Immediate vacancies

Due to a significant expansion of its technology base and its establishment of AudioTelligence Ltd, CEDAR Audio Ltd has two immediate vacancies for exciting and significant posts in its software and hardware research and development department. These positions offer significant scope for development in a small but very dynamic company that has led the world in its field since it was founded nearly three decades ago.

Based in the attractive village of Fulbourn with nearby shops and amenities, we offer a pleasant working environment within the Cambridge technology bubble. The corporate environment is relaxed and productive, and we offer flexible working hours to accommodate staff needs.

The company is the recipient of numerous awards including an Academy Award and two Cinema Audio Society Awards, and the successful applicants can expect to contribute to products at the forefront of film and TV production, broadcast, and live sound.

  • coding for dedicated DSP chips
  • experience with embedded SHARC and/or ARM processors
  • FPGA design (preferably Xilinx/VHDL)
  • regulatory compliance including CE, EMC and RoHS
  • 3D modeling and mechanical design

In addition, it will be helpful to have experience in software development for Windows and technical writing skills for which a high standard of English will be essential.

Lead Audio DSP Engineer

The Lead Audio DSP Engineer works with the software and hardware engineering teams to provide DSP algorithms and code for the Company's product lines. This role will require a pro-active individual with a high degree of autonomy and technical ability, but does not involve management or administrative responsibilities. The successful candidate is likely to have relevant academic and/or commercial experience.

Principal responsibilities:

  • R&D of innovative audio DSP algorithms
  • Coding of DSP algorithms in efficient C++

Essential skills and experience will include:

  • a deep understanding of classical and statistical DSP for audio signals
  • DSP algorithm research and development abilities, eg using Python or MATLAB
  • knowledge of audio signals, preferably from a professional audio, music or hi-fi perspective
  • excellent C++ software design and coding (preferably Windows-based)

Other desirable skills and experience will include:

  • coding for embedded platforms such as ARM and/or SHARC
  • knowledge of professional audio software and workflows
