Principal Embedded Software Engineer – Loudspeaker Expert & Audio DSP

About the Role

We’re looking for an experienced embedded software engineer to design and implement loudspeaker and haptics centric algorithms and the embedded firmware that powers next-generation audio products in consumer segment. You will own the full lifecycle—from modeling and algorithm development to fixed‑point implementation, optimization, verification, and productization on resource‑constrained MCUs/DSPs.

What You’ll Do

• Design loudspeaker/haptics centric algorithms including excursion/thermal limiting, power compression and adaptive limiters.
• Prototype in MATLAB/Python and translate to fixed‑point C/C++ with deterministic real‑time behavior.
• Model loudspeaker behavior and calibrate models with lab data for robust protection thresholds.
• Implement and optimize DSP components using SIMD, CMSIS‑DSP, or vendor libraries.
• Collaborate with hardware engineering teams on amplifier, thermal, and acoustic integration.
• Develop validation and verification tests, including acoustic performance testing.
• Drive production readiness including code quality, deterministic scheduling, and telemetry.

Minimum Qualifications

• BS/MS in EE/CE/CS or equivalent experience.
• 10+ years in embedded firmware and audio/DSP.
• Strong C/C++ skills for bare-metal and RTOS systems.
• Hands-on fixed‑point DSP implementation.
• Experience with MATLAB/Simulink and/or Python for modeling.
• Familiarity with I2S/TDM, audio codecs, and embedded toolchains.
• Experience with loudspeaker protection or real‑time audio control algorithms.

Preferred Qualifications

• Deep understanding of acoustics of loudspeakers and haptic transducers.
• Experience with speaker modeling including thermal/excursion models.
• Experience with acoustic measurements and tools such as Audio Precision and Klippel.
