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. #J-18808-Ljbffr
