Job description

Job Title: Junior Game Developer (Java / libGDX)


Job Type: Contractor


Location: Remote


Job Summary: In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.


Key Responsibilities:

  1. Develop, maintain, and optimize simple 2D game features using Java and libGDX frameworks.
  2. Collaborate closely with AI specialists to design engaging game interactions and collect high-quality training data.
  3. Implement basic game mechanics including sprite management, game loops, and input handling.
  4. Troubleshoot and debug code to ensure optimal performance and reliability of game modules.
  5. Participate in code reviews and contribute to the improvement of internal coding standards.
  6. Document technical processes and game development workflows clearly for cross-functional teams.
  7. Communicate effectively with team members, providing regular status updates and seeking feedback.



Required Skills and Qualifications:

  1. Basic knowledge of Java programming and object-oriented principles.
  2. Hands-on experience with libGDX through coursework, personal projects, or prototypes.
  3. Understanding of fundamental game development concepts such as game loops, sprites, and input management.
  4. Strong written and verbal communication skills, with a focus on clear technical documentation.
  5. Ability to work collaboratively in a fully remote team environment.
  6. Demonstrated interest and initiative in building games or interactive applications.
  7. Willingness to complete an AI interview as part of the selection process.



Preferred Qualifications:

  1. Portfolio of small games or demo projects (GitHub links or playable demos encouraged).
  2. Familiarity with vectors, collision detection, or basic 2D physics.
  3. Experience using Git for version control and collaborative development.
