  • Familiarity with IL2CPP, BURST, and DOTS.

  • Experience in web development fundamentals.

  • Understanding of mobile OS-level features and their limitations.

  • Knowledge of the software lifecycle from code to executable on target systems.

  • Familiarity with mobile file systems, networking stacks, and background services.

  • Knowledge of multithreading, async programming, and performance-efficient rendering techniques on mobile hardware.

  • Experience with build systems like cmake, maven, makefiles, bazel or gradle to be able to collaborate closely with our ML team.
