Sr. Network Engineer, DFS – ()
Description
Role Purpose
The role of Senior Network Engineer (DFS) to design, implement, and manage the network infrastructure that underpins our DFS platform deployed. The role requires expertise in DFS transaction flows, security, reliability, and scalability, coupled with strong knowledge of Huawei network solutions and financial-grade networking best practices.
This engineer will play a critical role in ensuring secure, high-performance, and highly available connectivity across data centres, cloud, and service endpoints supporting our DFS ecosystem.
Key Responsibilities
Network Design & Architecture
· Design and optimize DFS network architecture across on-premises, cloud, and containerized microservice platforms.
· Ensure resilient connectivity for DFS transaction flows (USSD, mobile apps, agent networks, APIs, payment switches).
· Work closely with application/microservice teams to provide network-aware designs for containerized deployments.
DFS Infrastructure
· Implement and support Huawei core network elements powering DFS platforms (e.g., Huawei CBS, Wallet, Mobile Money, Payment Gateways).
· Configure and maintain Huawei firewalls, switches, load balancers, and SDN solutions in DFS contexts.
· Apply Huawei CloudCampus/Agile Controller/SR/Firewall capabilities for DFS infrastructure security and efficiency.
Performance & Monitoring
· Build network monitoring and observability dashboards for DFS transaction performance, latency, and throughput.
· Proactively troubleshoot and resolve network-related bottlenecks in DFS microservices and container environments.
· Conduct capacity planning to handle DFS transaction growth.
Security & Compliance
· Implement DFS security standards (PCI DSS, ISO 27001) with focus on data-in-motion encryption and secure channeling.
· Configure and maintain firewall rules, VPNs, and API gateway connectivity for DFS integrations with banks, telcos, and third parties.
· Enforce segmentation and zero-trust networking for microservices and APIs.
Collaboration & Leadership
· Work with DevOps, Application, and Security teams to integrate networking into CI/CD pipelines for DFS deployments.
· Mentor junior engineers and provide technical leadership for network operations in DFS projects.
· Contribute to DFS network roadmap and modernization initiatives.
Qualifications
Qualifications & Experience:
· Bachelor’s degree in computer science, Information Technology, Telecommunications, or related field.
· CCNP (Mandatory), ITIL v4 Foundation (Preferred), CCIE (Added Advantage), Security Certifications (e.g., CCSA, NSE, or Cisco Security).
· Huawei HCIE or HCNP in Routing & Switching, Security, or Cloud will be an added advantage.
· Minimum of 10+ years in IP Network operations, with at least 3+ years in a senior Engineering role handling complex enterprise network environments.
Skills & Competencies
· Deep hands-on experience managing large-scale enterprise networks, including Cisco SD-WAN, SD-Access, and Nexus-based Data Center switching fabrics.
· Strong understanding of Data Center Networks (DCN), high-availability architectures, virtualization layers, cabling standards, and critical infrastructure dependencies.
· Experience with enterprise-grade load balancers (e.g., F5, Citrix ADC) for application availability, SSL offloading, and traffic distribution in multi-tier environments.
· Exposure to cloud networking and connectivity models (e.g., ExpressRoute, VPN Gateway, VNET peering) in platforms like Microsoft Azure or AWS.
· Hands-on expertise with Huawei networking technologies: Huawei Firewalls (USG Series), Switches (CE/S Series), Routers (NE Series).
· Huawei Agile Controller, iMaster NCE, SD-WAN, and CloudCampus.
· Experience supporting containerized/microservice platforms (Kubernetes/OpenShift/AKS) with integrated networking.
· Strong background in network security, load balancing, HA, and failover in financial environments.
· Familiarity with integration across DFS partners (banks, telcos, aggregators).
