Product Developer/Hardware Specialist

Job Description ​We are looking for an experienced, forward-thinking Product Developer / Hardware Engineer to help lead the physical design, component sourcing, and prototyping phase for The Vortex Ring—a cutting-edge, biometric-integrated wearable tech project. ​This isn't just another standard fitness tracker. The Vortex Ring is built for sophisticated, high-integrity data tracking, blending advanced biometric sensors with a sleek, premium aesthetic. We need someone who can bridge the gap between complex engineering and elegant, ergonomic industrial design. ​Key Responsibilities ​Component Architecture: Research, select, and source ultra-compact hardware components (microcontrollers, BLE modules, biometric sensors, and specialized power management systems) that fit a ring form factor. ​Prototyping & Iteration: Develop functional schematic designs, PCB layouts, and 3D-printed enclosure models for rapid prototyping. ​DFM (Design for Manufacturing): Optimize the mechanical and electrical layout to ensure the product can transition smoothly from prototype to scalable factory production. ​Vendor & Supply Chain Coordination: Interface with component suppliers and manufacturing partners to oversee initial sample runs. ​Required Skills & Experience ​Proven track record in wearable technology product development (smart rings, smartwatches, or ultra-compact IoT devices). ​Deep expertise in PCB design and layout for space-constrained electronics (Altium, Eagle, or KiCad). ​Strong experience with biometric sensor integration (such as PPG for heart rate, skin temperature sensors, or galvanic skin response). ​Proficiency in 3D CAD modeling for product enclosures (SolidWorks, Fusion 360) with a keen eye for ergonomic, high-end industrial design. ​Experience navigating the manufacturing landscape, including component sourcing and DFM constraints. ​Project Details & Logistics ​Project Type: Contract / Milestone-based (with potential for long-term ongoing collaboration). ​Scope: Initial phase focuses on hardware architecture review, sensor selection optimization, and layout strategy for the next prototype iteration. ​Location: Remote friendly. ​If you have a passion for pushing the boundaries of what wearable tech can do and want to build a product designed to make a real impact, please apply with a brief overview of your relevant hardware experience and portfolio examples of compact wearables you’ve brought to life
