Jeremy Witzens is a professional in their field. They is proficient in German, English and French. Colleagues describe them as "Jeremy worked on projects under my management (he was not a direct report to me) on all kinds of different tasks. These tasks included IC and PCB level circuit design, verification and testing, control system design, verification and testing, debug of extremely complicated phenomenon in our products, to name a few. Without exception and in all tasks he performed, his attention to detail, thoroughness in covering all design and verification space and his innovation were at the highest levels in the company and highest levels I've seen in my career. His approach to any design or problem entailed deep understanding of the underlying physics, properly modeling them and optimizing/debugging the design/problem in a structured and efficient manner. In addition to parametric and functional first silicon success for all circuits and systems he designed, he managed to isolate, root cause and propose solutions for at least 3 very difficult problems in the product that actually puzzled others for quite some time. Jeremy made lot of friends in the company and it was always a pleasure to work with him. I would definitely recommend Jeremy to any organization that embraces innovation, creativity and technological lead in their field." and "Jeremy is basically a scientist with strong opto-electronics, high speed digital (RF) and mix signal background, coupled with sound people skills and an effective team player. He and his team was the architect and implementor of all the solid state machines, feed back and control circuits and conrol loops that implemented the QSFP standards and more to the Luxtera active cable. As a Test Engineer I frequently needed to interface with him to get information and at times a more detailed implementation not only of his blocks but everything else because he has indepth knowlege of all the blocks from the revolutionary Luxtera nano-photonics semiconductor (MZI, Laser), its interface, feedback and controls all the way to the uController and High speed electrical interface. What's unique about working with Jeremy is that he is the mentor type and does not hold back sharing his knowledge. He also encourages you to think, feel comfortable to approach him and develop solutions as a team. As a result I have deeper understanding of our product, and enables me to develop test solutions with more coverage, smarter implementation and shorter test times. He is patient and open to ideas other than his own, tolerant to inquiries but with sound judgement to direct when decisions are needed to be made. Jermy's exemplary technical and interpersonal abilites would be beneficial to any organization, an empowering, team playing colleague and a mentor."
