Yes, it's called easy templates.
Org mode supports insertion of empty structural elements (like
‘#+BEGIN_SRC’ and ‘#+END_SRC’ pairs) with just a few key strokes. This
is achieved through a native template expansion mechanism. Note that
Emacs has several other template mechanisms which could be used in a
similar way, for example ‘yasnippet’.
To insert a structural element, type a ‘<’, followed by a template
selector and ‘TAB’. Completion takes effect only when the above
keystrokes are typed on a line by itself.
For your precise question:
<s then TAB.
See others in the documentation.
Note it's not specific to spacemacs, since it's from native org-mode
