Coil Design Engineer

Yank Technologies, Inc. is a wireless power startup in Brooklyn, New York. We develop long-range, high power wireless charging technology. Safe. Simple. No contact required. With patented coil and amplifier developments in resonant inductive technology, we provide a scalable solution for variable ranges of power and distances. We have multiple mobility, industrial, and space customers for a range of applications, such as wirelessly charging robotic vehicles and vehicle interior electronics.

The Coil Design Engineer will lead the design, analysis, and optimization of magnetic structures and resonant systems for near-field wireless power transfer applications. This role focuses on high-current, high-Q magnetic design rather than traditional RF antenna development. The ideal candidate has hands-on experience with power magnetics, including inductors, transformers, resonant structures, and wireless power systems operating in the low MHz range.

This position requires a practical engineer capable of bridging EM theory with real-world implementation. Responsibilities include high-Q coil development, magnetic modeling, parasitic and thermal analysis, coupling optimization, shielding strategies, and integration into compact electromechanical systems. Candidates should understand challenges associated with operating magnetic and power electronic systems at low MHz frequencies, including skin and proximity effects, EMI/EMC considerations, and material selection.

This role is highly technical and research-oriented, with opportunities to directly influence the next generation of wireless power technology. The Coil Design Engineer will contribute to advancing proprietary high-Q resonant coil architectures and help push the limits of efficiency, alignment tolerance, power density, and system scalability

Competitive compensation includes a base salary, healthcare benefits, and stock options in the company.

The primary responsibilities of the Coil Design Engineer are as follows:

• Design and optimize high-Q resonant coil systems for wireless power transfer applications operating in the low MHz range (6.78MHz and similar frequencies) 
• Develop custom magnetic structures including inductors, transformers, resonant coils, and shielding solutions for high power density systems 
• Perform electromagnetic analysis focused on coupling, parasitics, losses, thermal effects, and efficiency optimization under real-world operating conditions 
• Collaborate with power electronics engineers on system-level integration 
• Design, prototype, test, and validate magnetic components and wireless power assemblies in laboratory environments 
• Improve coil architectures with emphasis on quality factor (Q), alignment tolerance, manufacturability, thermal performance, and power transfer efficiency 
• Evaluate magnetic materials, conductor technologies, ferrite structures, and packaging approaches for compact wireless power systems 
• Support EMC/EMI analysis and mitigation strategies
• Work cross-functionally with mechanical, systems, and manufacturing teams to transition designs from prototype to production 

Qualifications Required

• Master’s Degree in Electrical Engineering 
• 3+ years of full-time experience in magnetics design, or wireless power applications 
• Strong experience modeling and validating magnetic components and resonant structures using tools such as Ansys Maxwell, CST, or equivalent 
• Hands-on experience designing, prototyping, testing, and manufacturing custom magnetic components 
• Experience designing planar magnetics, inductors, transformers, or high-Q coil systems 
• Understanding of skin effect, proximity effect, parasitic behavior, and thermal considerations in high-frequency magnetic systems 
• Hands-on laboratory debugging and hardware validation experience required 
• Excellent oral and written communication skills 
• US Citizen or US Permanent Resident 
• Ability to operate in a fast-paced environment, make effective and timely decisions, solve problems, and facilitate organizational and procedural changes 
• Passion for advancing next-generation wireless power technologies

Qualifications Preferred

• PhD in Electrical Engineering 
• Prior experience in wireless power transfer or resonant power conversion systems 
• Prior experience in automotive, industrial, or aerospace industries 
• Prior experience in high power density applications 
• Prior experience leading engineering development efforts or mentoring engineers 
• Prior startup experience
