Senior Sensor Development Engineer – Medical Device

Join our medical technology client as a Senior Sensor Development Engineer and lead the design and development of multi-analyte sensing electrodes for a next-generation continuous glucose, ketone, and lactate monitoring platform.

This role centers on creating stable, miniaturized enzymatic electrochemical sensors that maintain long-term activity under subcutaneous and in-vitro conditions. The position works closely with microfabrication, materials, biochemistry, and electronics teams to deliver a manufacturable, biocompatible, and high-performance sensor system.

This is an exciting role reporting directly into our client’s founder / CEO, and will have a significant impact on the company’s future success.

Requirements of the Senior Sensor Development Engineer:

• Advanced degree (M.Tech/PhD) in Biomedical Engineering, Materials Science, Chemical Engineering, Bioelectronics, or related field.

• 3–10 years of hands-on experience in biosensor or electrochemical sensor R&D.

• Expertise in electrode surface modification, enzyme immobilization methods, electrochemical characterization, and polymer coating technologies.

• Strong understanding of diffusion behavior, biofouling, tissue–sensor interfaces, and enzymatic redox systems.

• Experience with implantable or disposable biosensors; knowledge of microfabrication and flexible substrates.

• Familiarity with regulated environments (ISO 13485, FDA Class II, GLP).

• Experience with modeling tools such as COMSOL or ANSYS is a plus.

• Background working with Continuous Glucose Monitoring (CGM) technology is highly preferred.

Responsibilities of the Senior Sensor Development Engineer:

• Design and optimize electrode structures (Pt/Au/Carbon) for enzyme immobilization and efficient electron transfer.

• Develop strategies for enzyme stabilization and immobilization, including electropolymerization, redox polymer matrices, crosslinking, and hydrogel systems.

• Engineer multilayer coatings to control diffusion, enhance biocompatibility, and prevent enzyme loss.

• Integrate redox mediator systems enabling oxygen-independent electrochemistry.

• Perform electrochemical testing (chronoamperometry, CV, impedance) to assess performance and durability.

• Model diffusion behavior of glucose, oxygen, and mediators through membrane layers.

• Collaborate with materials and biochemistry teams to select polymers and optimize enzyme performance and shelf-life.

• Work with microfabrication and packaging groups to integrate the sensor wire into subcutaneous assemblies.

• Ensure all materials meet implantable biocompatibility and sterility standards.

• Lead accelerated aging and in-vitro stability studies to replicate long-term use.
