Engineering

iPolish, Inc. is a Central Florida digital beauty technology company pioneering electrophoretic display (EPD)-based color-changing cosmetic products, including digitally programmable press-on nails and the Magic Wand handheld programming device. We operate at the intersection of advanced materials science, consumer electronics, and fashion-tech, with manufacturing partners in China, Taiwan, USA, Japan and Mexico and a product roadmap targeting simultaneous launch across North American, European, and Asia-Pacific markets.

We are seeking an experienced Senior Electrical & Hardware Engineer to lead the design, prototyping, and bring-to-market of mixed-signal embedded systems at the core of the iPolish® product platform. This role is central to the continued development of the Magic Wand device — a compact, battery-powered wireless EPD programmer — as well as next-generation iPolish press on nail display hardware. You will work directly with the founders across the full hardware development lifecycle, from schematic capture through DFM, multi-market regulatory certification, and volume manufacturing.

This role carries significant international compliance coordination responsibility: iPolish products are wireless, battery-powered, and skin-adjacent, and the successful candidate will help drive certification and market-access programs across the US, Canada, UK, EU, and Asia-Pacific.

• Own schematic capture and PCB layout for compact, battery-powered consumer electronics products, including the Magic Wand (ESP
  32-C6-class Wi-Fi/BLE SoC, LiPo power system, high-voltage EPD source/gate drivers)
• Design and validate low-voltage analog/mixed-signal circuits, including power-path management (ideal-diode ORing, PFET mux, LDOs), high-voltage EPD driver rails (±30 V class VGH/VGL supplies), and USB-C charging topologies
• Perform component voltage-rating and derating audits, tolerance analysis, and FMEA; maintain design verification test plans for reliability and safety compliance
• Lead design-for-manufacturing (DFM) reviews and coordinate with overseas CM partners (China, Taiwan, Mexico) on PCB fabrication, panelization, SMT assembly, and functional test infrastructure — including bed-of-nails / spring-pin programming and test fixtures
• Develop and maintain full Bills of Materials (BOM) and CPL/placement files with preferred and alternate sourcing, Digi Key / LCSC / Mouser cross-references, and formal component change documentation (ECOs, CCNs)
• Coordinate international wireless and product-safety certification programs end-to-end: FCC and ISED (Canada), CE RED and UKCA, SAR testing, MIC/Giteki (Japan), SRRC (China), and emerging EU radio-equipment cybersecurity requirements (EN 18031 series); manage test-house relationships, technical files, and Declarations of Conformity
• Support battery and product safety compliance, including UN 38.3 transport testing, pack-level certification (UL 2054 / IEC 62133 class), and safety-relevant component selection (e.g., glow-wire-compliant connectors)
• Track evolving market-access requirements (EU GPSR, EU Battery Regulation labeling and marking phases, RoHS/REACH) and translate them into actionable design and documentation changes
• Collaborate on firmware-hardware integration with embedded software developers; review strapping-pin and boot configurations, bring-up procedures, and factory calibration and programming flows
• Contribute to IP documentation and patent prosecution support as needed, working with outside counsel and Rocket Patent LLC
• Manage hardware project timelines, milestone tracking, and cross-functional dependencies across engineering, operations, and external vendors; maintain schedules from prototype build through production release
• Author and maintain technical project documentation including design history files, ECO logs, component change notices, and design review packages

• B.S. or M.S. in Electrical Engineering, Computer Engineering, or equivalent
• 5+ years of hands-on hardware product development experience with consumer electronics or IoT devices
• Proficiency in schematic capture and PCB layout;
  Fusion 360 Electronics / EAGLE experience strongly preferred (Altium or KiCad acceptable with willingness to work in the company toolchain)
• Demonstrated experience with ESP
  32 or equivalent Wi-Fi/BLE SoC families; familiarity with Nordic nRF
  52-class BLE SoCs a plus
• Experience with battery-powered products:
  LiPo charging/protection, power-path management, thermal and safety design
• Solid understanding of EMC principles and direct experience supporting FCC/CE certification campaigns, including pre-scan, test-house liaison, and remediation
• Working knowledge of international market-access frameworks for wireless consumer products (radio, safety, battery, and labeling…
