I am 50+ year old, started my career as programmer in 1994, and progressed from there to software engg., sr. software engineer, project manager and now along with this doing practicing in data science and machine learning. and now looking for change to data science field in mnc company or abroad job etc. please suggest the right way to achieve such.

Ans: You can do that by doing some specific courses in data science. It will be challenging as you will compete with fresh graduates who will be highly skilled

Ans: Switching your career to Data Science/AI/ML can be a rewarding decision, given the increasing demand for professionals with expertise in these fields. With your previous experience in dealing with data for reliability analysis, you already possess a foundation that can be advantageous in transitioning to a career in data-driven roles.

Ans: Even though a career switch from a Doctorate in Mechanical Engineering to Data Science represents a transition that aligns with the growing interdisciplinary nature of modern research and industry I am of the view that you need to build on your years of academic experience in Mechanical Engineering by leveraging your doctorate in Data Science to further your career as a researcher professor in academia by contributing to cutting-edge research, guiding students, and shaping the field through your expertise.
Also explore consulting assignments in companies, especially in engineering and manufacturing, to help them use data science for optimization, predictive maintenance, and process improvement.
By wearing a Data Scientist in Engineering or Manufacturing hat marry your mechanical engineering background with data science skills look for roles that involve analyzing and optimizing engineering processes, designing experiments, and leveraging data for product development.
These are just two out of a host of options that you could explore by helping your university to build strong consulting practice and let your client see value and pay the top dollar. When that happens, the University will find ways to compensate your fairly for your value add.
