Senior Staff Engineer System Application Engineering Acoustics (f/m/div)

In this role you will design, implement, and validate advanced audio hardware and embedded firmware, shaping how acoustics integrate with microcontrollers and DSPs. You’ll collaborate with cross-functional teams to develop demonstrators and reference designs that showcase acoustic performance. You will lead system-level characterization and debugging to ensure robust, compliant designs that meet customer needs. This position offers the chance to drive meaningful impact in acoustic solutions for cutting-edge products.

• Own design, development and test of state-of-the-art audio hardware solutions, including MCU, DSP, CODEC, and speaker amplifier selection and design-in
• Lead PCB design for audio-focused systems, ensuring signal integrity, power delivery, and EMI/EMC compliance
• Develop and maintain embedded firmware for audio DSP and MCU platforms, including drivers, codec configuration, and real-time processing pipelines
• Plan and conduct system-level acoustic characterization and debugging using measurement setups and lab equipment
• Collaborate with mechanical, software, and product teams to define system requirements and facilitate integration into demonstrators, evaluation kits, and reference designs

• Technical degree in Electrical Engineering, Embedded Development, Acoustics, or similar
• At least 5 years of work experience in Application Engineering, R&D or Technical Marketing
• Solid understanding of acoustic system design principles, including microphone fundamentals, audio signal chains, and codec/DSP integration
• Hands-on PCB design experience with Altium Designer, KiCad, or OrCAD, high-speed/mixed-signal layout for audio circuits
• Experience with hardware development processes: design requirements, schematic/layout reviews, DVT, and cross-platform integration
• Proficiency in embedded firmware development in C/C++ on ARM Cortex-M, with I2C, SPI, PDM, I2S, TDM interfaces and real-time audio algorithms
• Familiarity with acoustic measurement tools such as Audio Precision APx and interpreting acoustic metrics
• Fluent English (written and spoken); German a plus

• Cross-functional collaboration
• Strong communication
• Problem solving and analytical thinking
• Altium Designer
• KiCad
