Who We Are
The Manila Processing Center started way before 2014. With a few IT and Finance staff supporting the rollout of SMEC Group's ERP, EPICOR, the beginnings of what would eventually become Global Shared Services was formed. Throughout the first 3 years, GSS experienced substantial growth reaching 88 employees supporting what then grew to a wide array of services supporting the SMEC Group including IT, Finance, Human Resources and the introduction of the BMS team.With the acquisition of SMEC by the Surbana Jurong Group in 2017, a greater opportunity presented itself for GSS. It was then poised to grow and provide services to a larger group of companies and future potential acquisitions. As GSS services were introduced to more companies and locations, GSS saw its size double, from 88 to 200, unique and talented individuals by 2019.
With a strong team spirit, committed and talented individuals, GSS continues to position itself at the forefront of supporting Surbana Jurong Group's growth towards its SJ 2.0 aspirations.
