Description & Requirements

DSP SW Engineer (GG 10b)

About the Role

• As a DSP Software Engineer, you will be working on software products that will be developed on OEM IVI/HU 
and amplifiers. Products typically consist of microcontrollers, SoC, for configuration, communication and control 
and a DSP processor for audio processing.
• Software development involves working with complex, multi-threaded, multi-processor or multi-core 
architectures and audio frameworks to integrate DSP algorithms and control structures.
What You Will Do 
• Customize and integrate audio DSP algorithms for the automotive environment within complex, multi-threaded, 
multi-processor architectures and audio frameworks
• Port and optimize DSP algorithms to various processors/platforms and make use of available resources, 
peripherals, accelerators, compiler features, etc
• Definition and design of audio signal flows and software architectures using SW platform components
• Develop production ready software following a defined software development process
• Resolve design conflicts arising from multiple requirement sources and maximize code re-use, flexibility and 
• 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 and optimize individual algorithms and total 
system performance
• Analyze performance impacts of block size, sample rate, memory organization, cache usage and code structure
• Ensure all system components are diagnosable during development and once deployed
• Work closely with other engineering groups to ensure total tuned system performance
• Perform regression and integration tests on audio features and systems
• Reverse-engineer designs from legacy software
• Communicate with peers inside the HARMAN group to coordinate software development. 
Basic Qualifications:
• Bachelor’s degree in electrical engineering, computer science, or equivalent
• 6 years of embedded software development
• 4 years of C++/C or other structured language
• 3 years of experience in the DSP and preferably in the audio field
• Experience developing consumer products
• Deep knowledge of filtering, audio processing/post processing, noise control 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
• Expert in several embedded system debuggers, emulators, compilers, etc.
• Working knowledge of embedded operating systems (schedulers, memory management, driver models, RTOS 
• Experience with multi-core System-on-Chip processors
• Experience with digital communication protocols in multiprocessor environment: I2C, I2S, SPI, UART, USB, 
• Knowledge of CPU and DSP/GPU inter processor communication, Experience in dealing with Inter processor 
communication and synchronization
Desired Competencies:
• Experience developing automotive products
• Experience with SPICE compatible software development practices
• Proficient in MATLAB and Simulink
• Good knowledge of Android HAL and lower layers
• Good knowledge of amplifier hardware concepts including data converters, power supplies, output stages and 
analog filter design
• Dedicated performer with the ability to advocate appropriately for product quality.
• Relentless learner with a dedication to learn new technologies and test methods
• Self-driven and Innovative to drive continuous improvements in Test process
• Resourcefulness in triaging problems and coordinating with multiple teams for issue resolution
• Strong written, verbal communication and interpersonal relationship skills
