Engel, nicknamed "Jurek", began playing in midfield or attack before, at the age of 22, being cruelly forced to cut his career short because of injury. With spirits dampened only slightly, he immediately turned to coaching and took over at Polonia Warsaw in the 1976/1977 season.
In 1985 Jurek took over at Legia Warsaw, leading them to two second place finishes in the Polish Championship in three seasons. Just as he was becoming well known he made the strange decision to move to Apollon Limassol, in Cyprus, an island he stayed on for seven years.
He later returned to Legia before taking Polonia Warsaw to runners-up spot in 1998–99.
With the side lacking firepower when he took charge, Engel saw the qualities in Nigerian-born Olisadebe who was already playing his league football in Poland. He asked the president to speed Olisadebe's papers through and as a result, had a talented forward available for World Cup qualifying. Olisadebe rewarded his coach with eight goals in ten qualifying matches.
The World Cup did not go well and Poland were eliminated in the first round. The opening two games provided two resounding defeats losing to South Korea and Portugal. After being knocked out of the tournament and now without any pressure to perform, Poland beat the United States in their final group game for a famous victory.
His most recent vocation was at Wisła Kraków where he was trainer until late-October 2005 and he has also been sports director of Legia Warsaw. In December 2005, he moved back in Cyprus and headed the coaching team of APOEL. He led the team into the third place of the Cypriot Championship, just two points from the top, and won the Cypriot Cup as well.
