Senior Mechanical Engineer – End-to-End SEMI Equipment Systems

Axcelis Technologies; Beverly (MA); On-site; USD 121,000 - 182,000; Full time

Job summary

Axcelis Technologies is seeking a Senior Mechanical Engineer to design and deliver critical hardware for next-generation semiconductor capital equipment. You will own subsystems and drive end-to-end engineering execution, directly impacting tool performance, wafer-level outcomes, and customer productivity.

You will work on tightly integrated electromechanical systems where mechanical design affects system performance, throughput, and reliability, collaborating with cross-functional teams to

Qualifications

• BS in Mechanical Engineering is required; MS preferred.
• 8–12+ years of experience designing complex electromechanical systems.
• 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.

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.
