Amateur career
Cijntje was born in the Netherlands and grew up primarily in Willemstad, Curaçao. He switch pitched and played shortstop for Willemstad in the 2016 Little League World Series. Cijntje played second base and batted second for the Netherlands under-15 team at the 2018 U-15 Baseball World Cup in Panama. He had a 1.076 on-base plus slugging and 6 RBI while committing two errors in eight games at the tournament. He also participated in the Reviving Baseball in Inner Cities (RBI) program in Curaçao.Cijntje moved to Miami when he was 16 years old, where he lived with three older cousins who had played college baseball at Florida National University. He attended Champagnat Catholic School in Hialeah, Florida, where he played baseball as both a switch pitcher and switch hitter. His high school [Win–loss Win–loss record (pitching)|record (pitching)|record] was 7–6 with a 2.32 earned run average (ERA), striking out 166 batters in 81 innings. He committed to play for Mississippi State University before his senior season. He enrolled there after not signing with the Milwaukee Brewers, who selected him in the 18th round of the 2022 MLB draft as a shortstop. Because he threw right handed as an infielder, his right throwing arm became stronger than his left.
Mississippi State
Cijntje began his freshman season with the Bulldogs as a mid-week starting pitcher. In his first collegiate start, he struck out seven Louisiana–Monroe batters, six while pitching right-handed and one as a lefty, while allowing one hit and one walk over four innings. He finished the season with a 3–5 record and 8.10 ERA in 14 games, 13 of the starts. He had 63 strikeouts in 50 innings pitched.
As a sophomore in 2024, Cijntje was named a second-team All American by the National Collegiate Baseball Writers Association and Perfect Game and was named to the South All-Region first team by the American Baseball Coaches Association. He finished the season with an 8–2 record and 3.67 ERA over 16 starts. He had 113 strikeouts in innings pitched. Cijntje pitched primarily as a righty in 2024, not throwing a pitch left-handed for the final month of the season. Mississippi State pitching coach Justin Parker said Cijntje would often forego the platoon advantage and pitch with his right arm to left-handed batters to improve his consistency. Parker said Cijntje had higher velocity and better command with his right arm but induced more groundballs as a lefty.

The Seattle Mariners drafted Cijntje with the 15th overall pick in the 2024 Major League Baseball draft on July 14, 2024. He signed a $4.88 million contract with the Mariners on July 16.

He began the season with the High-A Everett AquaSox. On May 18, he took a no-hitter into the sixth inning in a win over the Vancouver Canadians, pitching left handed to only three batters. He won the Northwest League's Pitcher of the Week award for that performance. Early in the season, he threw three left-handed relief appearances, allowing 9 runs in 3 innings. Cijntje pitched a scoreless inning in the 2025 All-Star Futures Game, throwing left handed to one batter. On August 3, Cijntje was promoted to the Double-A Arkansas Travelers.
