About This Role
- Own architecture, design, capacity planning, and performance of the 5G core, IMS voice/SMS services, and integration with Skylo’s NTN RAN.
- Lead core network vendor technical reviews and acceptance; design roaming/interconnect with mobile network partners and address NTN-specific network requirements.
- Set core network KPI frameworks and drive optimisation, incident root-cause analysis, technical validation, and engineering guidance as the network scales.
Minimum Requirements
- Work Experience Required: 15+ years in mobile core network engineering, design, or architecture; experience at an MNO or core network vendor is preferred.
- Deep hands-on experience with 5G Core SA and EPC, IMS call flows and services (SMS, VoLTE, VoNR), and relevant telecom protocols including NAS, GTP, PFCP, Diameter, SIP, and HTTP/2.
- Hands-on experience with cloud-native network functions and technologies such as Kubernetes, Docker, and AWS or GCP; demonstrated capacity planning, KPI definition, and performance optimisation experience.
- Location: Bangalore, India; onsite 3 days per week.
Ideal Candidate Profile
- A senior mobile-core architect with end-to-end expertise spanning 5GC/EPC, IMS, roaming/interconnect, vendor management, and production network performance.
- Has experience adapting core network architecture for satellite or other non-terrestrial connectivity; 3GPP Rel-17+ NTN experience is highly preferred.
- Likely to succeed in a technical-authority role that combines architecture and capacity decisions with lab validation, operational incident follow-through, and mentoring engineers.
