But we couldn't do it without our extraordinary workforce - and that's where you come in. Join our team and help us continue to make Cirrus Logic an exceptional place to grow your career!
Cirrus Logic is seeking a candidate for our audio solutions development team. Candidate will be using MATLAB, Python and real-time DSP/firmware development tools to design and develop leading-edge audio processing software targeted for Cirrus Logic ICs. Candidate must be able to work equally well in either independent or team efforts. Candidate must be insightful and highly effective at communicating ideas and resolving problems.
Responsibilities
  • Develop and test real-time embedded firmware for Cirrus Logic ICs.
  • Build host-side applications to test and demonstrate embedded firmware.
  • Support customer demonstrations, integration and field engineering efforts.
  • Real-time testing and analysis of audio processing software.
  • Participate in reviews of own or others' code and documentation

Required Skills and Qualifications
  • BS or MS in Computer Science, Electrical Engineering, or related field.
  • 5+ years of experience in real-time embedded development.
  • Experience developing and documenting signal processing algorithms for DSP platforms.
  • Advanced proficiency in C programming and solid Python skills.
  • Experience using MATLAB for algorithm development, prototyping and testing.
  • Excellent communication and documentation abilities.

Preferred Skills and Qualifications
  • Experience with classical machine learning techniques and modern neural network architectures for audio processing.
  • Experience with production software in a Continuous Integration (CI) environment.
  • Familiarity with Git, Visual Studio, Visual Studio Code, and PyTorch.
  • Knowledge of debugging tools (JTAG, SWD, GDB) and peripheral interfaces (SPI, I2C, etc.).
  • Experience with audio related electronics (codecs, filters, amplifiers, etc.)

Export control restrictions based upon applicable laws and regulations would prohibit candidates who are nationals of certain embargoed countries from working in this position without Cirrus Logic first obtaining an export license. Candidates for this role must be able to access technical data without a requirement for an export license. We are unable to sponsor or obtain export licenses for this role.
