Well, that depends what you mean, if you're asking 'did they ever share a front line', then the answer, to the best of my knowledge, is no. The theatres that the Soviets were involved in (Eastern Front and Manchura) were not in any form directly connected until April 25, 1945 just around two weeks before fighting in Europe concluded.

However, there was a Free-French fighter squadron that fought with the Soviets on the eastern front the Normandy-Niemen Squadron.

So not in the sense that there were boots on the ground fighting along-side one another. But in the skies, yes, French Pilots mostly in Soviet aircraft did indeed fight alongside the Soviets.
