CAREERS / JOIN THE LAB

Help a good product find the people who need it.

Trinity EduLab builds 1일 1실모, a mathematics app where high-school students solve one paper a day and train the questions they missed. This role introduces the app to students and parents and finds its first users through content and social channels.

04 / WHO YOU WORK WITH

SUNGMIN KIM / FOUNDER & EDUCATOR

Before applying, meet the person you would work with.

“I want to build systems that carry great teacher judgment further, not answers that replace teachers.”

Years of teaching mathematics showed me how one strong explanation or one well-built question can reshape a student's thinking. Trinity EduLab builds systems that extend educator judgment rather than replace it.
