Under the mission of “realizing a society where people can live out their natural lifespan,” the company aims to create a future where lives are no longer cut short by diseases like cancer. In Japan, it’s said that 1 in 2 people will develop cancer - a challenge humanity has been unable to overcome for over 4,000 years. Meanwhile, cancer screening rates remain around 40%, meaning many people miss the chance for early detection.\nCraif is using technology to overcome these psychological and social barriers, tackling the fundamental challenge of creating a society where everyone can naturally take steps toward prevention and early detection.\nRecruitment Background & Career Path\nAdvanced data science expertise spanning both machine learning and biology is essential for improving the accuracy of testing systems like miSignal and developing new methods.
