Inspiren is hiring a Staff Audio Systems Engineer to lead the design and execution of digital audio processing systems and embedded software. You will drive innovation in 2-way communications, dictation, and high-fidelity audio, ensuring the integration of advanced technologies to deliver high-quality, low-latency solutions.
What You'll Do
- Oversee the end-to-end development of embedded audio systems, software, and firmware for new devices from concept to mass production release.
- Work closely with hardware engineers, embedded systems engineers, software developers, product managers, key stakeholders, and outsourced manufacturing partners to define system requirements and specifications.
- Stay current with industry trends and emerging technologies. Introduce new methodologies and technologies to enhance performance and meet design specifications.
- Conduct design reviews and both design and process Failure Mode Effect Analysis (FMEA). Partner with design and development partners to drive rigorous Design for Cost, supply chain, reliability, quality, and manufacturing methodologies.
- Provide technical guidance and mentorship, fostering a culture of excellence and innovation through continuous learning.
- Oversee the prototyping process, conduct testing, and verify audio systems performance and reliability against product requirements. Ensure all embedded software meets regulatory standards and industry best practices. Set quality and reliability specifications.
- Troubleshoot complex audio design issues and implement effective solutions in a timely manner.
What We're Looking For
- Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Audio Engineering, or a related engineering field.
- 10+ years of experience in embedded audio systems engineering including the successful launch and ongoing maintenance of multiple products.
- Proficiency in developing and tuning real-time algorithms for Beamforming, AEC and Noise Suppression using tools like MATLAB, Python, or Audio Weaver, and deploying them in C/C++ on embedded platforms.
- Expertise in modeling and simulating acoustic transducers (mics/ speakers) and enclosures using tools like COMSOL to optimize for frequency response and intelligibility in far-field environments.
- Deep expertise in low-latency full-duplex communications, including the design of echo cancellation paths and gain control strategies optimized for 'e-call' clarity.
- Ability to design and implement audio triggers and voice-activity detection (VAD) that transition devices from low-power passive states to active communication modes.
- Hands-on experience with ADC/DAC selection, high-SNR audio pipelines, and digital interfaces (I2S, PDM, TDM) for RTOS or Linux-based hardware.
- Extensive experience with audio test systems (Audio Precision, SoundCheck, HATS) to benchmark SNR, THD, and speech intelligibility (STI) across varied real-world clinical use cases.
- Knowledge of secure voice data handling, encryption for 2-way streams, and HIPAA-compliant audio pipelines.
- Excellent verbal and written communication skills, with the ability to convey complex ideas clearly.
- Comfortable working in a fast-paced, dynamic environment and adapting to changing priorities.
Nice to Have
- Start-up experience is a plus.
