Electro Magnetic Engineer

Job Description

Brooks Automation is developing next-generation precision motion technologies for semiconductor automation. We are seeking a highly capable Senior Electromagnetic Systems Engineer to design and validate advanced electromagnetic actuation systems used in magnetic levitation, propulsion, and precision motion control applications.

This role is ideal for an engineer who enjoys solving challenging multidisciplinary problems and can bridge electromagnetic theory, simulation, hardware design, and experimental validation. The successful candidate will be responsible for developing electromagnetic solutions that achieve high force density, precise six-degree-of-freedom (6DOF) motion control, low force ripple, and high efficiency while meeting demanding performance, reliability, and manufacturability requirements.

The position combines analytical work, finite element modeling, laboratory experimentation, and close collaboration with controls, mechanical, electrical, and manufacturing engineers.

Key Responsibilities

Electromagnetic System Design

Design and optimize electromagnetic actuators, magnetic circuits, coils, and permanent magnet assemblies for precision motion systems.
Develop magnetic architectures including Halbach arrays, linear motors, synchronous electromagnetic actuators, and other advanced motion technologies.
Analyze and optimize force generation, levitation performance, propulsion efficiency, and actuator stiffness.
Evaluate magnet material options, including rare-earth and non-rare-earth technologies.
Design electromagnetic systems that support precision multi-axis motion and closed-loop control.

Modeling & Simulation

Develop and validate electromagnetic finite element models using industry-standard tools such as Ansys Maxwell, JMAG, COMSOL, Altair Flux, or equivalent.
Perform magnetic, thermal, and multiphysics simulations.
Predict and minimize force ripple, cogging effects, power losses, magnetic saturation, eddy currents, and thermal constraints.
Correlate simulation results with laboratory data and continuously improve model accuracy.

Thermal & Electrical Analysis

Design and evaluate coil architectures, current requirements, voltage requirements, and overall electrical performance.
Conduct thermal analyses to establish operating limits, duty cycles, cooling requirements, and long-term reliability.
Collaborate with power electronics engineers to define current drivers, sensing requirements, and system architectures.

Motion Control Support

Develop force models and commutation strategies for electromagnetic actuators.
Support controls engineers through creation of actuator models, force maps, and system characterization data.
Analyze force and torque generation mechanisms and their impact on precision motion performance.

Experimental Validation

Design and build laboratory test fixtures and prototypes.
Plan and execute engineering experiments to validate electromagnetic, thermal, and dynamic performance.
Collect, analyze, and interpret test data.
Generate formal test reports, design verification documentation, and technical recommendations.
Drive design improvements using a data‑driven engineering approach.

Cross‑Functional Collaboration

Work closely with electrical, mechanical, controls, manufacturing, and reliability engineering teams.
Participate in design reviews and technical problem‑solving activities.
Contribute to innovation initiatives, invention disclosures, and intellectual property development.
