Junior Signal Processing Engineer – Audio & Ultrasound (Embedded Systems Focus) (f/m/d)

USound is disrupting the audio industry, setting new standards in audio experience, and maximizing the degrees of freedom in manufacturing wearables and hearables.

We are leaders inacoustic solutions based on MEMS speakers.Since 2018, we have been enabling our customers to bring new revolutionary audio products to the market. USound achieves this through radical miniaturization, power reduction, and increased production efficiency.

We are looking for a highly motivated and self-drivenjunior engineer or graduating student with a passion for signal processing, particularly in audio and ultrasonic applications.This is an exciting opportunity to work on real-world problems and develop firmware for cutting-edge embedded systems in a technically challenging environment.

You’ll join a small, focused team and contribute to the design and implementation of digital signal processing features used in consumer devices and wearable technologies. You’ll be expected to learn fast, take initiative, and gradually take ownership of meaningful parts of the project.

Responsibilities

• Support the design, implementation, and testing of signal processing algorithms for audio/ultrasound applications.
• Assist in developing embedded C code for real-time firmware running on microcontrollers or DSP platforms.
• Run experiments, analyze data, and validate algorithm performance under supervision.
• Collaborate with experienced engineers and take part in code reviews and feature planning.
• Gradually grow into taking independent responsibility for features or components.

Experience and Qualifications

• Near completion or recent graduate of a degree in Electrical Engineering, Acoustics, Computer Engineering, or related fields.
• Solid academic knowledge ofdigital signal processing– ideally with project or thesis experience inaudio or ultrasound.
