About the role
- Audio is a critical component of human-robot interaction, enabling speech recognition, localization, communication, and environmental awareness in dynamic real-world environments.
- Your work will span concept development, prototyping, validation, system integration, and production deployment, ensuring high-quality audio performance across diverse environments and operating conditions.
- Your contributions will directly impact NEO's ability to hear, understand, and communicate effectively with the people around it.
Responsibilities
- We're building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back.
- NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people.
- We're scaling, we're hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.
- The systems you build will directly shape how humans interact with robots every day.
- Own the audio hardware and firmware systems that enable seamless communication between humans and robots.
Requirements
- Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline
- Extensive experience designing audio hardware systems, including microphones, speakers, and associated signal chains
- Strong hands-on experience with audio measurement and validation equipment
- Experience working with real-time audio streaming systems and digital signal processing techniques
- Experience collaborating closely with software, electrical, mechanical, and manufacturing teams
Skills
- Experience with embedded systems and firmware development fundamentals
- Experience applying machine learning techniques to audio processing problems
- Background developing consumer electronics products
- Experience designing and supporting factory-level audio test systems and manufacturing validation processes
- Familiarity with voice interaction systems, beamforming, speech enhancement, or audio perception technologies
- Experience supporting products from prototype development through volume production
- Excellent communication and collaboration skills across multidisciplinary engineering teams
Compensation
- $173,861 - $240,000 + Equity
Benefits
- Comprehensive medical, dental, and vision coverage
- Generous paid time off, company holidays, and parental leave
- Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
- Commuter benefits (transit and parking)
- Short-term and long-term disability, and life insurance
- Employee Assistance Program (EAP) for mental health, financial, and personal support
- This team works across hardware, firmware, machine learning, software, industrial design, and manufacturing to deliver robust audio experiences that perform reliably inside homes and alongside people.
- You will design, integrate, and optimize microphone and speaker systems while partnering closely with software teams developing signal processing, machine learning, and perception capabilities.
Company info
- Deliver microphone and speaker systems that achieve robust performance across real-world acoustic environments
- Improve speech capture quality, localization accuracy, and overall audio reliability through iterative testing and optimization
- Successfully integrate audio hardware with signal processing, VAD, DOA, noise suppression, and machine learning pipelines
- Establish validation methodologies and performance metrics that support product readiness and production deployment
- Drive audio system performance improvements through field testing, data analysis, and cross-functional engineering collaboration
- Deep understanding of audio hardware design, acoustics, and electroacoustic system integration
- Strong hands-on engineering skills with the ability to prototype, test, debug, and validate hardware systems
- Ability to bridge hardware and software domains, collaborating effectively on signal processing and machine learning workflows
- Strong analytical mindset with experience interpreting performance data and driving design improvements
- We've been at this since 2014 and we're at the point where the hard problems are behind us and the hard work is in front of us.
