【Why WITS Japan / Osaka?】
★Average Monthly Overtime: 11.6 Hours★
Some projects involve almost no overtime. Additionally, with an annual paid leave usage rate of 77%, it’s easy to balance work and private life.

★Low Attrition Rate: Just 0.8%★
Four out of five members in management and sales roles are former engineers, ensuring a deep understanding of engineers’ needs and a strong focus on creating an engineer-first work environment.

★Robust Reward Systems★
In addition to biannual bonuses, there is an interim reward system twice a year, with up to ¥600,000 provided.

★Unique Opportunities to Connect with Taiwan Headquarters★
Every January, a year-end party is held at the Taiwan headquarters. Exceptional employees from Osaka and Tokyo are invited to Taiwan for this event.

★Comprehensive Qualification and Reward Systems★
We offer qualification allowances for certifications such as IT Passport and Project Manager. Additionally, vendor exam success is rewarded with reimbursement of exam fees and an extra bonus. These systems are designed to encourage skill development. (Limited to company-specified qualifications)

“An Environment That Encourages Growth”
Recently, veteran employees have voluntarily held regular weekend workshops on programming and project management for younger team members. These workshops are well-attended, and employees actively work on improving their skills. It’s a great environment for those eager to grow, and I’ve found it very inspiring.
