This position is being offered by EndoTheia, Inc., and not by Nissha Medical Technologies. While EndoTheia and Nissha Medical Technologies have entered into a strategic capital and business partnership to drive innovation in endoscopic device technologies, Nissha Medical Technologies holds a minority ownership interest. All employment-related matters—including hiring, onboarding, and management—pertaining to this role are solely under the purview of EndoTheia, Inc.

EndoTheia, a rapidly growing medical device startup developing flexible endoscopic devices to improve patient outcomes and empower physicians worldwide, is currently hiring for a Visualization Engineer to join their team in Nashville, TN.

This position will lead the development and integration of digital visualization and illumination systems for next-generation flexible endoscopic devices. This role will have a strong emphasis on CMOS image sensor integration, fiber bundle and LED illumination systems, and design-for-manufacture/assembly (DFMA) of millimeter-scale optical and electronic subassemblies.

Key Responsibilities

• Lead the integration of CMOS image sensors with custom and off-the-shelf imaging subsystems into novel medical devices.
• Design, prototype, and optimize fiber bundle and LED illumination assemblies for miniature visualization systems.
• Apply DFMA principles to the design of millimeter-scale optical and electronic components and subassemblies.
• Use PCB layout software to develop custom printed circuit boards for imaging and illumination systems.
• Use CAD to design assembly fixturing, precision enclosures, and integration hardware for sub-millimeter optical/electronic components.
• Collaborate with multidisciplinary teams (mechanical, clinical, regulatory, manufacturing) to ensure seamless system integration.
• Work with OEMs and suppliers to source, validate, and qualify imaging and illumination components.
• Prepare documentation (drawings, BOMs, assembly procedures) and contribute to design history files.
• Support design verification testing and performance characterization of prototypes.
• Participate in design reviews, risk analysis (FMEA), and design control activities.

Qualifications

• Bachelor’s or Master’s degree in Electrical, Optical, Biomedical, Mechatronics, or related Engineering field.
• 2+ years of engineering experience (medical devices or other highly regulated industry preferred).
• Hands-on experience with CMOS image sensors and/or fiber optic imaging systems.
• Familiarity with LED integration and optical coupling for small-form-factor devices.
• Experience applying DFMA at the millimeter scale for electronics and optical subsystems.
• Proficiency with PCB design software (KiCAD, Eagle, or Altium).
• Proficiency with CAD software (SolidWorks preferred).
• Strong problem-solving, organizational, and communication skills.

Desired Skills 

• Knowledge of ISO 13485, ISO 14971, and FDA QSR medical device design controls.
• Experience with IEC 60601 or other medical device safety standards.
• Familiarity with image signal processing and embedded system design.
• Comfort working in a fast-paced startup environment with evolving priorities.

Why Join Us

• Be Play a key role in developing cutting-edge visualization technology for flexible endoscopy.
• Collaborate directly with clinicians and engineers on impactful innovations.
• Competitive salary, benefits, and growth opportunities in a rapidly scaling company.

The pay range for this position is $90,000 - 140,000 Annual (USD). The successful candidate’s particular combination of knowledge, skills, and experience will inform their specific compensation.
