About this opportunity:
We are looking for a Senior Solution Integrator with strong expertise in Ericsson Charging solutions to drive end-to-end integration, configuration, deployment, and verification activities. You will bridge solution design and execution, ensuring customer requirements are implemented with high quality, efficiency, and compliance across all environments.
You will work closely with architects, developers, testers, and customer stakeholders to deliver robust, scalable, and high-performance charging solutions.
What you will do:
-
Ability to work as technical lead/SSI in customer projects: requirements clarification, solution design, LLD creation, and technical risk assessment for charging solutions.
-
Comfortable working in agile and global delivery setups and continuous competence development in EC.
-
Design, implement and verify product and charging configurations (offers, balances, rules) needed to support B2C, B2B and B2X monetization scenarios.
-
Drive delivery activities end to end: installation, configuration, upgrades, migrations and customer acceptance.
-
Analyse customer requirements and translate them into clear, executable technical implementation steps.
-
Configure and secure northbound and southbound interfaces (SBI/HTTP2, Diameter Gy/Ro, REST/JSON, TLS, certificates) and validate end-to-end charging flows for voice, data, messaging, 5G and IoT.
-
Contribute to CI/CD pipelines and automated verification, including maiden installations, upgrades and regression testing using Ericsson frameworks (e.g., GitOps, ESSVT).
-
Collaborate closely with solution architects, project managers, security, operations and customer technical teams in design reviews, integration workshops and acceptance cycles.
-
Troubleshoot and perform root-cause analysis using logs, traces and metrics, driving defect resolution with R&D, product teams and customer operations.
The skills you bring:
-
Strong, hands-on experience in Ericsson Charging and CBEV (or similar OCS/CCS platforms), including online/offline charging, CHF, access functions.
-
Solid background in charging/business configuration, including rating and balance management, and offer setup and lifecycle management.
-
Practical experience with cloud-native platforms and infrastructure – containers, Kubernetes, AWS, OpenShift, SDI, CEPH or similar technologies.
-
Good proficiency in Linux, Python and shell scripting, and working comfortably in Kubernetes and containerized environments.
-
Experience working with databases and data platforms such as Oracle TimesTen, Cassandra and OpenSearch, data analytics and reporting.
-
Deep expertise in integration and interfaces – Diameter (Gy/Gx/Ro/Rf) aligned with 3GPP specifications, HTTP/2-based SBI, REST/JSON APIs and Kafka-based event streaming.
-
Solid understanding of security including TLS, certificates and role-based access control.
-
Proven experience working in agile delivery models, collaborating across multi-disciplinary and distributed teams.
-
Excellent analysis, debugging and problem-solving skills, with a structured approach to incidents, impact assessment and communication to internal and external stakeholders.
-
Clear and confident communicator in English, able to explain complex topics and produce high-quality documentation and presentations.
-
Hands-on experience with 4G/5G charging use cases, including Monetize 5G Services (EC), 5G offline CDRs and real-time monetization scenarios for B2C, B2B and IoT.
