Job description

Electrical Engineer – Wearable Biosensing

We are seeking an Electrical Engineer to help design, develop, and validate the electrical systems for a wearable medical device platform. You will work closely with cross‑functional partners across mechanical engineering, firmware, and electrochemistry to bring complex biosensing hardware from prototype to production.

This role is ideal for a self‑motivated, hands‑on engineer who enjoys early‑stage product development and wants meaningful ownership over real‑world hardware systems. You will lead day‑to‑day electrical prototyping and testing, with guidance from a senior electrical engineer, while ensuring systems meet performance, reliability, and safety standards.

Responsibilities

• Serve as the electrical subject matter expert (SME) across R&D initiatives
• Design, prototype, and test PCB layouts, analog and digital circuits, and power management systems for wearable biosensors
• Develop electrical architectures integrating sensors, wireless communication, and embedded systems
• Collaborate closely with mechanical engineering, firmware, and electrochemistry teams
• Support compliance with medical device standards (IEC 60601, IEC 62304, ISO 13485) and risk management processes
• Conduct failure mode and effects analysis (FMEA) to improve system reliability and manufacturability
• Execute test plans related to EMC/ESD compliance, signal integrity, and power efficiency
• Support transition from R&D to pilot‑scale and high‑volume manufacturing, including DFM and DFT
• Troubleshoot electrical issues in released products and support sustaining engineering efforts
• Maintain detailed engineering documentation including schematics, BOMs, and validation reports

Qualifications

• Required: Bachelor’s degree in Electrical Engineering, Electronics Engineering, or a related field
• 5+ years of experience designing electrical hardware products
• Strong PCB design and layout experience (Altium, OrCAD, Eagle, or similar)
• Solid grounding in analog/digital circuit design, power management, signal processing, and embedded systems
• Hands‑on experience with wireless communication protocols (BLE, Wi‑Fi, NFC, RF)
• Proficiency with hardware debugging tools (oscilloscopes, logic analyzers, electrical test equipment)
• Familiarity with medical device development processes and regulatory standards (21 CFR 820, ISO 13485, IEC 60601) is a strong plus
• Experience taking products from concept through production
• Strong problem‑solving skills and comfort working in a fast‑paced, multidisciplinary environment
• Clear written and verbal communication skills
• Preferred Skills: Master’s degree preferred
• Experience with flexible electronics or wearable form factors
