About the project
The Tarranix Project is developing a three-dimensional photonic chip based on optical transistors capable of processing up to six logical states through light polarization, overcoming the limitations of current binary electronic and quantum systems.
Through the controlled manipulation of polarization and the integration of multilevel logic gates, a new era of ultrafast, energy-efficient, and scalable computing is emerging.
We are seeking a Nanofabrication Engineer with experience in micro/nanofabrication to lead the transformation of simulated designs into real photonic devices with sub-nanometric precision.
Purpose of the position
To design, fabricate, and validate
three-dimensional photonic prototypes
using advanced lithography and nanoprinting techniques.
The engineer will be responsible for turning simulated models into functional physical devices, ensuring
structural precision
,
optical efficiency
, and
manufacturing scalability
.
Key responsibilities
* Operate electron beam lithography equipment (Raith EBPG5150) and PECVD systems.
* Execute 3D nanoprinting processes.
* Integrate optical components such as waveguides, polarizing filters, and birefringent crystals.
* Perform structural validations using SEM microscopy and Raman spectroscopy.
* Document fabrication processes and establish
reproducibility protocols
.
* Collaborate with the
simulation and materials teams
to optimize production parameters.
Requirements
* Bachelor's or Master's degree in Materials Engineering, Nanotechnology, or Applied Physics/Chemistry.
* Minimum of 3 years of experience in micro/nanofabrication or advanced lithography.
* Knowledge of deposition, alignment, and structural validation processes.
* Ability to work in
cleanroom environments
, following strict safety procedures.
* Strong attention to precision, quality, and innovation.
Position details
* Annual gross salary: €25, monthly payments).
* Performance bonus: equivalent to 10% of the annual gross salary, linked to the final validation and technical success of the project.
* Location: Carrer d'Amadeu Torner, 33, 08902 L'Hospitalet de Llobregat (Barcelona).
* Access to state-of-the-art photonic equipment and collaboration with external laboratories and cleanrooms.
* Integration into an interdisciplinary team of physicists, engineers, and scientists in an applied innovation environment.
* Upon project completion, if the role remains necessary and performance evaluation is positive, there will be the possibility of renewal or conversion to a permanent position, depending on scientific needs and available funding.
