Sr Embedded Systems Engineer, Audio DSP, Fauna

About the role

We are seeking an Sr Embedded Engineer to lead the design and development of audio signal-processing subsystems for robots. You will own core audio algorithm design and implementation, requiring a deep mathematical foundation in signal processing and a strategic understanding of embedded systems.

Key job responsibilities

• Architect the audio processing pipeline at the embedded system level.
• Serve as the subject-matter expert on audio and signal-processing algorithms, providing technical guidance across electrical, mechanical, ID, and software teams
• Integrate and validate DSP algorithms on embedded, real-time platforms
• Research and specify electroacoustic components (microphones, speakers)
• Adapt and tune algorithms for varying hardware, software, and system constraints
• Collaborate cross-functionally with engineering, systems, software, and product management
• Manage and direct external audio and acoustics consultants, defining SOWs and integrating third-party acoustic design inputs into a program
• Partner with vendors on test and production activities

Basic Qualifications

• 5+ years of non-internship professional software development experience
• 5+ years of programming with at least one software programming language experience
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• Experience as a mentor, tech lead or leading an engineering team
• 7+ years developing DSP algorithms for embedded or real-time systems
• Proficiency in C/C++ and Python or MATLAB for signal-processing algorithm development
• Experience with microphone and speaker selection and characterization
• Deep signal-processing fundamentals: time/frequency duality, discrete-time signal processing, fixed- and floating-point implementation
• Hands-on prototype builds, hardware bring-up of audio subsystems, or design iteration cycles
• Practical knowledge of ML architecture design, data analysis, and training/evaluation methodologies for audio systems
• Experience with board bring-up, profiling, optimization, simulation, and manufacturing test fixture design, production test plans, yield analysis, and test-to-spec validation
• Experience debugging embedded systems and working with audio lab equipment (oscilloscopes, power analyzers, motor test benches)
• Proven ability to work effectively across cross-functional teams at all organizational levels
• Bachelor's degree in Electrical Engineering, Computer Engineering, Audio/Acoustics, or a related field

Preferred Qualifications

• 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
• Familiarity with mechanical integration of electroacoustic components
• Experience with signal detection and estimation, spatial audio, direction-of-arrival estimation, acoustic event detection, keyword spotting, or ML for embedded systems
