About the job
Join the Revolution at ALSO.
At ALSO, we are pioneers in the electric mobility space, initially conceptualized within Rivian. Our dedicated team comprises builders, innovators, and forward-thinkers committed to crafting revolutionary, vertically integrated small electric vehicles (EVs) that address the pressing mobility challenges of our time. Our goal is to motivate individuals to embrace the ALSO ride experience—transforming local car, truck, and SUV journeys into more affordable, enjoyable, and 10-50x efficient rides.
As a Senior Embedded Validation & Tools Engineer - Audio & Wireless, you will take ownership of validating Bluetooth/BLE, Wi-Fi, and audio subsystems for our smart helmet technology. Your role will involve designing and implementing test plans to ensure exceptional audio quality (both voice and media), dependable wireless connectivity, seamless app integration, and an outstanding user experience within the helmet environment—spanning firmware, mobile applications, and cloud services. This position combines hands-on hardware and acoustic testing with automation, debugging, and collaborative efforts across firmware, RF, DSP, and mobile teams.
Your Responsibilities
Develop and execute validation strategies for Bluetooth Classic and BLE profiles (A2DP, AVRCP, HFP/HSP, BLE GATT), Wi-Fi streaming, and cross-stack interactions.
Assess media streaming quality including audio codecs, buffering, latency, jitter, and packet loss recovery across multi-stream and simultaneous voice/media scenarios.
Test and optimize audio processing features such as echo cancellation (AEC), noise reduction/suppression (NR), beamforming, automatic gain control (AGC), and tailored ANC features for helmet acoustics.
Evaluate headset/headphone functionalities including microphone routing, sidetone, voice call quality (MOS scores), wind noise mitigation, and ergonomic factors that influence audio performance.
Create and implement automated testing frameworks for firmware and mobile application integration (Android/iOS), covering provisioning, reconnections, firmware updates, and feature compatibility across platforms.
Design and maintain hardware test environments including HIL rigs, device farms, head & torso simulators (HATS), RF chambers, audio analyzers, and network emulators.
Utilize RF and protocol sniffers (Ellisys/Frontline, Nordic/BlueZ tools) and networking tools to troubleshoot Bluetooth/Wi-Fi connectivity, interference, and throughput issues.
