The ideal candidate is an experienced professional looking to apply their skills toward advancing NIRSense's transformational capabilities and who works well in a fast-paced, high-performance team.

Key Responsibilities:

• Lead mechanical design and development activities for NIRSense systems, wearable devices, and related hardware.
• Develop mechanical designs for rigid and flexible enclosures, molds, test fixtures, optical interfaces, and other product components using SolidWorks.
• Translate system and product requirements into mechanical designs that meet performance, usability, safety, and manufacturability requirements.
• Lead and support the development of prototypes and their progression toward production-ready designs.
• Identify, track, troubleshoot, and resolve mechanical and hardware design issues throughout the product development lifecycle.
• Develop and evaluate rapid prototypes, fixtures, molds, and prototype subassemblies to support product development and testing.
• Apply Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Test (DFT) principles to mechanical designs.
• Collaborate closely with electrical, firmware, software, scientific, manufacturing, and other engineering team members to ensure successful system integration.
• Support design verification and validation activities and ensure mechanical designs meet applicable product requirements.
• Develop and maintain mechanical design documentation, specifications, drawings, and other technical records.
• Support the transition of new designs from R&D and prototyping into repeatable manufacturing processes.
• Work within NIRSense's quality management system and applicable medical device regulatory requirements.
• Provide technical leadership, sound engineering judgment, and hands-on problem-solving across multiple development programs.

Minimum Qualifications:

• B.S. or M.S. in Mechanical Engineering, Biomedical Engineering, or a related field.
• Minimum of eight years of professional, post-graduate mechanical engineering experience, including substantial experience designing and developing medical devices and/or wearable products.
• Demonstrated experience leading mechanical design activities for complex products through multiple stages of the product development lifecycle.
• Advanced proficiency with SolidWorks , with demonstrated professional experience designing rigid and/or flexible enclosures, molds, test fixtures, optical interfaces, and mechanical assemblies.
• Strong knowledge of safety, performance, and regulatory compliance requirements for medical devices, including IEC 60601, ISO 10993, ISO 13485, ISO 14971, IEC 62366, and related FDA guidance.
• Demonstrated experience taking products from prototype through design verification, manufacturing readiness, and production scale-up.
• Experience with rapid prototyping processes, including creating fixtures, molds, and prototype subassemblies.
• Familiarity with Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Test (DFT) practices.
• Ability to independently identify and resolve complex mechanical design and system integration challenges.
• Strong technical communication and documentation skills with the ability to collaborate effectively across multidisciplinary engineering teams.

Preferred Qualifications:

• Experience designing waterproof and corrosion-resistant products.
• Design experience with systems interfacing with the human body.
• Experience developing wearable medical devices or other products intended for direct and prolonged contact with the human body.
• Experience working in a fast-paced R&D, new product introduction (NPI), or medical device development environment.
• Experience supporting products through design transfer and manufacturing scale-up.
