Let's look at this a little differently. Find a non profit that you are interested in-- it could be the foodbank, Head Start, Boys and Girls club-- something that you are interested in. Go there and volunteer. You will find that your engineering skills will be used-- Oh, you may not design the next power plant or boiler room, however, in Head Start's case, you may help with a playground, a garden, a fencing project. Maybe look at some facility challenge and provide some engineering insight-- no, you would probably not get the hammer and nails and do the actual work, but you may provide some insight and ideas on what could be done.
If you were to redesign the playground, you may use your engineering skills in equipment placement, aid in a drainage issue, etc. If you go to the food bank, you may use your engineering skills in design of the lines that give out the food, stocking the boxes for the clients, etc.
There are lots of opportunities to use your engineering skills--and the non profits will be happy to have you. Yes, I have done all of this-- actually, ended serving on a Head Start board for 7 years and became the Chair of the Board-- not my plan, but how it worked out. You will use your engineering skills in ways that you never thought about before. Have fun! I do!
