Job summary

Healing Innovations in Nashville is seeking a hands-on mechanical engineer to design, prototype, verify, and pilot fabricate systems for a robotic rehabilitation medical device transitioning from R&D into production.

You will collaborate with controls, electrical, and production teams to deliver hardware that meets clinical, safety, and manufacturing requirements, and you will document engineering deliverables in a structured development environment.

Qualifications

• Bachelor’s degree in Mechanical Engineering or closely related field.
• Proficiency in a parametric 3D CAD tool (Onshape preferred; SolidWorks/CATIA acceptable).
• Hands-on prototyping and hardware build experience; comfortable testing hardware.

Responsibilities

• Develop and iterate mechanical concepts, mechanisms, and subsystems across product generations.
• Create CAD models, manufacturing drawings, and engineering documentation for prototype and pilot components.
• Build and evaluate prototypes at subsystem and system levels; execute mechanical verification test protocols and document results.
• Prepare and maintain pilot fabrication documentation: assembly instructions, BOMs, and process documentation.
• Support user testing and pilot study activities, including test article preparation and follow-up design analysis.
• Implement design improvements based on user, clinician, and internal feedback across prototype and pilot phases.
• Contribute to design-for-manufacturing and assembly (DFM/DFMA) optimization during commercialization preparation.
• Maintain assigned subsystem documentation and collaborate with controls/electrical engineering on system integration.
• Support pilot device installations and clinical training sessions; travel <10%.

Job description

Role Overview

We are seeking a hands-on and detail-oriented mechanical engineer to contribute to the design, prototyping, verification, and pilot fabrication of systems and subsystems for a robotic rehabilitation medical device currently transitioning from active R&D into pilot production and commercialization. This role works closely with controls, electrical, and production teams to deliver hardware that meets clinical, safety, and manufacturing requirements. The ideal candidate has a strong foundation in mechanism design and parametric CAD, experience building and testing hardware beyond just designing it, and the ability to manage subsystem documentation and engineering deliverables in a structured development environment.

Key Responsibilities

• Develop and iterate mechanical concepts, mechanisms, and subsystems across product generations.
• Create CAD models, manufacturing drawings, and engineering documentation for prototype and pilot components.
• Build and evaluate prototypes at the subsystem and system levels; execute mechanical verification test protocols and document results.
• Prepare and maintain pilot fabrication documentation: assembly instructions, BOMs, and process documentation.
• Support user testing and pilot study activities, including test article preparation and follow-up design analysis.
• Implement design improvements based on user, clinician, and internal feedback across prototype and pilot phases.
• Contribute to design-for-manufacturing and assembly (DFM/DFMA) optimization during commercialization preparation.
• Maintain assigned subsystem documentation and collaborate with controls and electrical engineering on system-level integration.
• Support pilot device installations and clinical training sessions; occasional travel required (<10%).

Candidate Profile

• Self-starter: tackles complex problems without hand-holding.
• Comfortable with complexity: large, messy projects don’t rattle you.
• High drive: moves fast and shows real progress every week.
• Team player: shares knowledge, listens, and helps others win.
• Quality-focused: won’t call it done until the work is rock-solid.
• Learns on the fly: masters new tools, standards, and protocols quickly.
• Mission-minded: motivated by restoring mobility for patients.

Basic Qualifications

• Bachelor’s degree in Mechanical Engineering or a closely related field.
• Demonstrated proficiency in a parametric 3D CAD tool (Onshape preferred; SolidWorks, CATIA, or similar acceptable).
• Experience with mechanism design and analysis (linkages, actuated systems, or similar).
• Hands-on prototyping and hardware build experience; comfortable building and testing, not only designing.
• 0-2 years of professional experience in a mechanical engineering role; recent graduates with strong internship or project portfolios encouraged to apply.
• Authorization to work in the USA (we do not sponsor H1B).
• Fluent in English.

Preferred Qualifications

• Familiarity with DFM/DFMA principles and manufacturing constraint awareness.
• Experience creating engineering documentation (detailed drawings, BOMs, assembly instructions).
• Exposure to a regulated development environment (medical device, aerospace, or similar).
• Experience with Onshape specifically.

About Healing Innovations

Healing Innovations is a Nashville-based medical-technology company building robotic neuro-rehabilitation systems that help people recover mobility after neurological injury.
