I can only speak from my experience, but Lockheed Martin is incredibly supportive of STEM education and encourages employee volunteerism. They have a program to support time off from work for volunteer causes.

When deciding where to work, I would also consider finding a position that interests you, a place where the company/team culture suits you, etc. - but supporting volunteerism and STEM education is definitely a good thing to include in the list of considerations.
