Principal Engineer, Acoustics

About the role

We are seeking a Principal Engineer, Acoustics to lead the design and development of high‑performance speaker drivers for consumer audio products. The role combines deep expertise in electro‑acoustic transducer design with end‑to‑end product lifecycle ownership, from concept through mass production.

Key responsibilities

• Lead the design of sub‑woofer, woofer, mid‑range, full‑range, and tweeter drivers, managing the full development process.
• Select and evaluate key driver materials (diaphragm, surround, spider, voice coil, adhesive, magnet) to meet performance and cost targets.
• Optimize driver parameters such as SPL, frequency response, distortion, excursion, power handling, thermal behavior, reliability, and cost.
• Collaborate with acoustics, mechanical, quality, and supplier teams to integrate drivers into complete acoustic systems.
• Work with suppliers to improve manufacturability, process capability, and yield.
• Support DFMEA, tolerance analysis, pilot builds, and transition to mass production.
• Lead root‑cause analysis and corrective actions for design, production, and field issues.
• Research and develop new driver technologies, materials, structures, and processes.
• Build proof‑of‑concept prototypes and document design rules and best practices.

Required profile

• Bachelor’s degree or higher in Acoustics, Mechanical Engineering, Materials Science, Electrical Engineering, Physics, or a related field.
• Extensive hands‑on experience in speaker driver design and development.
• Deep understanding of driver component materials and their impact on acoustic performance, reliability, and manufacturability.
• Strong knowledge of driver structure, motor design, suspension design, diaphragm behavior, and nonlinear performance.
• Proven track record delivering driver projects from concept to mass production.
• Familiarity with production processes, supplier management, and process control.
