Job Description

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.
Skills & QualificationsCore Requirements

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.
Bonus Qualifications

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.
