You need a large moon to skim atmosphere and slow rotation, you need a magnetosphere which means a spinning core. You also need active plate tectonics. And that is just for simple life too evolve.
As said earlier, there are certainly extremophiles who thrive in environments that are inhospitable. Heck, we know there's a giant ocean underneath the ice of Europa, which gets warmed and melts every so often to keep the ocean from freezing over due to the gravitation pull of Jupiter that literally warps the surface. If I had to guess, then perhaps tube worms of the type found on the Earth's ocean floor could be there.
My point was in regards to complex life. let me ask is there plate tectonics on europa? If there isnt whatever life was there is probably dead now.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
