Firmware development & architecture

• Lead the firmware development and architecture across our existing and future product portfolio

• Architect and develop modular embedded software on top of real-time operating systems (FreeRTOS, Zephyr)

• Develop drivers and BSP across chipsets and peripherals (I2S, I2C, SPI, UART, USB), including bring-up and integration of new hardware

New technologies

• Investigate and explore new firmware-related technologies

• Work primarily with Bluetooth (BT Classic, BLE, Auracast), and explore other wireless technologies for audio streaming in consumer products

• Evaluate new SoCs, tools, and environments for system-level platforms (MCU, wireless radios, DSP, peripherals)

Collaboration

• Work across internal and external teams covering hardware, app, and manufacturing test

• Support development of test tools and systems

In order to become a success in this role, we believe that your profile should be aligned with the bullets listed below. However, we acknowledge that success can take many forms, so please do apply even if you don’t tick all the boxes.

• You’re an expert in C, and you’ve worked with tools like Git, Make, CMake, Docker, and the GCC toolchain

• You’ve worked with embedded systems, including RTOS (preferably FreeRTOS or Zephyr), and you’re comfortable debugging on real hardware

• You bring relevant education or similar hands-on experience, 5+ years working with firmware or embedded software (ideally in consumer audio or something close)

• You’ve built actual products before, ideally in consumer electronics, and you have a general feel for audio concepts and terminology

• It’s a plus if you’ve worked with CI/CD, Bluetooth on embedded devices, or languages like Rust and C++

• You’re comfortable sharing what you know and learning from others

• You can communicate clearly, no matter if in a discussion or when presenting ideas

• You’re okay working in environments where things aren’t always fully defined, and can still move things forward
