Mechanical & Industrial Design Engineer (Wearables)

Job title : Mechanical & Industrial Design Engineer (Wearables)

Job type : Full-time (100%)

About the job:

The future of consumer electronics is here, and it’s all about non-invasive vital signs monitoring. At the forefront of this game-changing trend is PPG (photoplethysmography)—the cutting-edge technology enabling seamless monitoring of heart rate, blood oxygen levels, respiration rate, and even arterial blood pressure.

Senbiosys is proud to unveil the ultimate innovation in wearable tech: Velia smart ring, a groundbreaking device poised to revolutionize the longevity industry. Combining sleek design with unparalleled functionality, our smart ring integrates Senbiosys’s proprietary miniaturized PPG modules, delivering exceptional signal fidelity and ultra-low power consumption. This is more than just a product—it’s a leap generation ahead of the competition, achieved by overcoming extraordinary engineering challenges. The key to this breakthrough? A sophisticated, energy-efficient electrical system that powers everything.

To make this vision a reality, Senbiosys is searching for a talented Mechanical & Industrial Design Engineer (Wearables) to join our team. Are you ready to help us redefine the future of wearables? Let’s build the next generation of life-enhancing technology together.

• Conceptual Design & Prototyping
• Conduct design feasibility studies and develop product concepts using CAD and/or rapid prototyping tools
• Iterate on mechanical concepts for optimal ergonomics, aesthetics, and functionality
• Mechanical Engineering & 3D Modeling
• Produce detailed 3D models, drawings, and specifications for all mechanical parts using CAD software (e.g., SolidWorks, Creo, or Fusion 360)
• Perform simulations (FEA, thermal, stress, etc.) to ensure robustness, reliability, and safety
• Integration with Electronics
• Work closely with electrical engineers to co-design the mechanical housing of the smart ring, ensuring proper fit and protection of PCBs, sensors, and batteries
• Address challenges at the interface of electronics and mechanics (e.g., enclosure sealing, ESD protection, thermal management)
• Manufacturing & Production Readiness
• Assess and select appropriate materials for durability, cost-effectiveness, and comfort
• Collaborate with suppliers and contract manufacturers to develop tooling, refine designs for manufacturing (DFM), and implement quality controls
• Participate in design reviews, pilot runs, and final production validation
• Create and oversee, in collaboration with the quality and testing department, mechanical test plans (e.g., drop testing, water resistance/IP rating tests, wear & tear) to validate design
• Use test results to iterate and improve product integrity and user experience
• Cross-Functional Collaboration: work with operations, quality, marketing and R&D to align technical decisions with strategic goals and customer needs
• Present findings, design updates, and technical solutions to internal stakeholders

Your profile:

• Education & Experience

1) Master’s degree in mechanical engineering, Industrial Design, or related field,

2) 5+ years of hands-on experience in mechanical design and product development—preferably with experience in wearables or consumer electronics.

• Technical Expertise

1) Proven track record in end-to-end mechanical design: concept, 3D modeling, prototyping, testing, and release,

2) Familiarity with design for manufacturability (DFM) and knowledge of mass production processes (injection molding, CNC machining, metal stamping, etc.),

3) Knowledge of basic electronics fundamentals: PCB shapes/thickness, battery integration, and enclosure design.

• Software & Tools

1) Proficiency in at least one major CAD platform (SolidWorks, CATIA, CREO, Fusion 360, etc.),

2) Experience with simulation/analysis tools (FEA, thermal analysis) is a plus,

3) Knowledge of PLM or PDM systems is advantageous.

• Soft Skills

1) Excellent problem-solving and analytical skills with a demonstrated experience in working under tight time pressure,

2) Strong priority driven attitude,

3) Strong communication and collaboration skills; able to work across disciplines and with external suppliers,

4) Attention to detail and a passion for high-quality, user-centric design.

• Excellent organizational and project management skills

Nice-to-have:

• Experience with wearable devices (smart rings, watches, fitness trackers) or miniaturized product design
• Familiarity with materials specific to wearables (e.g., medical-grade silicones, stainless steel, titanium, or advanced polymers)
• Knowledge of environmental testing, IP ratings, and regulatory requirements (e.g., for consumer or medical wearables)
• Experience with PCB design (Altium) and PCB lab testing via electronic instruments
• Experience working in an agile or fast-paced startup environment

What you can expect:

• Opportunity to work on a ground-breaking wearable device with a passionate, cross-disciplinary team
• Employee-centered and flexible working environment
• Competitive salary and stock option plan participation
• Excellent team environment
