A Note for Future Colleagues
"You can experience everything a System Engineer does."
- I worked as a System Engineer in a mobile service company handling massive traffic before joining Toss Securities. In my previous role, I supported numerous platforms, but while working at Toss Securities, I realized that I had been operating without understanding the fundamental principles behind the infrastructure systems. At Toss Securities, we closely collaborate with various departments within the infrastructure. As a System Engineer, I have come to understand the overall architecture and learned various technologies that have illuminated the principles of infrastructure systems. I highly recommend Toss Securities to those System Engineers who want to avoid complacency, love their work, and wish to make a quantum leap in their careers within the best environment for engineers!
