About us
At Renasens, we’re a small team building something ambitious: a textile recycling technology that will change the world.
We have developed a waterless process using minimal energy and chemicals with a neutral impact on fiber quality. This allows us to recycle the most challenging textile waste: blended post-consumer polycotton in any colour, with any additives, composition, or quality, utilizing what is currently the most common yet unwanted fraction of textile waste.
We are now building a first-of-its kind facility in Borås, Sweden and looking for brilliant people to join our journey.
Role overview
We are seeking a skilled Textile Engineer with strong expertise in mechanical processing, including experience with recycling and quality control processes. In this role, you will support day-to-day production, conduct tests, and work hands-on with our equipment and processes to ensure high-quality output.
Your insights will also help us identify improvements and drive continuous optimization across technology to scale from laboratory to pilot scale.
Responsibilities
Responsible for the physical separation part of our recycling process.
Perform detailed material characterization and analysis of recycled fibers and textiles to ensure quality and performance.
