Senior Mechanical Engineer

Axcelis Technologies•Beverly, MA

31d•$121,050 - $181,575

About The Position

Axcelis is seeking a Senior Mechanical Engineer to design and deliver critical hardware for next-generation semiconductor capital equipment. In this role, you will own subsystem designs and drive end-to-end engineering execution, developing solutions that directly impact tool performance, wafer-level outcomes, and customer productivity. You will work on tightly integrated electromechanical systems where mechanical design directly impacts system performance, throughput, and reliability, partnering with cross-functional teams to deliver differentiated technology to leading semiconductor manufacturers.

Requirements

BS in Mechanical Engineering required (MS preferred)
8–12+ years of experience designing complex electromechanical systems
Demonstrated ownership of subsystems or major components in a product development environment
Strong proficiency in 3D CAD and PLM tools (Creo/Windchill or equivalent)
Solid experience with mechanism design, tolerance analysis, and engineering fundamentals
Working knowledge of FEA and analytical methods for design validation (Ansys preferred)
Ability to independently drive design work while collaborating across teams
Strong communication and problem-solving skills

Nice To Haves

Semiconductor capital equipment or vacuum system design
Precision motion, robotics, wafer handling, or automation systems
Experience in new product development (NPI) environments with fast iteration cycles
Exposure to high-reliability systems and customer-driven requirements
Familiarity with SEMI standards and cleanroom design considerations

Responsibilities

Own end-to-end design, development, and validation of mechanical subsystems
Translate system and process requirements into robust hardware solutions
Directly influence performance, yield, and reliability at the system and customer level
Operate as a system thinker, connecting mechanical design decisions to overall tool behavior
Design and develop mechanical subsystems and assemblies for advanced semiconductor equipment
Own engineering execution from concept through validation and release, delivering complete solutions to technical challenges
Translate system-level and process requirements into clear mechanical design requirements
Perform design tradeoffs and risk assessments, selecting optimal solutions based on performance, cost, and schedule
Conduct engineering analyses (tolerance, thermal, structural), validating designs through both simulation and first-principles calculations
Plan and execute structured testing and validation, including prototype builds and experimental characterization
Analyze test and field data to identify trends, validate performance, and drive design improvements
Collaborate cross-functionally with process, electrical, controls, manufacturing, and suppliers to deliver integrated solutions
Troubleshoot complex system issues using root cause methods and data-driven approaches
Ensure designs meet performance, reliability, manufacturability, and SEMI/safety requirements
Communicate design decisions, technical risks, and progress to stakeholders with clarity and ownership
