Einstein did not seem to expend a lot of thought on philosophical musings. His greatest successes were achieved by considering what was physically observable. Einstein made statements that could be seen as mild supportive of intelligent design. Einstein never strayed far from what he knew best.
BTW, while not a religious Jew, he was a Zionist, before the Nazis came to power. He never visited the Soviet Union despite numerous invitations. He stated that he did not wish to appear to lend legitimacy the regime. He also only left the United States once after coming here in 1933. On that he occasion he and his wife took a cruise to Berumda, where they spent one day applying for an immigration visa and reentered on an immigration visa so they could become eligible for citizenship. He could have all the waivers and favors he wanted, but he wanted go through the process.(He originally entered on tourist visa, but on the advice of friends in Germany did not return to Germany.)
He also publicly and openly opposed a nuclear freeze in the 1950's, arguing that leaving the field open to the Soviets would result in certain disaster. He was nowhere near as naive as some of his would-be acolytes.
