About The Position

Sapphire is looking for a rotordynamics and controls engineer to join the Magnetic Bearing Technology group. This role involves a mix of analysis, testing, software development, and field support for magnetic bearing systems.

Requirements

Masters or PhD in ME or EE required.
Minimum of 3 years related experience in dynamics and/or controls required.
Knowledge of dynamics or controls analysis, especially for rotating machinery (rotordynamics) required.

Nice To Haves

Understanding of control algorithm design for closed-loop control systems a plus.
Knowledge of data acquisition systems and instrumentation a plus.
Familiarity with magnetic bearing controller hardware components a plus.
Understanding of magnetic bearing principles and applications a plus.
Experience with machine-level magnetic bearing system testing and troubleshooting a plus.

Responsibilities

Perform rotordynamic modelling in tools such as XLROTOR and Matlab suite of rotordynamics and controls analysis tools.
Use Matlab to analyze stability and performance of magnetic bearing control system loops, and to design compensators that ensure robust performance.
Conduct final tuning on control algorithms based on transfer function measurement, sensor signal time history, and power spectrum in the shop and in the field.
Participate in design of new magnetic bearing systems for new applications/machines.
Develop or modify Labview-based magnetic bearing graphic user interface (GUI).
Develop and conduct training sessions with field service engineers, test engineers, and technicians.
Interface with internal and external customers, as required, for field service, applications, and product support.
