Routing Engineering: Design and implement advanced BGP policies (path selection, community strings, filtering) to optimize multihoming and peering traffic across multiple IXPs.
MPLS and VPNs: Design, configure and maintain the MPLS core, including LDP/RSVP-TE and the deployment of L3 VPN services (VRF/M-BGP) and L2VPNs (VPLS/VPWS) for enterprise customers.
Optimization and QoS: Perform Traffic Engineering (TE) using RSVP-TE to ensure deterministic paths and apply QoS policies (DiffServ over MPLS) to prioritize critical services (Voice and Video).
Resilience: Implement high-availability and fast-convergence mechanisms such as BFD (Bidirectional Forwarding Detection) and MPLS FRR (Fast Reroute), targeting maximum SLAs (five nines).
Edge Technologies: Manage edge routers (Provider Edge
PE) and Carrier-Grade NAT (CGN) solutions and design IPv6 transition strategies (Dual Stack or DS-Lite).
Level 3 Troubleshooting: Lead resolution of complex incidents involving packet loss, microbursts, high latency and protocol failures (BGP session flapping, OSPF/IS-IS adjacency issues).

Bachelor’s degree in Electronic Engineering, Telecommunications, Information Technology or related fields;
External Routing: BGP (Border Gateway Protocol); strong command of iBGP, eBGP, route reflectors (RRs), advanced path selection policies, attribute manipulation (AS_PATH prepending, MED, local preference) and use of community strings.
MPLS Core: Proven experience with MPLS and VPNs, including LDP and RSVP-TE. Configuration and operation of L3 VPNs (M-BGP and VRFs) and L2VPNs (VPLS, VPWS or Ethernet VPN
EVPN).
Internal Routing: IGPs (OSPF or IS-IS); proficiency in designing hierarchical area topologies, metric optimization and ensuring fast convergence. Preferably with IS-IS experience.
High Availability, Resilience and Convergence: Practical knowledge of MPLS FRR, BFD and use of Non-Stop Routing (NSR) or Graceful Restart (GR).
Hardware: Carrier-grade routers; hands-on configuration and CLI experience on high-capacity routing platforms (e.g., Cisco NCS/ASR series, Juniper MX Series, or Huawei/Nokia platforms).
Addressing: IPv4 and IPv6; scalable addressing planning. Knowledge of IPv6 transition strategies (e.g., Dual Stack, DS-Lite, NAT444).
QoS and TE: Quality of Service; configuration of DiffServ models over MPLS, policing, shaping and traffic classification for SLA-driven services.
