Engineer, Field Process – Thermal ALD (Phoenix, AZ)

As a member of the Global Sales and Services business unit, our HVM (High Volume Manufacturing) Field Process Engineering team serves as the on-site technical bridge between our customers, ASM Field Service, account leadership, and global product teams.

In this role, you will support ASM Synergis and Pulsar thermal ALD deposition systems at our customer fab in North Phoenix. You will work closely with the customer and internal teams to support process performance, equipment qualification, tool-to-tool matching, troubleshooting, and continuous improvement in a high-volume semiconductor manufacturing environment.

This is an excellent opportunity for an early-career engineer who wants to build hands-on experience with thermal ALD, thin-film deposition, semiconductor processing, and advanced semiconductor equipment. New College Graduates are encouraged to apply.

What you'll be working on

• Support ASM Synergis and Pulsar thermal ALD systems through installation, start-up, qualification, HVM ramp, and production-support activities.
• Monitor process performance, tool-to-tool matching, process stability, and customer specifications through structured data review and follow-up.
• Support troubleshooting and resolution of process and equipment-related issues in partnership with Field Service Engineers, customer engineers, and global technical teams.
• Assist with experiments and data analysis for process qualification, troubleshooting, continuous improvement, and process-window optimization.
• Collect and analyze process, metrology, tool-state, and chamber-performance data to support technical decision-making.
• Apply structured problem-solving techniques, DOE, SPC, baseline comparisons, and statistical analysis to understand process behavior.
• Support analysis of thin-film characteristics including thickness, uniformity, particles/defects, composition, and other relevant process outputs.
• Clearly communicate technical findings, actions, risks, and next steps to customers and internal stakeholders.
• Document issue timelines, experimental results, troubleshooting activities, action plans, and lessons learned.
• Support critical customer needs and escalations while maintaining strong discipline around safety, controlled changes, confidentiality, and customer/ASM intellectual property.

What we are looking for

• Bachelor's or Master's degree in Chemical Engineering, Materials Science, Chemistry, Electrical Engineering, Mechanical Engineering, Physics, or a closely related technical discipline.
• 0–3 years of relevant experience. New College Graduates are welcome to apply.
• Academic, research, internship, or industry exposure to thermal ALD, thin-film deposition, semiconductor processing, surface chemistry, reaction kinetics, vacuum systems, gases/pressure/flow, or related technologies.
• Ability to analyze experimental and process data using tools such as JMP, Python, MATLAB, Excel, or similar analytical tools.
• Strong technical fundamentals and ability to learn complex semiconductor processes and equipment.
• Strong English communication skills and the ability to communicate effectively with customers and cross-functional teams.
• Ability to work on-site in a customer semiconductor fab and cleanroom environment in North Phoenix.
• Strong ownership, accountability, organization, and attention to detail.
• Ability to remain structured and communicate clearly while working through urgent or incomplete technical information.
• Flexibility to support extended hours or weekends when required for qualifications, escalations, or critical customer needs.
• Ability to travel as needed for training or technical support.

What sets you apart

• Hands-on academic, internship, research, or industry experience with thermal ALD or thin-film deposition.
• Familiarity with ALD fundamentals, including precursor chemistry, surface reactions, temperature effects, film growth, uniformity, and process optimization.
• Experience with semiconductor equipment manufacturers, OEM suppliers, or semiconductor manufacturing environments.
• Experience with DOE, SPC, statistical analysis, metrology, or characterization of thin films.
• Previous cleanroom, fab, laboratory, or semiconductor equipment experience.
• Strong customer-facing mindset and ability to collaborate effectively across technical teams and cultures.
• Mandarin proficiency is a plus, but not required. Strong English communication skills are required.

Key attributes for success

We are looking for someone who brings:

• Strong ownership and accountability.
• Curiosity and learning agility.
• A hands-on technical mindset.
• An interest in thermal ALD, thin films, and semiconductor equipment.
• Strong analytical and problem-solving skills.
• Clear, professional communication.
• Comfort working in a fast-paced customer fab environment.
• A collaborative approach when working with Field Service, customers, and global engineering teams.
