Sr. Embedded Validation & Tools Engineer - Audio & Wireless
- 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, reconnection, firmware upgrades, and profile/feature parity across platforms.
- Build and maintain hardware testbeds: HIL rigs, device farms, head & torso simulators (HATS), RF chambers or RF-shielded boxes, audio analyzers, and network emulators.
- Use RF and protocol sniffers (Ellisys/Frontline, Nordic/BlueZ tools) and network tools to diagnose Bluetooth/Wi-Fi connectivity, coexistence, throughput, and interference issues.
- Characterize and measure audio metrics (SNR, latency, frequency response), including subjective metrics (MOS, user studies)
- Reproduce and debug complex field issues: capture logs, packet traces, audio samples, and telemetry; perform root-cause analysis and drive fixes with firmware/DSP/RF teams.
- Create and maintain validation artifacts: test plans, automation scripts, acceptance criteria, failure-mode matrices, runbooks, and release readiness checklists.
- Bachelor’s degree in Electrical Engineering, Computer Science, Acoustics, or related field (or equivalent experience).
- 5+ years hands-on experience validating embedded audio and wireless systems (Bluetooth/BLE, Wi-Fi, or similar).
- Strong practical knowledge of Bluetooth profiles (A2DP, HFP, AVRCP), BLE GATT and provisioning flows, and Wi-Fi streaming behaviors.
- Experience with audio signal processing concepts and validation of AEC, noise reduction, AGC, echo control, and latency measurement.
- Proficiency with scripting/automation using Python (preferred) or shell; experience integrating tests into CI pipelines.
- Hands-on experience with audio measurement tools (audio analyzers, HATS/head simulators, APx or similar), RF/protocol sniffers, and network emulators (netem, WAN emulators).
- Strong debugging skills with embedded systems: serial/UART logs, JTAG/SWD, logic analyzers, firmware flashing, and log correlation across devices and mobile apps.
- Experience testing mobile app integrations for Android and iOS (using ADB, Xcode tools, instrumentation) and understanding of Bluetooth stacks on mobile platforms.
- Excellent problem solving and written/verbal communication; able to write clear test plans, bug reports, and postmortems.
- Background in consumer audio/headset validation, ANC, or helmet/automotive audio.
- Familiarity with audio codecs and streaming formats (SBC, AAC, aptX/aptX HD, LDAC, Opus) and voice codecs (CVSD, mSBC, Opus).
- Experience with DSP toolchains, MATLAB/Octave, or C/C++ signal processing code.
- Experience with cloud-connected telemetry, analytics stacks (Grafana, ELK), and deriving KPIs for fleet audio/connectivity quality.
- Experience performing field tests (on-road, varying environments) and designing safety-conscious test procedures for helmets.
- Robust health coverage — excellent health, dental, and vision insurance covered up to 100% by ALSO, with FSA & HSA options
- One Medical membership and dedicated insurance advocates
- Rich fertility and family-building benefits with Progyny
- Flexible time off
- 401(k) match
