Junior UI/UX Designer
Full-time
In-person

At Interstellar Lab, our mission is to build a future full of life, on Earth and beyond.
We believe in a world where technology enables humans to live in harmony with nature, where biodiversity thrives and expands, and where terrestrial life becomes multi-planetary.

To build this future, we design autonomous biospheric systems to grow plants with precision, on Earth and in Space. Our AI-powered BioPods and BioCapsules leverage biosciences to reproduce and optimize growth conditions for a wide variety of high-value plants.

On Earth, we pioneer molecular and biofarming, boosting the production of metabolites and bioactive compounds while offering sustainable, traceable, and high-quality natural ingredients to the beauty, fragrance, pharmaceutical, and nutraceutical industries.

In space, we collaborate with agencies and private companies to develop biofarming units that advance life science research in microgravity and lay the foundation for future biofactories in space, enabling innovative terrestrial applications and long-duration space missions.
