The FTSEurofirst 300 index of top European shares was up 0.27 percent at 1,016.04 points.
Non-farm payrolls are expected have risen by 150,000 in December but hopes for an even stronger number were driven by a Thursday's survey showing private sector hiring surged last month. Initial jobless claims meanwhile dropped 15,000 in the latest week.
Bank shares gave up their small early gains, with the STOXX Europe 600 Banking Index 0.06 percent lower following big losses in the previous two sessions and UniCredit again lower.
Fears over the outlook for euro zone banks have grown since the Italian lender was forced to offer new shares at a deeply discounted price to shore up its crisis-ravaged balance sheet. UniCredit stock has fallen around 30 percent in the last two sessions and was down over 8 percent on Friday.
Commercial banks parked a new record 455 billion euros ($582 billion) overnight at the European Central Bank on Thursday, indicating they still prefer security with low interest rates to lending at higher rates to each other.

Yields on Italian and Spanish debt rose ahead of next week's bond auctions, seen as a test of whether weaker euro zone states will be able to refinance maturing debts. Italian 10-year paper was trading above the 7 percent level viewed as unsustainable for public finances.
Market players cashed in on German bonds before the U.S. jobs data, with the Bund future 18 ticks lower on the day at 138.61, after rallying 70 ticks in the previous session.
Renewed worries about Greece's ability to meet debt repayments, Spain's public finances and Austrian banks' exposure to struggling Hungary should limit any sell-off in safe-haven German debt, however.
"There are rising concerns in Europe about Greece, the budget deficit in Spain ... so clearly the environment remains favorable for a bid for safety, so the Bund will continue to outperform (and) spreads are still under widening pressure," said Patrick Jacq, rate strategist at BNP Paribas.
"I would say that whatever U.S. data (emerges) this afternoon, the risk will continue to be a key driving force."
As the vulnerable euro and European shares whetted appetite for safe-haven assets, gold was on course for its best week in a month at around $1,622 an ounce.
