Full Job Description
About ALSO. We’re ALSO, an electric mobility company originally conceived as a part of Rivian. We’re a passionate team of builders, dreamers, doers and innovators, focused on creating entirely new (not to mention, innovative and delightful) vertically integrated, small EVs designed to meet the global mobility challenges of today and tomorrow. Our mission is to inspire everyone to ride ALSO—replacing many local car, truck and SUV miles with ones on vehicles that are more affordable, more enjoyable and 10-50x more efficient. THE ROLE As an Embedded Validation & Tools Engineer - Audio & Wireless you will own validation for Bluetooth/BLE, Wi-Fi, wireless connectivity, media streaming, and audio subsystems for smart helmets. You’ll design and execute test plans that ensure high-quality audio (voice and media), reliable wireless connectivity, robust app integration, and excellent in-helmet user experience — across firmware, mobile apps, and cloud services. This role combines hands-on hardware and acoustic test work with automation, debugging, and cross-functional coordination with firmware, RF, DSP, and mobile teams. WHAT YOU WILL DO - Design and execute validation plans for Bluetooth Classic + BLE profiles (A2DP, AVRCP, HFP/HSP, BLE GATT), Wi-Fi streaming, and cross-stack interactions. - Validate media streaming quality (audio codecs, buffering, latency, jitter, packet loss recovery), multi-stream scenarios, and simultaneous voice/media use cases. - Test and tune audio processing: echo cancellation (AEC), noise reduction / suppression (NR), beamforming, automatic gain control (AGC), bass/treble tuning, and ANC/ANC-like features tailored for helmet acoustics. - Validate headset/headphone behaviors: microphone routing, sidetone, voice call quality (MOS scores), wind noise mitigation, and handset/helmet ergonomics that affect audio performance. - Develop and run automated test harnesses for firmware + mobile app integration (Android/iOS), including provisioning, reconnectio
