About the role

Key responsibilities & impact

Build coupled electromagnetic–plasma models of plasma chambers, antennas, matching networks, and enclosures.
Run frequency-domain, time-domain, and coupled-physics analyses with disciplined boundary conditions, meshing, and convergence checks.
Plan parameter sweeps and trade studies across geometry, materials, plasma properties, control schemes, and packaging constraints.
Screen concepts, quantify uncertainty, and build reusable, scriptable workflows for rapid iteration across product configurations and frequency bands.
Design experiments with RF, electrical, mechanical, and test engineers.
Compare predictions against bench measurements of S-parameters, radiation patterns, and plasma behavior.
Perform post-test analysis and root-cause investigations when measurements diverge from predictions.
Establish uncertainty bounds and traceable model records.
Deliver technical notes, figures, and design-review material informing architecture and prototype choices.
Own bounded analysis tasks while maintaining reproducible models, scripts, inputs, and results.
Communicate confidence, limitations, and next steps clearly.
