• Drive innovation through the evaluation and adoption of new materials, sensor architectures, and low-power electronics.
• Oversee design documentation, risk analysis, and failure mode analysis (FMEA) for sensor-related components.
• Interface with external partners, suppliers, and research organizations to advance sensor technology.
• Present technical findings and project updates to executive leadership and cross-functional stakeholders.

Design & Development:

• Architect electrical systems for continuous glucose monitors or other diagnostic platforms
• Develop signal conditioning circuits, analog front ends, and data acquisition systems for biosensor applications
• Design low-noise, high-precision potentiostat circuits and amperometric measurement systems
• Develop algorithms for signal processing, noise reduction, and biomarker detection
• Create electrical interfaces between biosensors and embedded systems
• Optimize sensor performance parameters including sensitivity, selectivity, and stability
• Drive innovation in sensor miniaturization, power optimization, and wireless connectivity

Technical Oversight:

• Collaborate with chemistry, mechanical, software, systems, and manufacturing teams to integrate sensor technology into commercial diabetes devices.
• Mentor and guide junior engineers and project teams in design best practices, troubleshooting, and root cause analysis.
• Review and approve electrical designs, test protocols, and validation procedures
• Lead design reviews and risk analysis activities

Regulatory & Quality:

• Ensure designs comply with FDA regulations (21 CFR Part 820), IEC 60601, and ISO 13485
• Support regulatory submissions including 510(k) and PMA applications
• Implement design controls and verification/validation protocols per medical device standards
• Partner with regulatory and quality teams to support submissions, audits, and compliance activities.

Required Knowledge and Experience:

Requires a Bachelor's degree and minimum of 10 years of relevant experience OR Master's degree with a minimum of 8 years relevant experience OR PhD with 6 years relevant experience.

Nice to Have:

• 5+ years of hands-on experience with electrochemical biosensing systems
