Senior Integration Engineer

## Join our Team About This Opportunity The networks powering 4G and 5G connectivity don't build themselves — and neither do the cloud-native platforms transforming how they run. As a Senior System Integrator specialising in Ericsson's Dual Mode Core, you'll be at the technical sharp end of some of the most complex and consequential deployments in the region. This is a hands-on leadership role. You'll own integration, deployment, migration, and troubleshooting across live Tier-1 operator environments — working at the intersection of traditional core networks and next-generation cloud-native infrastructure. If you thrive under pressure, take pride in technical precision, and want your work to directly shape how millions of people connect — this is your role. What You'll Do Lead Integration & Deployment: Drive installation, configuration, commissioning, and end-to-end validation of Ericsson DMC solutions across 4G and 5G Core networks. You'll ensure every deployment meets design standards and goes live with confidence. Own Cloud-Native Delivery: Deploy and manage DMC workloads on Ericsson's cloud platforms — onboarding cloud-native network functions, troubleshooting Kubernetes, storage, and networking layers, and leading migrations from virtualised to cloud-native infrastructure. Execute Upgrades & Lifecycle Management: Lead in-service software upgrades, transformation activities, and End-of-Maintenance replacements — validating service continuity every step of the way so the network never misses a beat. Drive Troubleshooting & Incident Recovery: When complex issues arise, you'll lead the technical investigation — analysing logs, traces, alarms, and performance data, working directly with Product Development Units to find root causes and stabilise critical services fast. Execute Change with Discipline: Own the implementation of approved Method of Procedures (MOPs), pre-checks, health checks, and post-validation activities. Rollback plans will always be ready. Nothing goes to production without your sign-off on readiness. Optimise & Automate: Analyse performance trends, support capacity planning, and continuously push for smarter ways of working — building scripts, leveraging CI/CD and GitOps frameworks, and reducing manual effort through automation. What You Bring Core Network Expertise • Deep knowledge of Ericsson Dual Mode Core (DMC) solutions. • Strong command of 4G EPC and 5G SA Core architectures, end-to-end service flows, and subscriber lifecycle management. • Solid understanding of signalling, policy control, charging, and subscriber data management. • Experience with high availability and geo-redundant network designs. Cloud & Linux • Hands-on experience with CNIS and cloud-native telecom deployments. • Linux system administration, shell scripting, Ansible, and Python. • CI/CD pipeline understanding and GitOps practices. Protocols & Interfaces • IP Networking, TCP/IP, Diameter, SCTP, HTTP/2, DNS, REST APIs — you know these cold. Experience • 8–12+ years in Telecom Core Network integration and support. • Proven track record in Tier-1 operator environments. • Strong background in cloud transformation, upgrades, migrations, and complex multi-domain troubleshooting.
