Essential Duties and Responsibilities:

• Contribute to the architecture and technical direction of magnetic bearing control electronics, from position sensors through power amplifiers and actuator interfaces
• Collaborate closely with controls, mechanical, and systems engineers to ensure control electronics are properly integrated with magnetic bearing dynamics, control algorithms, and mechanical constraints.
• Guide the development of firmware-hardware interfaces, including ADC/DAC selection, timing, synchronization, interrupt handling, and data paths critical to closed-loop control.
• Hands-on experience in designing analog and digital control circuits using Altium Designer.
• Lead or support trade studies evaluating control electronics topologies, sensor architectures, redundancy strategies, and fault-handling approaches.
• Participate in design of new magnetic bearing systems for new applications/machines. Specify requirements for magnetic bearing control hardware components such as DSP controller, PWM amplifiers, and power supplies; create system level wiring diagram.
• Provide engineering guidance to design reviews and troubleshooting support.
• Interface directly with customers, suppliers, and partners on control electronics topics, including technical reviews, requirements clarification, and issue resolution.
• Ensure control electronics designs meet applicable standards and program requirements (e.g., reliability, safety, environmental, and quality requirements).
• Actively monitor advancements in industry and academia related to magnetic bearing control, power electronics, digital control platforms, and sensing technologies, and translate relevant developments into practical design improvements.
• Support hands-on system bring-up and integration, including board-level debugging, signal integrity verification, timing validation, and coordination of electronics with mechanical and control subsystems.
• Lead hands-on troubleshooting during integration and test activities, diagnosing control electronics, sensor behavior, and digital timing issues using oscilloscopes, logic analyzers, and system-level test data.
• Prepare invention disclosures to protect intellectual property
• Architect, develop, and review digital control hardware utilizing CPLDs and FPGAs, including programming and verification using VHDL or equivalent hardware description languages, with attention to timing determinism, synchronization, and fault-handling behavior.

Education, Skills, and Experience:

• BSc + 5 years industry experience or MSc + 3 years industry experience in Electrical or Electronics Engineering with focus on digital electronics
• Background and experience with active magnetic bearings (AMB) and magnetic bearing controllers (MBC) preferred.
• Strong understanding of electronics and power electronics circuits operation and design.
• Strong skillset of debugging analog, digital, and power electronics circuits
• Experience in PWA board design in Altium
• Ability to debug, validate, and optimize control circuit designs from prototype through production.
• Experience with space vector, sinusoidal, and/or discontinuous PWM schemes.
• Strong knowledge of digital, analog and power electronic circuits design, test, and debugging
• Hands-on experience with power electronics test equipment such as scope, DC/AC electronics load, DC/AC power sources, current and voltage probes
• Strong circuit simulation experience (Matlab Simulink/PLECS/ LTSpice)
• Strong interpersonal, communication, presentation and technical writing skills
• Self-motivated, detail oriented, strong team player
• Strong problem-solving skills and the ability to think creatively
• Ability to drive projects to completion
• Ability to prepare test reports, conclude the outcome of test results, provide the next steps in test plan, and present it to management level
• Must be able to obtain a confidential security clearance within one year of start date

Intangibles Sought:
