• Co-develop and/or work within complex, multi-threaded, multi-processor architectures and audio frameworks to integrate DSP algorithms and control structures
• Develop production ready software following a defined software development process
• Design software features and architectures for an audio amplifier platform based on interpretation of customer requirements and/or technology development initiatives.
• Resolve design conflicts arising from multiple requirement sources and maximize code re-use, flexibility and scalability
• Conceptualize multiple use cases to design a single system to suit many uses.
• Analyze and resolve incompatibility and conflicts between individual DSP algorithms under various modes of system operation
• Estimate processing resources including MIPS, ROM and RAM
• Optimize individual algorithms and total system performance
• Analyze performance impacts of block size, sample rate, memory organization, cache usage and code structure
• Analyze multiple approaches to a problem and chose the best solution based on experience and sound engineering practices
• Present and defend technical decisions to peers and engineering management using facts
• Integrate DSP algorithms with an audio framework, control software and tuning structure and extend the framework as necessary
• Ensure all system components are diagnosable during development and once deployed.
• Work closely with other engineering groups to ensure total tuned system performance
• Develop test plans and appropriate test vectors for independent validation of audio features.
• Perform regression and integration tests on audio features and systems.
