Mechanical Design Engineer – Wearables

Introduction:

The work is at the forefront of new computing and human input technologies. To develop this hardware, we require a Mechanical Engineer with rapid prototyping, fixture development, and mechanical testing experience to contribute to EMG wristband program. We seek someone with the curiosity to research and investigate the design and functionality of a new class of wearable technology, with a focus on electromyography (EMG) signal quality and skin-electrode contact optimization. In this role, you will prototype and rework design concepts, generate fixture designs, make engineering drawings, execute testing, and analyze results. The role is 100% in-office in NYC.

Responsibilities:

• Research, design, develop, manufacture, and test wearable devices with a focus on rapid prototyping and device rework/repair
• Design mechanical test fixtures for both subsystem and system-level characterization and generate testing procedures
• Plan and execute Design of Experiments (DOEs) to evaluate key performance indicators for a wearable product
• Execute mechanical testing to characterize hardware using both standard and custom testing procedures
• Analyze test data against hardware specifications and contribute to the development of new KPI specs
• Assist on device failure analysis and conduct root cause investigations
• Provide 2D/3D CAD models of fixture and prototype concepts
• 100% in-office and lab work in NYC to include prototype assembly and rework, fixture development, and mechanical testing

Requirements:

Required Skills:

• Creativity, verbal and written communication skills, analytical and problem-solving ability
• Team player and detail oriented
• Ability to make sketches, engineering drawings and common computations
• Model, build, test, and refine prototypes and characterization test systems
• Previous experience with Siemens NX
• Experience with mechanical test and inspection equipment such as Instron, microscopes, OMM, temperature and humidity chambers
• Experience with prototyping equipment such as 3DP, laser cutter, heating elements, adhesives dispense/activation, soldering

Preferred Skills:

• Experience with wearable device assembly, including FPC (Flexible Printed Circuit) handling
• Experience working with load cells, tensiometers, or similar sensors for characterizing mechanical and biomechanical systems

Education/Experience:

• Bachelor''s degree in mechanical engineering or a related field required

Top 3 Must-Have Hard Skills:

1. Mechanical design for consumer electronics (NX, SolidWorks, or equivalent parametric CAD)
2. Hands-on prototyping and fabrication (3D printing, CNC, fixture design, bench-level assembly and debug)
3. DFM experience with injection molding and/or sheet metal (tolerance stack ups, GD&T, vendor drawing packages)

Good to Have Skills:

• Experience with wearable devices or miniaturized assemblies Familiarity with textile integration or flexible materials Comfort with test fixture design and bench-level reliability testing Working knowledge of thermal and structural FEA

Years of Experience Needed:

• At least 3 years of experience. Senior enough to own components independently but doesn''t need to be a tech lead.

Typical Day in the Role:

• Split between CAD work (design, drawing packages, tolerance analysis), hands-on prototyping (bench builds, debug, test fixture assembly), and cross-functional collaboration (EE, firmware, reliability, program). Expect to be in the lab 2-3 days a week working with physical hardware. No remote work

Resume Disqualifiers:

• No hands-on prototyping experience (CAD-only candidates won''t work here) No consumer electronics or miniaturized product experience Automotive/aerospace-only background without consumer HW crossover

How will performance be measured?:

• On-time delivery of component designs through build milestones (EVT, DVT, PVT). Quality of vendor drawing packages. Ability to independently own and drive component-level decisions. Responsiveness during factory builds.

Interview Process/Format:

• Portfolio review (show what you''ve designed and built), technical deep dive on a past project (design decisions, trade-offs, lessons learned), and a practical problem-solving exercise. Remote interviews are fine.
