advantage)
  • At least an intermediate level of English language skills since our team operates internationally
