I was PF; hand-flying.  On departure; we were cleared to 10;000 feet.  Northbound on the SID; climbing through approximately 7;500; I increased pitch to avoid a small build-up off the nose.  Climbing thru approximately 8;800 feet; I realized that I was going to have a difficult time leveling off by 10;000 feet.  I asked the CA to advise ATC of the potential altitude excursion and aggressively; but smoothly; reduced pitch to level off.  I exceeded our assigned altitude by 450 feet; and promptly descended back to 10;000 feet.  ATC did not seem concerned by our deviation and cleared us to 16;000 feet.This was one of my first sequences after a 6-month leave of absence.  The CA is new to the airplane and new to the seat.  These factors contributed to our poor altitude SA and slow cross-check.Our threat-forward briefing focused on our lack of recent flying.  We needed to be even more vigilant to trap decision and execution errors.
