Job description

We are seeking an experienced Mechanical Product Design Engineer to design and develop innovative mechanical products from concept through prototype, with a strong focus on camera- and sensor-based systems.

The ideal candidate will have a strong product-based mechanical design background, preferably in consumer products, robotics, or medical devices. This role requires hands-on design expertise, strong problem-solving skills, and the ability to collaborate across mechanical, electrical, and software engineering teams.

Responsibilities

• Design and develop innovative mechanical products from initial concept through prototype, with a focus on camera- and sensor-based solutions.
• Create detailed 3D models and engineering drawings using SolidWorks.
• Apply thermal management principles and perform thermal simulations to ensure reliable operation of camera and sensor systems.
• Collaborate with electrical and software engineers to ensure seamless integration of mechanical, electrical, and software components.
• Develop, document, and manage mechanical design requirements.
• Conduct design validation activities, including testing, tolerance stack-ups, and design reviews.
• Perform root-cause analysis and structured problem-solving to resolve design and product issues.
• Apply Design for Manufacturability (DFM) and Design for Assembly (DFA) principles.
• Prepare and maintain engineering documentation, including drawings, specifications, and test reports.
• Work independently to drive projects forward, manage priorities, and meet project deadlines.

Essential Skills & Qualifications

• 5+ years of experience in mechanical product design.
• Strong mechanical engineering and product design background.
• Experience with product-based design, preferably consumer products, robotics, or medical devices.
• Proficiency in SolidWorks for 3D modeling, assemblies, and detailed mechanical drawings.
• Experience with thermal simulations and thermal management.
• Hands-on experience with tolerance stack-ups.
• Experience with testing, structured problem-solving, and root-cause analysis.
• Strong understanding of DFM/DFA and production design principles.
• Ability to work independently and take ownership of projects.

Preferred Skills

• Experience with ANSYS or similar simulation tools, particularly for thermal analysis.
• Familiarity with optics design and machine vision applications.
• Experience integrating mechanical, electrical, and software components.
• Background developing camera-focused or sensor-focused products.

Industry Background

Candidates with product development experience from consumer products, robotics, or medical device/surgical robotics are highly preferred.

Aerospace and automotive backgrounds are not preferred for this role.
