Amateur In his youth, Jandric typically played as a forward, like his brother Steven. Around the age of 10, he changed position to a defenseman, reasoning that his skating skills were sufficient and it would be easier to make rosters that way. Jandric played
minor hockey for the Cariboo Cougars of the
BC Hockey Major Midget League (BCMML) from 2014 to 2016, where he was briefly the teammate of future
NHL forward
Dylan Cozens.
Collegiate Following time in minor hockey, Jandric spent time with the
Vernon Vipers of the
British Columbia Hockey League (BCHL) before committing, along with his brother, to the
University of Alaska Fairbanks (UAF) of the
National Collegiate Athletic Association (NCAA). He regularly worked out at a
CrossFit gym in
Prince George, British Columbia during the offseason, in order to physically keep up with the rigors of
college hockey, and with an eye on constant improvement. In
2019, Jandric made the
WCHA All-Rookie Team and, in total, appeared in 63 games for the school. After UAF opted out of the
2020–21 season due to concerns surrounding the
COVID-19 pandemic, he would take the year off in order to strengthen his body before transferring to the
University of North Dakota (UND). Jandric described the opportunity as "once-in-a lifetime", and stated his goal was to win the
NCAA ice hockey championship. His coach,
Brad Berry, described Jandric's speed/agility as both "high end" and "elite". as well as the Academic All-NCHC Team.
Professional On March 27, 2023, Jandric was signed to a two-year contract by the
Rochester Americans of the
American Hockey League (AHL), with a
professional tryout (PTO) for the remainder of the
2022-23 season. In his AHL debut versus the
Utica Comets, he recorded an assist. Jandric was one of 35 players invited to the 2023
Buffalo Sabres Development Camp, along with former teammate Matteo Costantini, who was selected by the Sabres in the fifth round of the
2020 NHL entry draft. He was also part of the roster for the team's annual Prospect Challenge Tournament. Following signature to a PTO, he was invited to Buffalo for the initial portion of NHL training camp, but was released nine days later so he could take part in the respective training camp for Rochester. On October 9, it was announced that Jandric had been assigned to the
Jacksonville Icemen, the
ECHL affiliate for both the Sabres as well as the Americans. He recorded his inaugural ECHL point on the Icemen's first goal of the season, with an assist. After collecting a total of two assists in six games with the Icemen, Jandric was recalled to the Americans on November 6, 2023. He would play in seven games for Rochester, recording no points, before being reassigned to Jacksonville on December 29. Thereafter, Jandric scored his first professional goal on January 3, 2024, and followed that up with a game-winning
overtime goal on January 6. On January 11, Jandric was traded to the
Laval Rocket in exchange for defenseman Noah Laaouan, and subsequently assigned to the
Trois-Rivières Lions of the ECHL. He would notch three assists in six games with the Lions before being recalled to the Rocket on February 1, but was reassigned on February 3 without playing a game. Jandric was recalled yet again by the Rocket on February 7, and made his franchise debut against the
Wilkes-Barre/Scranton Penguins on February 17 after an injury to
Mattias Norlinder. He then returned to the Lions on March 18. His final movement between teams for the season came on April 8 and April 16 respectively. Spending the majority of the
2024–25 season with Trois-Rivières, Jandric was assessed a one-game suspension following an incident on January 18, 2025 against the
Norfolk Admirals in which he received a
match penalty for
cross-checking. Just days later, he was named as part of the league's Midseason All-Star Team. After finishing the ECHL season at a nearly point-per-game pace, Jandric was an instrumental part of the Lions' first
Kelly Cup win, scoring the championship clinching goal in a 4–1 victory in game 5. In July 2025, Jandric signed his first contract overseas, agreeing to a one-year contract with
ERC Ingolstadt of the
German-based
Deutsche Eishockey Liga (DEL). ==Personal life==
