  • Collaborate on system architecture, including algorithms and tools, and oversee implementation.
  • Evaluate third-party audio technologies and keep abreast of industry developments.
  • Understand trade-offs among digital signal processing and machine-learning approaches and platforms for embedded solutions.
  • Work with the cross-functional team to innovate on audio solutions.
  • Provide factory testing and build support throughout the product development cycle.

Desired Qualifications

  • At least 8 years of experience in audio hardware development.
  • Proficiency in a high-level programming language such as MATLAB or Python.
  • Familiarity with human perception of sound.
  • Experience with psychoacoustic metrics and evaluation of speech quality and intelligibility.
  • Familiarity with audio rendering techniques and speaker technologies.
  • Experience in acoustics and consumer audio electrical engineering architecture.
  • Familiarity with audio algorithm development, machine-learning techniques, and/or neural network implementations.
  • An M.Sc. or Ph.D. in Electrical Engineering, Computer Science, Acoustics, or related disciplines.

About the Company

Sesame

Conveys real-time conversational voice interfaces

Sesame creates voice-based companions that blend into daily life by combining advanced software with lightweight wearables. Its Conversational Speech Model (CSM) understands context in real time and responds with fluid, human-like timing, including pauses, breaths, and emotion. The hardware pieces include sleek glasses that stream high-quality audio from the voice companion, creating an always-present, non-intrusive assistant. The system integrates software, machine learning, and hardware to offer a voice interface that feels more like chatting with a friend than issuing commands. Unlike many voice systems that sound robotic, Sesame focuses on natural, intuitive speech that fits into everyday activities. The company aims to turn voice into a rich, everyday interface and provide a personal, conversational companion that is easily integrated into daily life.
