Hi, I'm Peter, VP of Networks at Airalo!
Our team ensures customers have instant, smooth connectivity from the moment they purchase their plan to the moment they arrive at their destination. We go beyond standard mobile service, building innovative solutions that enhance the traveller experience. We're looking for curious engineers who want to design the future of global networks. Think outside the box, reverse-engineer solutions from ambitious product ideas, and help pave the way for Airalo's leadership as a global connectivity partner.
Airalo's fully remote Networks team is growing. You'll work on the systems and infrastructure that keep over 20 million travellers connected reliably and securely at global scale. Solve complex technical challenges, optimize processes, and experiment with better ways to keep the world connected.
As our Senior Network Solution Architect, you will be the primary designer of how our users consume services globally. You aren't just managing a single node; you are architecting the High-Level Design (HLD) for our Data, Voice (VoLTE/VoNR), and Messaging (SMSoIP) services. You will bridge the gap between business requirements and technical execution, ensuring our network remains robust as we scale our global traveler base.
Your main responsibilities will be:
- Own the HLD and LLD for Core Network services, ensuring seamless integration between the Packet Core (EPC/5GC) and IMS domains.
- Lead the technical rollout of VoLTE Roaming (S8HR) and SMSoIP strategies, ensuring high-quality voice and messaging services across diverse roaming partners.
- Design and optimise data session flows, including Local Breakout and Home Routed architectures to minimise latency for global users.
- Lead technical discussions with IPX/GRX providers and Equipment Vendors to secure the best architectural paths for our traffic.
- Act as the Subject Matter Expert for the transition from 4G to 5G Standalone (SA), focusing on the deployment of the Service-Based Architecture (SBA).
Bonus Points:
- Experience with Cloud Native Network Functions (CNF) and deploying core elements in AWS/GCP/Azure environments.
- Knowledge of 5G Slicing and how it applies to specialised data services.
- Previous experience in an MVNE/MVNO environment during a high-growth phase.
