Be part of shaping next-generation optical technologies

Join NILT as a Production and Development Engineer, where you will work hands‑on in a world‑class cleanroom environment and play a central role in developing and fabricating high‑precision AR masters for customers around the globe. In this position, you will have excellent opportunities to grow your technical capabilities within nanofabrication, process optimization, and advanced metrology—while contributing to a rapidly expanding, international high‑tech company.

You will be based at our state-of-the-art clean room site in Vantaa, just few kilometers north of Helsinki Finland. As part of the Mastering team, you will collaborate closely with colleagues across Finland, Denmark, Sweden, and Switzerland. Our culture is collaborative, innovative, and quality‑driven, with a strong focus on precision, knowledge sharing, and continuous learning.

You will be part of an ambitious company where we win together. Team spirit and mutual success are key components in our everyday work culture.

Tasks and responsibilities

Manage Plasma processes in end‑to‑end fabrication workflows for AR masters

You will run and coordinate the plasma process flows for AR master fabrication, ensuring alignment with production plans, yield targets, and quality requirements.

Develop and optimize nanofabrication processes

You refine and innovate dry etch (RIE, ICP, IBE), and thin‑film deposition (PECVD) plasma processes to enhance performance, stability, and throughput.

Execute and document metrology for process verification

You perform SEM, AFM, ellipsometry, and optical inspections, generating complete and traceable documentation for internal use and for customer projects.

Define process windows and product specifications

You translate experimental data and capability studies into clear process capabilities and product specifications

.

Coordinate cleanroom activities across tool groups

You collaborate across lithography, etch, and deposition areas to maintain efficient flow and minimize bottlenecks.

Drive corrective and preventive actions

You investigate deviations, identify root causes, and implement improvements to strengthen process robustness.

Skills, experiences and qualifications we are looking for

• MSc (minimum) in nanotechnology, physics, materials science, electrical engineering, or similar
• Several years of hands‑on cleanroom experience with plasma etch and deposition tools in an industrial manufacturing environment
• Strong understanding of nanofabrication principles and their impact on process outcomes
• Experience with SEM, AFM, ellipsometry, and optical inspection
• Ability to document processes clearly and maintain complete, compliant records
• Proficiency in Python for analysis, data processing, and automation
• Ability to navigate complex multistep process flows under time‑sensitive cleanroom schedules
• Strong communication and collaboration skills across multiple locations
• Experience optimizing process windows or developing new process capabilities
• Experience designing DOEs and performing process capability studies is considered an advantage.
• Familiarity with quality systems, documentation practices, and deviation handling is considered an advantage.
• Fluent in English

Salary

The salary range for this position is EUR 5,400 – 6,200 per month, depending on experience, seniority and qualifications.
