Analytical Technician - CDI

Who Are We? Syntetica is decarbonising the textile industry through green chemistry recycling — starting with nylon. Today, most synthetic textiles are made from crude oil, and less than 1% are recycled back into new fibers. We're here to change that. At Syntetica, we’ve developed a patented depolymerization process that breaks down nylon-rich textile waste into virgin-equivalent nylon monomers — while separating materials like elastane, polyester, and cotton for further recycling. To date, we’ve raised >$35M from leading investors including EQT Ventures, Lululemon and MAS Holdings alongside the family offices of Peugeot, Etam and Indorama Ventures. We’ve already forged key partnerships with major textile players like Victoria’s Secret, Etam Group and Lululemon and have assembled a core team of 25 experts. We're now scaling industrially with a first demo facility built in partnership with Michelin. If you want to help bring truly circular materials to global scale, and solve one of the textile industry’s biggest sustainability challenges, come build with us!
