Senior Mechanical Engineer Analyst

About the role

Axcelis is seeking an experienced Senior Mechanical Analyst to lead advanced multiphysics modeling for semiconductor capital equipment. This role focuses on solving complex, real-world engineering problems in high-vacuum, thermally sensitive, and precision mechanical systems, with a direct impact on product performance, reliability, and cost. The ideal candidate brings strong industry experience, applies first-principles physics to practical design challenges, and uses simulation to drive critical engineering decisions.

Responsibilities

• Lead advanced FEA and multiphysics simulations to support design, optimization, and troubleshooting of complex systems.
• Own analysis activities end-to-end, including model setup, validation, and design recommendations.
• Perform structural (linear and nonlinear), thermal, vibration, and coupled multiphysics analyses.
• Translate simulation results into actionable design improvements that enhance performance and reliability.
• Partner with engineering and process teams to define modeling approaches and validation strategies.
• Design and support test plans to correlate models with experimental data.
• Influence product architecture and subsystem design through physics-based insights.
