• Create and maintain documentation of the current end-to-end core network structure, including packet core elements, roaming interfaces, and routing paths.

• Act as the primary technical liaison and architectural authority with the core network provider.

• Coordinate on technical roadmaps, platform upgrades, feature releases, and enforcement of SLA/SLO.

• Analyze traffic distribution, data throughput, signaling load, and latency metrics to pinpoint network bottlenecks and hardware or bandwidth constraints.

• Design and implement solutions for capacity challenges, enhancing packet processing, session initiation times, and IP routing pathways.

• Generate data-driven capacity forecasts based on subscriber growth, peak travel seasons, and regional demand spikes.

• Establish geo-redundancy, active-active failover, and disaster recovery protocols.

• Fine-tune QoS profiles, APN setups, and BGP/MPLS routing protocols.

• Perform root cause analysis for significant outages or performance degradation events and make preventive architectural modifications.

• Collaborate with wholesale IPX carriers, clearinghouses, core vendors, and MNO partners to eliminate vulnerabilities.

• Keep abreast of 5G, eSIM, and cloud-native core standards to modernize Holafly’s architecture.

⛳️ Requirements

• Over 6 years of experience in mobile network architecture, core network engineering (EPC/5GC), or network strategy within an MNO, MVNO, or MVNE setting.

• Extensive hands-on experience with 3GPP LTE/5G core architectures, including MME, HSS, PGW, PCRF, AMF, UPF, and SMF.

• Familiarity with roaming protocols such as S6a, S8, GTP-C/U, Diameter, and SIP.

• Understanding of IPX interconnects.

• Experience collaborating closely with core platform vendors and cloud-native or virtualized MVNE platforms.
