The Audio Firmware Engineer will develop and optimize audio processing pipelines for camera and doorbell products, focusing on implementing advanced audio algorithms and DSP solutions to ensure high-quality audio performance. This role involves collaboration with hardware and software engineers in an agile environment to design and manufacture embedded Linux devices.
Key Responsibilities
- Collaborate with hardware engineers and software engineers to design and manufacture embedded Linux devices.
- Design and implement features that interact with cloud-based systems.
- Work with product managers and quality engineers to ensure products meet company standards.
- Communicate effectively and collaborate with team members to ensure timely delivery of projects.
- Implement adaptive filters, DSP algorithms, and echo cancellation systems for audio processing.
- Design and implement algorithms and corresponding firmware for high-performance audio solutions.
Requirements
- Masters degree in Computer Science, Electrical Computer Engineering, or a related field or equivalent experience.
- 5-15 years of experience in audio algorithm development for consumer products.
- Must have experience working on audio processing pipelines for one or more devices.
- Expertise in digital signal processing (DSP) techniques and audio algorithms, such as Acoustic Echo Cancellation (AEC), Active Noise Reduction (ANR), and Automatic Gain Control (AGC).
- Strong proficiency in programming languages like C and C++.
- Hands-on experience with real-time operating systems (RTOS), microcontroller programming, and hardware-software interaction.
- Knowledge of audio codecs such as µLaw, aLaw, Opus, AAC, and MP3.
- Experience with Linux-based operating systems for embedded development.
- In-depth understanding of adaptive filters and their implementation in DSP for echo cancellation.
- Experience designing audio processing pipelines for embedded systems.
- Familiarity with electronic circuits, microprocessors, and digital/analog audio paths.
- Familiarity with development tools such as IDEs, version control systems (e.g., Git), and bug tracking systems.
- Strong problem-solving skills and attention to detail.
- Good understanding of data structures and algorithms.
- Excellent communication skills, both verbal and written.
- Experience with Agile or Scrum methodologies.
- Understanding of audio testing requirements, such as minimizing vibration and audio feedback paths in enclosed systems.
- Knowledge of basic speaker chamber design for optimal frequency response and vibration isolation.
