Senior Mechanical Engineer

JOB DESCRIPTION

Senior Mechanical Engineer

Axcelis is seeking aSenior Mechanical Engineerto design and deliver critical hardware for next-generation semiconductor capital equipment. In this role, you willown subsystem designs and drive end-to-end engineering execution, developing solutions that directly impacttool performance, wafer-level outcomes, and customer productivity.

You will work on tightly integrated electromechanical systems wheremechanical design directly impacts system performance, throughput, and reliability, partnering with cross-functional teams to deliver differentiated technology to leading semiconductor manufacturers.

Role Focus and Impact

• Ownend-to-end design, development, and validation of mechanical subsystems
• Translate system and process requirements intorobust hardware solutions
• Directly influenceperformance, yield, and reliability at the system and customer level
• Operate as asystem thinker, connecting mechanical design decisions to overall tool behavior

Key Responsibilities

• Design and developmechanical subsystems and assemblies for advanced semiconductor equipment
• Own engineering execution fromconcept through validation and release, delivering complete solutions to technical challenges
• Translatesystem-level and process requirements into clear mechanical design requirements
• Performdesign tradeoffs and risk assessments, selecting optimal solutions based on performance, cost, and schedule
• Conductengineering analyses (tolerance, thermal, structural), validating designs through both simulation and first-principles calculations
• Plan and executestructured testing and validation, including prototype builds and experimental characterization
• Analyzetest and field data to identify trends, validate performance, and drive design improvements
• Collaborate cross-functionally withprocess, electrical, controls, manufacturing, and suppliers to deliver integrated solutions
• Troubleshoot complex system issues usingroot cause methods and data-driven approaches
• Ensure designs meetperformance, reliability, manufacturability, and SEMI/safety requirements
• Communicate design decisions, technical risks, and progress to stakeholders with clarity and ownership

Required Qualifications

• BS in Mechanical Engineering required (MS preferred)
• 8–12+ years of experience designing complex electromechanical systems
• Demonstrated ownership ofsubsystems or major components in a product development environment
• Strong proficiency in3D CAD and PLM tools (Creo/Windchill or equivalent)
• Solid experience withmechanism design, tolerance analysis, and engineering fundamentals
• Working knowledge ofFEA and analytical methods for design validation (Ansys preferred)
• Ability to independently drive design work while collaborating across teams
• Strong communication and problem-solving skills

Preferred Experience

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

Why Join Axcelis

• Own meaningful portions of a complex system—not just individual parts
• Work onhigh-value, differentiated technology used by leading chip manufacturers
• Gain experience in bothdetailed mechanical design and system-level integration
• Collaborate in ahighly technical, execution-focused engineering culture
• Clear path to advancement into Principal and Staff engineering roles

What We Are Looking For

• Ahigh-performing individual contributor who takes pride in delivering robust designs
• An engineer who understands howdetail-level decisions impact system-level performance
• Someone who thrives intechnically challenging, fast-paced development environments
• A collaborator who raises the bar throughstrong engineering discipline and design reviews
