About the Role

As a Principal DSP Software Engineer you will work on products that will be developed for OEM automotive amplifiers and other similar audio processing products.  Products typically consist of a microcontroller for configuration, communication and control and a DSP processor for audio processing.  Software development work will be mainly working within complex, multi-threaded, multi-processor or multi-core architectures and audio frameworks to integrate DSP algorithms and control structures.

Your Team

This position does not have any direct or indirect reports; but principal level engineers are expected to mentor more junior engineers and help guide their careers and activities.

What You Will Do

• Develop and integrate audio DSP algorithms for the automotive environment
• 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
• Create models and documentation suitable for other developers to create an implementation
• Reverse-engineer designs from legacy software
• Drive peer review of designs. Be an expert authority in reviews of team member contributions
• Supervise and review contributions from the development team
• Provide estimates of group programming effort to size the scope of projects
• Port and optimize DSP algorithms to various processors and make use of available resources, peripherals, accelerators, compiler features, etc
• Investigate new DSP audio related technologies and best practices
• Create novel software solutions to issues in audio & acoustic systems
• Work with software team leaders to negotiate resolution of issues
• Establish and coordinate activities with third party developers and contractors
• Communicate with peers inside the HARMAN group to coordinate software development. This includes occasional travel for training or coordination with other groups
• Manage small projects and technical resources, including planning, estimating and follow through
• Engineer convincing quick-turn demos using available hardware and software components

What You Need

• Bachelor’s degree in electrical engineering, computer science, or equivalent
• 12-15 years overall experience
• 10+ years of embedded software development or testing
• 10+ years of C/C++ or other structured language
• 10+ years of experience in the DSP and/or audio field
• Experience developing consumer products
• Deep knowledge of filtering, speech processing, noise control and telecommunications algorithms in both time and frequency domains
• Strong understanding of DSP frameworks and how individual DSP algorithms interface and interact with each other, the control software and tool interfaces in an optimized way
• Experience with tuning/calibrating systems of algorithms
• Knowledge of features, strengths and weaknesses of various DSP platforms and algorithm approaches
