It depends. The public officials charged with (among other things) the final responsibility for legal and judicial matters were the Praetors, elected for a one-year period. They sometimes officiated as judges themselves - in cases 'worthy of their attention'- but in most cases they appointed others as judges. In civic disputes the Praetor rarely figured; there the parties together chose a judge they could agree on - a bit like in today's mediation.
Anyone could act as judge who was a free-born Roman citizen who had put his name on a list of people available and willing to do the job. No legal training was required. A judge could call on a outside lawyer for expert advice, but was not bound by his opinion. These judges could be appointed or chosen as long as they were willing and able, and on the list, so they had no fixed term of office.

The consuls serve as judges in the early period of the Roman Republic, from 509 B.C. (the year of the establishment of the republic) to 366 B.C., when the praetors were created to relieve the consuls of their judicial duties. The praetors were chief justices in charge of the implementation of the law in courts. They presided over some trials. For other trials they instructed judges (judeces). In addition they also had the power to command an army.
Samuel was the last of the Judges, and did not serve as king. He was active around 900 BCE for several decades.

During the period of the Roman Republic judges were not people with a professional career. The Praetor, the chief justice, chose the judges to preside over a trial from a list of wealthy men. Often he presided over trials himself. His term of office was one year. During the period of rule by emperors, the emperors often presided over trials. They often delegated this task to the praetors, who were now civil servants of the imperial government. They staid in office for as long as it pleased the emperor.
