About the Role
As a Senior 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
