Technical Lead (Ruby/Java/Python, AI)

About Us In today’s world, where consumer tastes and preferences are diverse, marketing methods have become complex and varied, and the tendency is that only large companies and agencies with capital can reap the benefits of high-quality and effective marketing. Meanwhile, Japan’s working-age population continues to decline, and the cost and difficulty of retaining marketing talent in-house are increasing. Against this backdrop, the Novasel business was launched as a new business within the Raksul Group under the vision of “democratizing marketing.” Between 2014 and 2019, the Raksul Group invested more than 5 billion yen in TV commercials over five years and increased its sales twentyfold. Novasel has productized the marketing know-how gained in that process and has developed services such as “Novasel Analytics,” which instantly visualizes the advertising effectiveness of TV commercials; “Novasel Trend,” which allows you to view the TV commercial effects of approximately 5,000 brands for free; and “Novasel Professional,” in which professionals evaluate and improve marketing operations. Responsibilities In recent years Novasel has been focusing on developing solutions that utilize generative AI and machine learning. Meanwhile, the team is relatively young: members have high potential, but there is still room for organizational muscle to produce sufficient output continuously.
