Is Management Engineering under the STEM strand in the US? 

In the US, "Management Engineering" is not a standardised or recognised academic program or degree. However, many universities offer degrees in "Industrial Engineering" or "Engineering Management" which are both considered STEM (Science, Technology, Engineering, and Mathematics) programs.

Industrial Engineering is focused on optimising complex systems, processes, and organisations to increase efficiency and productivity, while Engineering Management combines engineering principles with business management concepts to prepare students for leadership positions in technical industries. Both of these programs are considered STEM disciplines and typically require a strong foundation in math, science, and engineering coursework.

It's worth noting that STEM designation can vary by institution, and ultimately it is up to the individual universities to determine whether a particular program or degree falls under the STEM umbrella. However, in general, Industrial Engineering and Engineering Management are considered STEM disciplines in the US.
