About Biostream.tech
We’re building a next‑generation wearable aimed at saving lives with embedded sensing and AI‑driven analytics. Small, focused team; high autonomy; fast decisions.
What you'll deliver in your first 90 days:
- Reproducible offline pipeline (Python/Matlab) for HR/RR/SpOâ‚‚ with motion handling; first pass at BP/PTT.
- Data capture stack: synchronized PPG + IMU logs, simple labeling tools, ground‑truth protocols.
- Firmware MVP on Cortex‑M/ESP32: sensor drivers, timestamping, buffering/streaming (BLE), low‑power plan.
- Baseline report: signal quality, latency, and energy budget with a roadmap to on‑device vitals.
Responsibilities:
- Design & validate biomedical pipelines (PPG motion artifact reduction, baseline drift, sensor fusion with IMU).
- Derive vitals (HR/RR/SpOâ‚‚) and explore BP via PTT; define calibration/quality metrics.
- Architect embedded firmware: drivers, DMA, double‑buffering, storage/streaming, clock sync, power modes.
- Prepare filters/models for TinyML / CMSIS‑DSP/NN; profile & optimize (fixed‑point where needed).
- Guide hardware choices (AFE, LEDs/PDs, IMUs, antenna constraints); support bring‑up and lab validation.
- Own data quality: capture protocols, ground‑truth pairing, QA dashboards, and acceptance criteria.
Must‑have experience:
- 5–8+ years across biosignal processing (PPG) and embedded firmware on Cortex‑M/ESP32.
- Shipped something that lived on a human body (medical / wellness / sports).
- Proven motion artifact handling in the wild; calibration experience.
- Strong Python + C/C++; comfort with profiling/optimization on MCU targets.
- Lab chops: scopes, logic analyzers, PCB bring‑up, AFE tuning, RF basics.
Nice to have:
- Edge ML (TinyML, CMSIS‑NN, TFL‑M), OTA, BLE/GATT design, antenna tuning, small‑batch manufacturing test.
Engagements and benefits:
- Contract: 3‑month SOW with clear milestones; option to convert to full‑time.
- Compensation: competitive day rate / salary + equity option on conversion.
- Tools, dev kits, and lab access supplied as needed.
- Remote (EU/UK) with regular lab days in London.
How to apply:
Send a short note with two shipped projects (links or brief) + CV/GitHub. Include availability and preferred day rate.
Seniority level: Mid‑Senior level. Employment type: Full‑time (after conversion), Contract initially. Job function: Engineering and Information Technology. Industries: Technology, Information and Internet.
