Contract Signal Processing Engineer

Description:

This is a fully remote, 4–6 month contract where you’ll develop and optimize real-time audio and ultrasonic DSP algorithms for TWS platforms. You’ll work hands-on with embedded firmware (C programming), collaborate with international hardware and software teams, and contribute to innovative audio solutions. Collaboration occurs online during European daytime hours, requiring clear English communication.

Key Responsibilities:

• Design and refine DSP algorithms for TWS earbuds.
• Develop embedded firmware in C for low-power DSPs and microcontrollers.
• Integrate and validate DSP components with hardware teams.
• Debug firmware/system issues related to signal quality and latency.
• Contribute to future architecture concepts and performance testing.

Required Skills & Experience:

• Proven experience in audio signal processing or embedded DSP, ideally in consumer audio/wireless devices.
• Strong knowledge of TWS technology (pairing, synchronization, latency management).
• Experience with WuQi chipset or similar platforms (e.g., Qualcomm QCC, BES, Airoha) is a plus.
• Proficiency in Embedded C for real-time, resource-constrained systems.
• Ability to analyze, debug, and optimize audio pipelines.
