Senior Research Engineer - ML & 3D Reconstruction

The i2CAT Foundation (Barcelona) is opening a position to advance in the research and innovation field of high quality 3D reconstruction, both offline and in real-time.

The candidate will join i2CAT’s Media Tech group, which is composed of over 20 experienced researchers and engineers in the fields of distributed and interactive multimedia systems and media processing, and is involved in relevant R&I projects with the European and national ecosystems, in close collaboration with key players from academia and industry.

This area is seeking a Senior Research Engineer with experience in the application of Machine Learning techniques applied to 3D/Volumetric reconstruction. The ideal candidate should have experience with different ML architectures and frameworks used in the field of Computer Vision and 3D reconstruction. The candidate should also be highly knowledgeable in pinhole camera modeling and parameterization. . Additionally, having experience in GPU programming is a plus (e.g.: CUDA/OpenCL). The candidate will be involved in cutting-edge research, innovation and development tasks. In particular, the candidate in charge of building custom datasets, designing and testing new algorithms and solutions in the field of 3D reconstruction and integrating the developed solutions into our platform.

The candidate should be highly self-driven while also capable of seamlessly collaborating hand-in-hand with different experts within i2CAT and highly relevant international partners from academia and industry under the umbrella of competitive national and international projects (Horizon Europe, European Smart Networks and Services Joint Undertaking, SNS JU).

The results from the planned research and development activities are expected to lead to high-impact scientific publications, technology/knowledge transfer (e.g., open-source software, patents, contributions to standards), resulting cutting-edge software and services, and career development opportunities.

The candidate, along with the 3D reconstruction team within Media Tech, will be involved in the development of novel methods to enhance the quality of our 3D holoportation system using advanced computer vision approaches. The candidate will also be in charge of exploring other 3D reconstruction solutions for tasks such as 3D reconstruction of large scenarios (e.g.: a city monument and surroundings) and offline high definition and high fidelity human reconstruction. Besides, the candidate will be actively involved in the development of Media Tech’s active National/European projects (Such as Didymos,XRECO and PRESENCE)

In particular, the candidate duties can be summarized as:

• Design and test new models to enhance the quality of our current real-time holoportation system.


• Integration of novel solutions in the current system.


• Explore and design novel 3D reconstruction methods for other relevant use cases such as large scenarios 3D reconstruction or high definition avatars.


• Third party technologies integration and innovation.
