Valkendorff is mentioned in 1553 as the king's secretary and was rewarded with the 1554 Fief of Bergenfor life. In 1556 he was also granted the fief of Vardøhus. He warned the government of Copenhagen about the threat against Danish economic interests that resulted from the British opening of a trade route north of Norway to Russia, avoiding the payment of Sound Dues at Helsingør. He was also successful in opposing the last remains of Hanseatic influence, which earned him the benevolence of King Frederick II. He also worked as a squire and local official. He confiscated illegally collected taxes and made the German clergy respect the ordinance and Bergen's superintendent. Mogens Gyldenstierne supported his initiatives. The Hanseatic League complained to the new king, Frederick II, about Valkendorff. The need for support from Lübeck in an awakening conflict with Sweden made the king appoint a new fier of Bergen, called Valkendorff home to Copenhagen and open an investigation of his governance. Valkendorff was outraged and a further conflict with the king over land interests on Funen sent him off to Saxony in exile.

Service in Copenhagen
Valkendorff's years as a journeyman ended when he was appointed to treasurer in 1564. He handled the office with great efficiency and managed to reduce national debts. He was also appointed to stadtholder of Copenhagen. When Peder Oxe, the king initially failed to appoint a new Steward of the Realm but Valkendorff was put in charge of Bremerholm and the Nacy. In 1576, a reluctant Frederick II appointed him to Councillor of the Realm. After the death of Frederick II in 1588, Valkendorff assumed control of the guardianship of Christian IV. As "rent master" he delivered the dowry of 75,000 Danish dalers to James VI of Scotland, who had married Anne of Denmark in 1589. Valkendorff argued with Peder Munk about defects in the fleet that had prevented Anne of Denmark sailing to Scotland in September 1589. In the summer of 1590 the problems were blamed on witchcraft. Several women, including Anna Koldings, were accused and executed. His powerful position led to his downfall. In 1590 he had to vacate all his offices after accusations of abuse of power and the judicial murder of Magnus Heinason. Though not quite unjustified these accusations were probably mostly politically motivated. For some years Valkendorff kept in the background but gradually he regained his influence and at the accession to power of the young Christian IV in 1596 he was at last appointed Steward of the Realm, a post he kept until his death. During these last years of power he still showed himself energetic but somewhat more cautious.
