Founding Hardware Lead

We're building an intimate device that responds in real time to a live AI-generated story and to her body: an app-connected, sensor-equipped vibrator synced to an interactive audio story that AI performs live. The device follows the story, and the story follows her body. Our first 1,000 pre-orders sold out, and we've raised a $1.5M pre-seed. All-woman founding team (CEO is an exited founder and HBS grad; CTO is a multi-time founder and MIT alum; COO/CPO helped lead Wattpad to a $650M exit).
This is employee #1.

You'll own hardware architecture, review and change our China partners' schematics and C/C++ BLE firmware (ESP32 / nRF), co-design the BLE protocol under tight latency budgets, integrate the IMU and body sensors (separating real body signals from the device's own vibration), and take us from prototype through EVT/DVT, certification and production, with trips to Shenzhen at key milestones.
You've shipped connected hardware end to end (consumer, wearable, medical or robotics), have 8+ years building hardware products with hands-on embedded work, and have been through at least one production ramp with a contract manufacturer. Bonus: haptics/motor control (ERM/LRA, PWM, waveform tuning), real-time systems, body-worn sensing, FCC/CE/Bluetooth SIG certification. Apply: email seema@experiencedevin.com with your resume or LinkedIn and a short note on one product you shipped: what you owned, the hardest hardware problem you solved, and how you knew it worked.
