Product Designer

Role Overview: We're looking for a passionate, creative, and detail-oriented Mechanical Designer to join the Nexstem team. You will work closely with our engineering, product, and NPD team to engineer the products that are not only cutting-edge in technology but also user-centric and aesthetically pleasing. Your primary focus will be on bringing the product functional and easily manufacturable.

Key Responsibilities

• Experience-Led Design: Craft intuitive physical interactions through refined features and touchpoints that enhance overall Design for Manufacturing and Assembly (DFMA), optimized for both mass production and prototyping phases.
• Concepts & Ideation: Generate innovative design concepts through advanced CAD modeling, exploring multiple design directions to solve complex mechanical and manufacturing challenges.
• 3D Modeling & Prototyping: Develop high-fidelity CAD models and functional physical prototypes for rapid iteration, with focus on mechanical fit, ergonomic skin contact, and precise sensor integration for optimal bio-signal capture.
• Mechanical Design & DFM: Engineer components, assemblies, and enclosures for manufacturability, with meticulous attention to tight tolerances critical for sensor accuracy, signal integrity, and user comfort.
• Materials & Process Engineering: Select and validate biocompatible, durable, and high-performance materials suitable for biosignal acquisition devices, including skin-safe plastics, flexible substrates, conductive materials, and moisture-resistant finishes.
• Creative Engineering Solutions: Develop innovative, scalable, and user-safe solutions to address unique design constraints posed by human-machine interfaces, including electrode placement, signal noise reduction, and wearable ergonomics.
• Cross-Functional Collaboration: Partner closely with neuroscientists, electrical engineers, industrial designers, firmware developers, and manufacturing teams to ensure seamless integration of mechanical, electronic, and user experience elements.
• Vendor & Production Liaison: Manage relationships with suppliers and contract manufacturers to coordinate prototyping, tooling, and scaling of components involving bio-acquisition hardware (e.g., dry electrodes, flex circuits, sensor housings, wearable straps).
• Technical Documentation: Create comprehensive engineering documentation including CAD drawings, BOMs, assembly instructions, and specifications that support regulatory compliance, design validation, and repeatable manufacturing of sensor-integrated wearables.
• Design Validation & Iteration: Conduct mechanical testing, design validation and drive continuous improvement based on real-world feedback.

• Education: Bachelor's or Master's degree in Mechanical Engineering, Product Design, Mechatronics, or a closely related field — or equivalent practical experience.
• Experience: Minimum 2 years of experience in developing physical products, with strong preference for work in bio-acquisition wearables, medical devices, or BCIs.
• Portfolio: A strong portfolio demonstrating end-to-end product development—including contributions to mechanically sound, sensor-integrated, and production-ready wearable solutions.
• Technical Tools: Expertise in PTC Creo, SolidWorks or Fusion 360 and proficiency with 3D prototyping techniques (e.g., 3D printing, CNC).
• Manufacturing Expertise: Proven experience with DFM/DFA, plastic injection molding, GFF molding, sheet metal, tolerancing, and assembly techniques suitable for precision fit around the human body.
• Team Collaboration: Strong history of working closely with engineering, neuroscience, and industrial design teams to translate design intent into manufacturable, high-performance products.
• Problem Solving: Methodical, iterative approach to design challenges—balancing user needs, technical feasibility, Manufacturability and regulatory considerations.
• Manufacturing Interface: Experience liaising with vendors and suppliers for wearable and sensor-integrated component production, managing risk and ensuring quality.
• Communication: Excellent skills in presenting design rationale, engineering trade-offs, and user research findings to multidisciplinary stakeholders.

• Biosignal Product Experience: Prior work in bio-acquisition products such as EEG, EMG, ECG, or other physiological monitoring devices is a significant advantage.
• Innovative Mindset: Passion for bringing life to cutting-edge, ergonomic, and reliable wearable technology inside the product that blends seamlessly into users' lives while delivering measurable impact.
