Where to hide something massive in the galaxy?

This is somewhat vaguely related to a old question of mine involving a alien species who spend three thousand years developing a post singularity spaceship armada in the mantle of a lava planet (Industrious). I try being realistic.

So realistic that I figured that might somehow not work as planned. My logic at the time was so sound too! "Can't hide in space because of heat signature? Well, let's find some extremely hot place and hide in it where looking for heat signatures is impossible and no one will look anyways". Turns out trying to make a massive underground base in a lava planet has lots of problems. Problems that you can only throw so much technology at.

So I wonder.

Where in the galaxy is a safe place to hide from some genocidal spaceship entities who wanna kill everyone? And I mean anywhere in the galaxy. Empty space is not a option, too easy to be seen. Cold planets I presume would be useless because of the lack of heat. However, where in the Milky Way galaxy is a safe place to hide from swarms of genocidal aliens that kill anything they detect on sight while building a giant space fleet?

-Will a lava planets work? -What about a hot jupiter? -What about near the galactic center? -Are globular or open clusters good or do they come with problems like being too much of landmarks? -Do red dwarfs or brown dwarfs hide things well enough or are they too cold to hide heat signatures?

Technological limits are very few here, but hyper-spatial options aren't available. FTL speeds are around 10-20 Ly per day. Wormholes would require moving to other star systems if used.
