  • Develop internal desktop applications in Java and Matlab that aid in loudspeaker design.
  • Maintain and create embedded C++ code for DSP chips, including audio algorithms.


  • Devops experience on a professional environment or open-source project.
  • Version control: you have created and maintained a repo used by multiple users. Experience solving conflicts.
