PT Ketrosden Triasmitra, Tbk (Triasmitra Group) is a leading telecommunication infrastructure company in Indonesia, specializing in submarine and inland fiber-optic backbone networks. We design, build, own, and maintain fiber-optic cable systems, supported by 24/7 managed services to ensure reliable and sustainable connectivity.
Founded in 1994, Triasmitra has grown from a contractor and trading company into a trusted EPC provider (Engineering, Procurement, and Construction) with strong expertise in fiber-optic deployment. Since 2007, we have also expanded into marine-based projects for telecommunications, mining, and oil & gas industries, covering survey, engineering, permitting, project management, procurement, and construction.
As the first Indonesian company to deploy submarine fiber-optic cables, Triasmitra has successfully developed and managed over 10,000 km of networks across Indonesia and beyond. Headquartered in Jakarta, we operate site offices in Batam, Bintan, Bangka, Surabaya, and Singapore.
Pros: They do offer hybrid work for some roles, which is a big plus. As a Project Coordinator, I could work from home a couple of days a week. That flexibility is good for personal appointments.
Cons: Honestly, the 'flexibility' can be pretty limited, especially when projects are tight. You're expected in the office for most meetings, even for hybrid staff. It's not truly remote-first; it feels more like a corporate environment forcing onsite presence.
Advice to Management: Seriously consider more true remote options. Trust your employees more with how they manage their time, not just their location.
