I Like these parts of the three jobs discriptions.

"Design and develop advanced photonics packaging process technology, and renders major contribution in transforming DenseLight inhouse APT operations (Assembly, Packaging & Test Process) to a world-class Hybrid PIC (Photonics Integrated Circuit) manufacturing operation --- of high performance and low cost lasers and transceivers products for the global markets for data-centers interconnects, data-communications and photonics sensors"

"Reduce deviations the transfer of new production process to external outsource vendor as per supplier qualification flow"

There is much more to like and more if I could understand the technical terms.
