• Lead the application of acoustic engineering principles within robotics systems, supporting mechatronic and system‑level integration and mitigating vibration, motion‑induced noise, and environmental variability
• Perform acoustic simulations, modeling, and analysis to predict and optimize sound behavior
• Conduct lab and field testing, including frequency response, distortion, noise, and vibration analysis
• Develop and validate acoustic requirements, specifications, and test methodologies
• Analyze and troubleshoot sound quality issues, including noise, resonance, and interference
• Collaborate with mechanical, electrical, and DSP teams to integrate acoustic solutions
• Optimize audio performance through enclosure design, material selection, and tuning
• Mentor junior engineers and provide technical leadership within the team
• Document designs, test results, and engineering decisions

SKILLS AND REQUIREMENTS

• Strong understanding of acoustics principles (wave propagation, resonance, etc)
• Exposure to robotics systems, including mechatronics and system‑level integration, with experience applying acoustic engineering principles in dynamic environments and familiarity with challenges such as vibration, motion‑induced noise, and environmental variability
• Experience with acoustic measurement tools (e.g., microphones, analyzers, DAQ, anechoic chambers)
• Experience in a specific domain (consumer electronics, automotive audio, or pro audio systems)
• Familiarity with DSP (Digital Signal Processing) and audio tuning
• Knowledge of vibration and structural dynamics
• Experience with standards and compliance testing (e.g., ISO, IEC acoustic standards)
• Proficiency in simulation and modeling tools
• Hands‑on experience with sound testing and data analysis
• Advanced problem‑solving and analytical thinking
• Strong attention to detail and sound quality perception
• Ability to translate subjective feedback into measurable improvements
• Effective communication and cross‑functional collaboration

EDUCATION AND/OR EXPERIENCE

• Bachelor’s or Master’s degree in Acoustics, Audio Engineering, Mechanical Engineering, or related field
• 5–10+ years of experience in acoustic or audio engineering

PHYSICAL REQUIREMENTS

• Prolonged periods of sitting at a desk and working on a computer
• Must be able to lift 15 pounds at times
• Vision to read printed materials and a computer screen
• Hearing and speech to communicate
