Principal Software Engineer, Audio Systems Job at Sonance in San Clemente

As a Senior/Lead Embedded Systems Software Engineer, you will design and build entirely new audio products, from your strong background in both audio hardware and software.

The ideal candidate can write world-class software solutions for Linux and RTOS-based embedded devices. You are proficient at writing efficient low-level code to interface with embedded hardware, including audio related peripherals such as codecs and amplifiers. You are at ease configuring the audio subsystems of Linux, and comfortable developing a proprietary driver or bare metal solution if needed. You are intimately familiar with debug tools and able to perform board bring-ups. As an accomplished troubleshooter, you hunt down bugs on your own. And you do not mind breaking out the oscilloscope and rolling up your sleeves to debug a bus interface.

You are not only a full-stack engineer; you are capable of understanding and beating down any sorts of problems from the metal layer up.

You will be a key contributor to the product roadmap and strategy, drawing from your vast experience of embedded and networked system design, from basic HW/SW integration to services and high-level system applications. You will research and evaluate prospective software packages and technologies. Working with internal and external development partners, you will then architect, integrate, and refine software solutions for our next generation products.

The ideal candidate is passionate about their work and enjoys working with a close-knit team to build great things for the audio industry.
