About the role

JOB DESCRIPTIONSenior Mechanical Engineer 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. Role Focus and ImpactOwn 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

Key Responsibilities:

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

Required Qualifications:

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
Preferred Experience
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

Why Join: Axcelis Own meaningful portions of a complex system—not just individual parts Work on high-value, differentiated technology used by leading chip manufacturers Gain experience in both detailed mechanical design and system-level integration Collaborate in a highly technical, execution-focused engineering culture Clear path to advancement into Principal and Staff engineering roles

What We Are Looking For:

A high-performing individual contributor who takes pride in delivering robust designs
An engineer who understands how detail-level decisions impact system-level performance
Someone who thrives in technically challenging, fast-paced development environments

A collaborator who raises the bar through strong engineering discipline and design reviewsEQUAL OPPORTUNITY STATEMENTIt is the policy of Axcelis to provide equal opportunity in all areas of employment for all persons free from discrimination based on race, sex, religion, age, color, national origin, disability status, medical condition (including pregnancy), veteran status, sexual orientation, marital status, or any other characteristic protected by federal, state or local law.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
