Optical Transmission SME

The Opportunity.

We're hiring an experienced
Optical Transmission SME / Fiber Optics Lead
to be the Manila-based POC for regional optical transport and transmission engineering across Southeast Asia. This role requires deep, hands-on mastery of
DWDM transmission systems
and
SDH/SONET
transport stacks, plus the ability to lead projects, manage vendor relationships (e.g., Ciena), and resolve complex production incidents quickly.

The Role.

Transmission Design & Architecture (Hands-On)

• Design and validate DWDM line systems and subsystems (e.g., transponders, mux/demux, OADM/ROADM, optical amplifiers, dispersion/power management).
• Specify and validate SDH/SONET hierarchy mapping (STMx / VC/AU/TU mappings) and service multiplexing.
• Define and validate protection schemes and resiliency: e.g., 1+1, 1:1, ring protection (MSP/SNCP), and relevant failover characteristics.
• Validate optical layer parameters and managem...
