Torsten holds a Diploma for Applied Laser Technologies from the University of Applied Sciences in Emden, Germany in 1998. During further work at the Institute of Laser Technology in Emden and University of Loughborough, UK, he built a fully automatic laser lithography system for rapid generation of microstructures in submicron dimensions. He also developed a process to generate the world’s first in-glass diffractive optics using ion exchange processes in gradient refractive index glass, and which is still used today for the generation of waveguides in glass.

Torsten is Chief Executive Officer of ficonTEC Service and one of the co-founders of the company. When founding the company in 2001, the goal was to provide automatic and semi-automatic assembly and test solutions for the photonics industry.

Elfriede Schug, CCO

ficonTEC Service GmbH, Achim, Germany

Elfriede’s working career began in 1981 with the completion of the qualification as a Chef, this in parallel with her responsibilities as a single mother to her 4-year old daughter. After several years of successful employment, she then pursued and gained a second qualification (Bachelor, with distinction) in Business Economics with a Major in Controlling at the HWP Hamburg. In 1994 Elfriede assumed her first commercial, financial responsibilities for a food wholesaler, for which she also established Controlling.

Following the birth of her third daughter in 1999, and with a view to the inter-compatibility of both career and family commitments, Elfriede founded her own company with the goal of providing financial support services to start-ups. Towards the end of 2013 she took on an accounting role within ficonTEC’s financial accounting department. Elfriede’s responsibilities grew accordingly with the rapid growth of the company, and at the end of 2014 she became Head of Finance | Controlling.

One of the particular challenges of the rapidly growing organization at that point encompassed the implementation of an ERP system, which Elfriede has accompanied from the start. Since 2017 Elfriede is on the Board as CCO and is an authorized signatory for ficonTEC. Today, her focus lies with the on-going development of Controlling.
