Description: The role involves supporting cleanliness qualification and optics lifetime initiatives for semiconductor capital equipment. The individual will independently operate gas chromatography-mass spectrometry systems to identify and quantify molecular contamination. Responsibilities include designing test protocols, executing experiments on materials and subsystems, and interpreting complex spectral data. The position requires driving root-cause investigations and collaborating with cross-functional engineering teams to address contamination issues. Additionally, the role entails managing lab inventory, maintaining instrumentation, and ensuring compliance with internal and industry standards. Required Qualifications and SkillsCandidates must hold a Bachelor’s degree with at least 3 years of experience, a Master’s degree with at least 1 year of experience, or a PhD in Chemistry, Material Sciences, Chemical Engineering, or a related technical field. A minimum of 3 to 7 years of hands-on experience with GC-MS is required, specifically including dynamic headspace thermal desorption. Applicants must demonstrate the ability to design material cleanliness test protocols and work independently on instrument troubleshooting and data analysis. Proficiency with GC-MS data software and library searching is necessary.

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.
