Responsibilities may include the following and other duties may be assigned.

• Lead the electrical design and development of advanced electrochemical glucose sensor systems, including circuitry, embedded systems, and signal processing algorithms.
• Define and execute verification and validation strategies for sensor electronics, ensuring compliance with relevant medical device standards (ISO 13485, IEC 60601, etc.).
• 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.

• 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.

• 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.

• 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.

• Bachelor's degree and minimum of 10 years of relevant experience.
• Or Master's degree with a minimum of 8 years related experience.
• Or PhD with 6 years relevant experience.
