Move your a.bio in your HTML, because ~ is a sibling selector (however less strict than the +), and use position to stay as it was before moving the HTML:

Snippet

.executivo .pic::after {
  background-color: #00845b;
  content: "";
  height: 100%;
  left: 0;
  position: absolute;
  top: 0;
  width: 100%;
  opacity: 0;
  transition: .3s ease-in-out;
}
.executivo {
  position: relative;
}
.executivo a.bio {
  position: absolute;
  bottom: -20px
}
.executivo a.bio:hover ~ .pic img {
  opacity: 0.35;
}
.executivo .pic {
  margin-bottom: 45px;
  position: relative;
}
.executivo .pic img {
  display: block;
  max-width:100% /*demo*/
}
