Requirements
• 5+ years of job experience in Java development • Knowledge how to write clean and maintainable code (best practices, TDD, design patterns) • General understanding and knowledge of the Java ecosystem (frameworks, libraries, services) • Experience with Kotlin • Solid SQL knowledge (SQLite, MySQL, PostgreSQL) • Multi-threaded development experience - threads, coroutines, Rx, Java streams • Supporting technologies - REST, JSON, XML, HTML, Git • Knowledge of Linux, common tools, and it's ecosystem • Fluent in English • Develop new features and maintain console applications and utilities • Research into current and upcoming technologies like AI, big-data, 3D, media formats, etc. • Write maintainable, high performance and high quality code using best practices, SOLID, tests, code reviews, clean architecture, etc. • Communicate within the team to clarify complex technical questions and collaborate on solutions. • Work with development processes and tools like SCRUM, Jira, Git, IDEs, etc. • Write Java, Kotlin and Python code when needed • Prepare code and prototypes from AI researchers for production use • Continuously learn and improve your skills (with support from teammates whenever needed). • Process data from APIs, databases, JSON, XML, and other sources. • Transform assets (images, 3D models, videos, etc.) into different formats • Import and export of 2D/3D data from and to .dxf/.dwg/.blend formats • Write a Blender plugin to load data and provide additional modeling functionality. • Write high performance code using CPU and GPU to the max (using parallel, concurrent programming like coroutines, threads, Rx, promises, futures, etc.) • Build processing pipelines, where multiple threads are used to max out CPUs and do lots of different processing on multiple threads/coroutines/Rx/java streams/etc. • Experience with Python, C / C++ languages • Experience with popular libraries like Spring, Dagger, JUnit, Apache Commons • Understanding of 2D / 3D technologies and software (for example OpenGL, WebGL, Raytracing, Blender) • Understanding of Mathematics, Geometry, Computer Vision • Understanding of Kubernetes, Docker and nearby technologies • Love what you do: We're looking for team members who truly enjoy their work and bring that enthusiasm to the team every day. • Tech geek at heart: If coding, experimenting with new software tools, or curious about tech trends is your thing, you're speaking our language. • With solution-oriented mindset: When you are faced with challenges, you start thinking of possible solutions instead of dwelling on the problems. • Have tech hobbies? Yes, Please!: programming, micro-controllers, 3D printing, physics, mathematics, etc. • Team Player Who Gets It: We value team members who can grasp tasks quickly and communicate their ideas effectively – teamwork makes the dream work!
