Embedded Engineer for Dolby Decoding & ADAU chips (Sigma Studio)

Hiring: Embedded DSP & Hardware Engineer

(Full-Time | Audio Systems | ADAU1701 | Networked Amplifiers)

We are building the next generation of network-controlled audio amplification systems and are looking for a full-time Embedded DSP & Hardware Engineer to join our core engineering team.

One of the immediate projects involves developing a complete end-to-end solution around the ADAU1701 DSP, programmed via SigmaStudio, including custom PCB design and a web-based control interface.

This is not a freelance task. This is a long-term product-building role.

What Youll Lead

Custom PCB design integrating:

• ADAU1701 DSP
• MCU (ESP32 / STM32 or similar)
• I2C communication
• WiFi / Ethernet connectivity
• Audio-grade power + grounding architecture

Firmware development:

• SigmaStudio TCP/IP protocol implementation
• Real-time DSP parameter control
• Preset storage & recall
• Reliable network communication

System architecture:

• Web dashboard MCU DSP communication
• Multi-device control over LAN
• Scalable amplifier ecosystem

Development of additional audio hardware products (future roadmap)

Who This Role Is For

• Engineers experienced with ADAU1701 + SigmaStudio/SigmaStudio+
• Strong embedded firmware developers (ESP32 / STM32, etc)
• PCB designers comfortable with mixed-signal & audio layouts
• Engineers who enjoy building real, shipping hardware products
• Bonus: Experience in commercial or consumer audio systems

Role Details

• Full-time position
• Long-term product roadmap
• Opportunity to architect future audio platforms
