Summary
👤
Senior🎓
Top SchoolJohn Maidens is a machine learning engineer specializing in biosignal analysis with 13 years of experience building regulated medical-device software and ML-driven sensing products. He has led end-to-end ML and DSP efforts—from real-time C DSP on mobile apps to cloud-deployed TensorFlow models—helping ship 510(k)-cleared heart sound and ECG SaMD at Eko and contributing to Apple’s optical heart rate sensing. More recently he led sleep-health ML at Eight Sleep and now develops models for a quantum magnetocardiography device at SandboxAQ, blending classical signal processing with cutting-edge sensor modalities. He holds a PhD in EECS from UC Berkeley and brings a rare combination of clinical study design, regulatory productization, and hands-on algorithm implementation. Notably, he secured over $3M in NIH SBIR funding as PI and authored peer-reviewed papers and patents on ML-based heart sound analysis. Based in Edmonton, he pairs deep technical rigor with cross-functional leadership in hardware-software-clinical teams.
