Key skills for this role
We are seeking a high-performing Network Architecture Manager to lead the strategic evolution, capacity engineering, and resilient design of Holafly’s core telecom network architecture as we transition from vendor to increased control and ownership.
In this role, you will act as the key owner of Holafly’s core topology and end-to-end network performance. You will work in close partnership with our core network provider (our primary core network provider) to map out the current network footprint, identify capacity constraints, remediate performance pinch points, and enforce non-negotiable standards for network availability and fault tolerance.
Please note, this is not a people manager role.
Holafly is a high-growth scale-up revolutionizing global connectivity for travelers and businesses worldwide. By providing seamless travel eSIM solutions across 200+ destinations, Holafly empowers millions of users to stay connected instantly without roaming friction.
As traffic scales globally, maintaining an agile, high-capacity, and rock-solid core mobile network infrastructure is essential to our user experience.

Audit & Topology Mapping: Deeply map and document Holafly’s current end-to-end core network layout, covering packet core components (PGW/UPF, SMF, MME/AMF), roaming interfaces (S8/N9, GRX/IPX transit), and routing paths.
Provider Collaboration (Core Network Provider): Serve as the primary technical point of contact and architectural authority with our core network provider. Align on technical roadmaps, platform upgrades, feature releases, and SLA/SLO enforcement for core network functions.
Constraint & Bottleneck Identification: Monitor traffic distribution, data throughput, signaling load, and latency metrics across global regions to proactively flag network pinch points and hardware/bandwidth limits.
Remediation & Performance Optimization: Architect and deploy technical fixes for identified capacity bottlenecks, optimizing packet processing, session setup times, and IP routing pathways across international nodes.
Predictive Capacity Modeling: Develop data-driven capacity forecasts based on subscriber growth, peak travel seasons, and dynamic regional demand surges.
High Availability Design: Implement geo-redundancy, active-active failover mechanisms, and disaster recovery strategies across all core network nodes and interconnects.
Quality of Service (QoS) & Routing: Optimize QoS profiles, APN configurations, and dynamic routing protocols (BGP/MPLS) to maintain high throughput and ultra-low latency for travelers across diverse host MNO networks.
Incident Analysis & Escalation: with Service management on root cause analysis (RCA) for high-severity core network outages or degradation events in coordination with our core network provider, implementing preventive architectural changes.
Vendor & Interconnect Management: Collaborate with wholesale IPX carriers, clearinghouses, core vendor and MNO partners to eliminate single points of failure (SPOFs) in roaming paths.
3GPP Standards Evolution: Track advancements in 5G SA/NSA, eSIM profile management (eUICC/RSP), and Cloud-Native Core functions to continuously modernize Holafly’s architecture.
Exposure to cloud-native telecom architectures (AWS/GCP/Azure deployments, Kubernetes, NFV/VNF orchestration).
Direct experience with eSIM architecture (GSMA RSP standards, SM-DP+, SM-DS).
Professional fluency in Spanish (given partner/vendor dynamics with JSC Ingenium).
Provides international eSIM cards for mobile data connectivity while traveling.
