DUTIES& RESPONSIBILITIES:

  • Analyze, design, develop, support and troubleshoot control algorithms for servo systems, environmental control systems and power electronics for semiconductor packaging equipment.
  • Will be responsible for analog, digital, S-domain and Z-domain controller design with appropriate analysis, modeling and simulation.
  • Practical understanding of system identification using time domain analysis and understands how to produce and use  Bode and Nichols plots.
  • Multidisciplinary responsibilities include plant characterization of electronics, electromagnetic devices, gear trains, and mechanical structures.
  • Strong Digital signal processing with practical application such as Digital filtering including the understanding of different types of filters FIR, IIR, Butterworth, etc.
  • Responsibilities also include, with the support of the engineering team, requirements definition for individual servo components (electric motors – power, speed, torque; gear trains – reduction ratios, back-lash; feedback devices – resolution, accuracy, noise,…etc). This includes supporting in-house design or locating off-the-shelf vendor components and/or helping vendors develop components to meet requirements.
  • Responsible for all documentation necessary for sound engineering development (lab notebooks, test reports, trade studies, block diagrams, hand sketches, theory of operations, white papers, etc).
  • Required to travel to customer facilities to provide engineering support and/or customer evaluation as needed.
  • Performs other duties as assigned.
  • C programming experience.
  • Responsibilities also include electrical, mechanical and software test and/or test support in the lab and in the field to verify system performance and troubleshoot problems. This includes assembly, test set-up and test data collection.

  • Expected to work in a safe manner in accordance with established operating procedures and practices.

JOB QUALIFICATIONS:

  • An electrical engineering PHD degree or master’s degree from an accredited institution and three or more years of experience.  Substitution of equivalent engineering experience may be discussed in lieu of education.
  • Experience in closed loop control analysis and design including S-domain and Z-domain controllers.
  • Must have analytical and practical knowledge of electro-magnetic and mechanical devices.
  • Must have some hands on hardware experience.
  • Experience with analysis in MATLAB and/or other system modeling tools.
  • Experience with system verification test methods (phase-gain stability determination using small signal swept sine or random noise, and large signal transient disturbances).

DESIRABLE QUALIFICATIONS:

  • Experience with state space approaches to analyzing controls problems as well as classical frequency domain methods.
  • Familiarity with Linear Quadratic Regulator and Estimator approaches to quasi optimal steady state and non-steady state controls solutions.
  • Familiarity with simulation techniques including the Runge-Kutta methods of non-linear simulations.
  • Familiarity with assembly programming.
  • Self-motivated. Completes tasks with little supervision.
  • Can-do attitude that doesn’t shy away from new challenges, making adjustments and solving problems real time.
  • Kulicke & Soffa is an Equal Opportunity/Affirmative Action employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, gender expression and gender identity, national origin, disability, or protected veteran status.
