Senior Engineer - Core Wireless (5G Core - Java)

As a Principal Engineer, you will be responsible for defining and driving the technical vision across projects, influencing architecture and engineering practices to align with organizational goals. You'll provide expert guidance, mentor senior engineers, and lead the development of scalable, high-impact solutions. Our team of architects and developers develops comprehensive Mobile Packet Core solutions that support both 4G LTE and 5G NR (New Radio) technologies. This includes the development of key components such as the Serving Gateway (SGW), PDN Gateway (PGW), and the User Plane Function (UPF) for 4G, as well as the Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF) for 5G. We design our solutions with a cloud-native approach, leveraging containerization, microservices, and orchestration technologies to ensure seamless scalability and manageability in dynamic cloud environments. Our MPC solutions are built with high availability in mind, incorporating redundant components and failover mechanisms to ensure continuous operation and minimal service disruption. Focusing on optimizing performance to handle telco-scale traffic loads, ensuring low latency and high throughput to meet the demanding requirements of modern mobile networks. Our solutions are designed to scale elastically, accommodating varying traffic loads and network demands efficiently, ensuring operators can adapt to changing conditions without compromising service quality. Implementing advanced load balancing techniques to distribute traffic evenly across network resources, enhancing both performance and reliability. We stay at the forefront of technological advancements, integrating emerging technologies such as Network Function Virtualization (NFV) and Software-Defined Networking (SDN) to enhance our solutions. Ensuring that our Mobile Packet Core solutions are interoperable with existing network elements and can be seamlessly integrated into diverse network environments. Working closely with clients to understand their unique requirements and tailor our solutions to meet their specific needs. Providing comprehensive support and training to help clients effectively deploy, manage, and optimize our Mobile Packet Core solutions.
