Software Integration Lead - 5G CORE

About the role

You will architect and own the end-to-end integration strategy that connects back-office business support systems with our 5G Core network over satellite and ground segments. You will define interface contracts, enforce standards, and act as the primary technical authority for all subscriber and business logic integrations. You will translate complex business requirements into robust, scalable integration patterns that work seamlessly across LEO space and terrestrial environments. You will lead the delivery of critical workflows such as SIM and eSIM provisioning, CRM synchronization, billing, charging, and device lifecycle management. You will partner closely with network, product, and operations teams to ensure reliability, security, and performance meet the highest standards. You will troubleshoot integration failures, drive root cause analysis, and implement monitoring that keeps the ecosystem observable and deterministic. You will mentor engineers on best practices for integration design and foster a culture of clarity and accountability. You will ensure that every integration touchpoint is documented, testable, and aligned with our mission to make connectivity from space universally accessible, secure, and actionable.
