Are you motivated by cutting‑edge nanofabrication and excited about pushing the limits of what optical components can do?

As a Nanooptics Prototyping Engineer, you’ll play a key role in developing world‑class masters and prototypes used in advanced optical applications across the globe. You will join a highly skilled team working in the DTU Nanolab national cleanroom, where you will help drive innovation, optimize fabrication processes, and ensure exceptional product quality. This position focuses on prototyping nanooptics for the visible spectrum and will focus on the fabrication and optimization of various oxide-based nanostructures.

At NILT, you will join a collaborative and international environment with close ties across our teams in Denmark and Switzerland. Our team is shaped by curiosity, precision, teamwork, and a strong commitment to continuous improvement. We are an ambitious organization where we win together, and team spirit and shared success are central to how we work every day.

Tasks and responsibilities

End‑to‑end fabrication of prototypes

Manage the full cleanroom workflow—from lithography to etch and deposition—ensuring timely delivery, high yield, and world‑class quality.

Process development and optimization

Design and run experiments (DOEs), refine process windows, and introduce improvements that enhance stability, throughput, and performance.

Metrology, inspection, and data documentation

Perform SEM, AFM, ellipsometry, and optical inspections and deliver complete, traceable data packages that meet our internal quality standards.

Specification and capability definition

Use experimental insights to define process capabilities, establish specifications, and secure robust, repeatable production flows.

Cross‑cleanroom coordination and troubleshooting

Coordinate own activities across lithography, etch, and deposition areas to reduce bottlenecks; review deviations and implement corrective/preventive actions.

Collaboration across Denmark and Switzerland

Work closely with colleagues across sites to synchronize process development efforts and support customer‑facing project requirements.

Skills, experiences and qualifications we are looking for

Required competences

• MSc in engineering or applied sciences (e.g., nanotechnology, physics, materials science, electrical engineering)
• Hands-on cleanroom experience and experience with one of the following key technologies you will be working with: E-beam lithography, dry etching, and thin-film deposition systems
• Experience with programming for data processing or automation
• Proficiency in nanofabrication principles and the ability to navigate complex, multistep cleanroom flows

Valued competences

• Experience working with and developing recipes for dry etching of oxides
• A relevant PhD in the field is considered an advantage
• Several years of hands‑on cleanroom experience operating e-beam, dry etching, and thin‑film deposition systems
• Experience with SEM, AFM, ellipsometry, and optical inspection
• Proficiency in Python for data processing, automation, and visualization
