Ask HN: How to Keep Improving as a Machine Learning Engineer

I am finishing my Masters in Computer Science in May, 2018. I am interested in becoming a Machine Learning engineer but currently I have got a job as a software engineer. I have a background in Machine Learning because of the courses I have taken at my university and following the Deep Learning Specialization in Coursera. However, I am not good enough to get a job as a Machine Learning Engineer now. I want to know how I can keep improving my skills and what should be my study plan?
