YOUR DAY TO DAY:

We are actively seeking for a Mixed-Signal and High-Power Designer to join our CPI Power Electronics team. This hands-on role develops analog, digital, and power electronic circuitry for X-ray generators and solid-state RF generators and amplifiers. You will support circuit design, simulation, PCB development, prototype testing, and system integration from concept through production and sustaining support.

Working closely with Power, System, RF, Firmware, Software, Mechanical, Manufacturing, and Quality teams, you will develop accurate sensing, stable control, and fast protection circuits for demanding electrical environments. X-ray applications include platforms from 20 kW to 100 kW and beyond, while solid-state RF applications include power supplies, transistor bias, monitoring, sequencing, and protection electronics.

YOU WILL BE ACCOUNTABLE TO/FOR:

• Design analog and digital sensing and control circuits, including signal conditioning, analog-to-digital and digital-to-analog converters (ADCs/DACs), processor interfaces, calibration, and feedback control.

• Apply knowledge of digital signal processing (DSP), analysis, and DSP processor programming to support product development.

• Translate product requirements into hardware specifications and interface definitions, supporting system integration and verification with multidisciplinary teams.

• Design and develop power converters and associated circuitry for high-voltage X-ray generators.

• Design RF power-stage bias, sequencing, power monitoring, and fast protection circuits for electrical, thermal, and load-mismatch faults.

• Develop schematics, bills of materials, and PCB layouts, selecting components and addressing noise, thermal management, and EMI/EMC requirements.

• Perform circuit simulation, prototype bring-up, testing, and verification, comparing measured performance with calculations and simulation results.

• Support Design for Manufacturability and Testability (DFM/DFT), production transfer, alternate component qualification, and sustaining activities with Manufacturing and Quality.

• Conduct design risk assessments and implement interlocks and fail-safe protection.

• Maintain design records and support applicable electrical safety, EMC, and customer requirements.

Key Technical Responsibilities:

You will design and integrate technologies including:

• Mixed-signal sensing, signal conditioning, and data acquisition.

• Feedback control, calibration, and processor interfaces.

• Switching power conversion and high-voltage generator circuitry.

• Solid-state RF bias, sequencing, monitoring, and protection electronics.

• Embedded hardware interfaces, including SPI, I2C, UART, CAN, Ethernet, and isolated communications, as appropriate to the product.

• Semiconductor protection, noise control, thermal management, and EMI/EMC mitigation.

YOU ARE THE RIGHT PERSON FOR THIS JOB IF YOU HAVE/ARE:

• A bachelor’s degree in Electrical Engineering, Electronics Engineering, Physics, Systems Engineering, or a related technical discipline.

• At least four years of experience developing electronic systems, including at least three years of hands-on mixed-signal and power-electronics design.

• Demonstrated responsibility for circuit design, simulation, schematic capture, PCB reviews, prototype bring-up, verification, and production release.

• Experience integrating control electronics with high-power converters, high-voltage equipment, or solid-state RF power systems in a multidisciplinary development environment.

• Strong understanding of analog and digital circuit design, data acquisition, feedback control, switching power conversion, semiconductor protection, and EMI/EMC mitigation.

• Proficiency with Altium Designer or equivalent ECAD tools and SPICE-based circuit simulation, with the ability to correlate calculations and simulations with measured results.

• Experience with embedded hardware interfaces and communications relevant to the product.

• Practical knowledge of laboratory measurements, electrical safety, systematic troubleshooting, root-cause analysis, and technical documentation.

• Experience with X-ray generators, tube interfaces, radiography, fluoroscopy, CT, or industrial imaging systems is preferred.

• Experience with solid-state RF generators or amplifiers, GaN or LDMOS bias and protection, RF power detectors, and load-mismatch behaviour is preferred.

• Experience with SiC or GaN power conversion, power converter topologies, magnetics, digital control, or MATLAB/Simulink is preferred.

• Familiarity with regulated product development, requirements management, Azure DevOps or comparable tools, automated test development, and mentoring technical team members is preferred.
