About the Role
As a 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.
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
Perform regression and integration tests on audio features and systems
Create models and documentation suitable for other developers to create an implementation
What You Need
Bachelors degree in electrical engineering, computer science, or equivalent
4-8 years overall experience
4+ years of embedded software development or testing
4+ years of C/C++ or other structured language
4+ years of experience in the DSP and/or audio field
Experience developing consumer products
Experience with tuning/calibrating systems of algorithms
Knowledge of features, strengths and weaknesses of various DSP platforms and algorithm approaches
Knowledge of embedded system debuggers, emulators, compilers, etc.
Working knowledge of embedded operating systems (schedulers, memory management, driver models, RTOS concepts
Experienced working with and/or leading off-shore development teams
Creative problem-solver capable of creating and reproducing complex software defects
What is Nice to Have
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
Able to read schematics and debug analog and digital hardware
Experience with multi-core System-on-Chip processors
Experience developing automotive or military products
Experience with SPICE compatible software development practices
Working knowledge of personal computing and mobile device platforms
Expert in MATLAB and Simulink
Deep knowledge of digital communication protocols: I2C, I2S, SPI, UART, USB, BT
Working knowledge of automotive networks: CAN, LIN, Ethernet, TCP/IP, MOST
Deep knowledge of audio systems and acoustic principles
Very good knowledge of amplifier hardware concepts including data converters, power supplies, output stages and analog filter design.
Employment Type: Full Time, Permanent
