Turner Imaging Systems develops innovative medical X-ray imaging devices that improve patient outcomes, expand healthcare access, and drive efficiency. We were awarded the Silver Medal by the 2022 Medical Design Excellence Awards and named Winner of the 2019 Utah Innovation Award for the Smart-C Portable X-ray Imaging System. See turnerxray.com and 3dteeth.com for examples of the amazing products developed by our team. Our company is rapidly growing with generous benefits and compensation.

We are growing our cross-functional engineering team to tackle our next big project, a portable whole-body x-ray imaging system for use in remote locations. Specifically, we need a versatile and motivated Electrical Engineer specializing in switching power supplies to design, build, and optimize high-voltage power supply systems. The ideal candidate will have a strong background in high frequency power electronics, with an emphasis on high-efficiency designs for medical, industrial, or commercial applications. If you share our values of passion, teamwork, customer commitment, integrity, and quality; and, you appreciate the opportunity to make an impact in the world by changing the way healthcare is delivered, this is the role for you.

Design and development knowledge and skills that include

Power Electronics Knowledge: MOSFETs, IGBTs, diodes, inductors, and DC-DC converters (buck, boost, buck-boost, SEPIC, flyback, forward, etc.)
Magnetics Design Experience: inductors and transformers for power supplies including knowledge of core materials, winding techniques, and loss calculation
Control Theory: control loop design (PID, voltage mode control, current mode control), feedback systems, loop stability, and compensation networks
Thermal Management: thermal analysis and design for effective heat dissipation, selection of heatsinks, cooling mechanisms, and layout optimization for thermal performance
PCB Layout for Power Systems: layout design for minimizing parasitics (such as inductance and resistance) and ensuring good current flow, grounding techniques (e.g., single-point vs. multi-point grounding), component placement to minimize EMI
EMI/EMC Considerations: Understanding EMI/EMC mitigation techniques (shielding, filtering, layout optimization)
Component Selection: based on efficiency, reliability, cost, size, and performance characteristics under various conditions
Simulation Tools: Proficient with simulation tools like SPICE, LTspice, or PLECS for circuit verification and familiarity with power supply design software, such as Texas Instruments’ WEBENCH or other vendor-specific tools
Efficiency Optimization: synchronous rectification, soft-switching techniques, and low-loss components for high efficiency across different load conditions
Power Supply Protection Design: overvoltage, overcurrent, thermal protection, soft start, inrush current limiting, and short-circuit protection circuits
Regulatory and Safety Standards: Familiarity with industry standards like IEC, UL, or ISO for isolation requirements and creepage and clearance
Testing: oscilloscopes, spectrum analyzers, load testers, and other lab equipment for testing; including thermal, EMI, and stress testing
Firmware Development: microcontroller-based power supply control and digital power supply algorithms (e.g., digital PID)
Analytical Skills: loss, efficiency, and other critical design calculations of transient and steady-state analysis of power circuits
Prototyping: Design, build, and test prototypes for rapid verification and validation of designs
