Even in the IT industry with no experience, you can advance your career with our unique support system. I learned about English in college, but I was interested in the IT industry.
While researching, I learned about the "CCIE 8-title & CCDE" of the CEO of Root Riff. I was inspired to work under someone with such high-level certifications worldwide and decided to join. What surprised me after joining was the comprehensive support system for certification.
There are "study leaves," virtualized Labs, and the company even covers the costs of equipment for home study. There's also an incentive when you obtain a certification, which is motivating. There are many seniors with certifications, and it's comforting to know that I can consult them anytime. Currently, I'm involved in verifying and inspecting large-scale carrier networks. It's a responsible job where mistakes are not allowed, but it's motivating when customers are pleased.
In the future, I aim to obtain certifications and also get involved in training new employees. I also want to utilize my English skills in business dealings with foreigners. For those with ambition and a desire to skill up, Root Riff is the ideal company.

I was appointed as a leader just one year after joining, and I can actively gain experience. I want to deepen my knowledge and be someone clients specifically request.
While researching "I want to change jobs and work in IT," I became interested in Root Riff, where many network experts gather. I applied, thinking it would be a place where I could challenge myself.
At first, I was nervous, thinking it might be hard to approach so many amazing people. However, that wasn't the case. After joining, when I was studying alone, a senior casually approached and taught me various things. There were also times when I was invited to observe work.
One of the best things about Root Riff is that you can actively gain experience. I was surprised to be appointed as a leader just one year after joining, but with the help of my team and by asking seniors and researching, I was able to accomplish the tasks. It's great that you can gain real-world experience and grow.
Currently, I'm involved in designing, constructing, and testing large-scale networks. It's rewarding and fun to solve problems using my knowledge and experience when issues arise. My future goal is to learn more and become someone clients specifically request.

Contribute to organizational expansion while leveraging my skills.
Aim for career advancement beyond the engineer frame!
The reason I joined was that I received a direct offer from the CEO, who was aiming for organizational expansion. I was also focusing on SNS operations besides being an engineer, so I thought I could gain valuable experience that I couldn't get in a regular company by utilizing my specialized skills.
What I find rewarding now is contributing to organizational creation and increasing sales. For organizational creation, I regularly hold online study sessions for external purposes, and I'm active in increasing the number of people interested in our company. For internal purposes, I support employees by preparing in-house facilities for solid learning and creating training materials.
Regarding sales, I find it rewarding to go out for sales with the sales team and increase the numbers. My future goal is to expand the company to a scale of 100 people. Personally, I want to be more deeply involved in recruitment, technical training, organizational creation, and project acquisition beyond the engineer frame.
Root Riff has many projects where you can improve your skills, and many people are passionate about their work. Both human and technical support systems are well-established, making it an ideal environment for those who genuinely want to grow.
