Senior RAN​/Cloud Engineer

Candidate will be required to work in Redmond WA and Nokia customer site full time.

• Test Strategy & Planning: Develop and implement detailed test plans, test cases, and test strategies for RAN features, including functional, performance, stability, and regression testing, specifically addressing cloud-native deployments and OAM aspects.
• Cloud OAM Validation: Design and execute tests to validate the OAM functionalities of cloud-native RAN components, including fault management, configuration management, performance management, security management, and lifecycle management (e.g., deployment, scaling, upgrades) in cloud environments.
• Test Automation: Drive the development and maintenance of automated test suites and frameworks using scripting languages (e.g., Python, Robot Framework) to enhance efficiency and coverage for both RAN and Cloud OAM testing.
• Troubleshooting & Analysis: Identify, analyze, and debug complex issues within RAN software and hardware, particularly those related to cloud infrastructure, virtualization, and OAM interactions, collaborating with development teams for resolution.
• Performance & Scalability Testing: Conduct performance, load, and stress testing for RAN elements deployed on cloud platforms, evaluating resource utilization, latency, and throughput under various conditions.
• Documentation & Reporting: Create clear and concise test reports, defect descriptions, and technical documentation, communicating findings to stakeholders.
• Continuous Improvement: Proactively identify areas for test process improvement, tool enhancement, and adoption of best practices in cloud-native testing.
• Collaboration: Work closely with R&D, product management, and customer support teams to ensure high-quality product delivery.

Education: Bachelor's or Master's degree in Electrical Engineering, Computer Science, Telecommunications, or related years of experience.

Experience: 5+ years of experience in RAN testing, with a significant portion focused on 4G/5G technologies.

• In-depth understanding of 4G (LTE) and 5G () RAN architectures, protocols (e.g., RRC, PDCP, RLC, MAC, PHY), and interfaces (e.g., F1, X2, Xn, S1, N2).
• Experience with RAN functional testing, performance testing, and system integration.
• Execution of test strategies, Report creation and review with Customer Team.
• Strong understanding of cloud-native principles, microservices architecture, and containerization (e.g., Docker, Kubernetes).
• Hands-on experience with cloud platforms (e.g., Open Stack, VMware, AWS, Azure, GCP) and virtualization technologies.
• Proficiency in OAM concepts and tools for cloud-based systems, including monitoring (e.g., Prometheus, Grafana), logging (e.g., ELK stack), orchestration (e.g., Helm, Ansible), and CI/CD pipelines.
• Familiarity with network function virtualization (NFV) and software-defined networking (SDN) concepts.

• Experience with test automation frameworks (e.g., Robot Framework, Pytest).
• Familiarity with version control systems (e.g., Git).
• Knowledge of networking fundamentals (TCP/IP, routing, switching).

• Excellent problem-solving and analytical skills.
• Strong communication and interpersonal skills, with the ability to work effectively in a global team environment.
• Ability to work independently and manage multiple priorities.

• Experience with Nokia RAN products.
• Certifications in cloud technologies (e.g., AWS Certified Solutions Architect, Kubernetes Administrator).
• Knowledge of security testing principles.
