Senior Mechanical Engineer Analyst

Axcelis Technologies•Beverly, MA

About The Position

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.

Requirements

MS or PhD in Mechanical Engineering, Physics, or related field
5–15+ years of industry experience in FEA or multiphysics modeling
Strong proficiency in Ansys (Mechanical / Workbench required; APDL experience preferred)
Proven ability to correlate simulation results with physical testing
Strong understanding of fundamental physics and practical engineering applications
Experience driving design decisions through analysis, not just supporting them
Excellent communication skills with ability to present to cross-functional teams and leadership
Demonstrated experience in one or more of the following: Nonlinear structural analysis, Thermal and thermomechanical modeling, Vibration or fatigue analysis and/or Coupled multiphysics simulations
