Overview
Drive the automation and DevOps infrastructure underpinning a lab-based 4G/5G cellular network system by engineering scalable frameworks, robust APIs, and seamless hardware integration. This role is central to enabling advanced testing, monitoring, and hardware access for network R&D, delivering the tools and interfaces that allow teams to interact programmatically and efficiently with cellular infrastructure.
Responsibilities
- Automate provisioning and management of radio access network (RAN) infrastructure in a research and development (R&D) lab setting.
- Develop, maintain, and optimize Python-based APIs and services for cellular network access, including base station (eNodeB/gNodeB) interactions.
- Integrate automation for hardware control and remote management of cellular network devices.
- Monitor, collect, and make available network metrics, KPIs, and health monitoring data via programmable interfaces for consumption by other teams.
- Troubleshoot and resolve issues related to network interfaces, connectivity, and automated workflows.
- Design and implement CI/CD pipelines and infrastructure-as-code solutions to streamline cellular testing and integration workflows.
Minimum Qualifications
- Deep proficiency in Python programming for API development and automation frameworks.
- Experience automating hardware and networking workflows, particularly with RAN equipment and cellular protocol stacks.
- Hands-on expertise developing and debugging RESTful APIs.
- Practical experience with Bash/Shell scripting for operational automation.
- Working knowledge of 4G/LTE and 5G NR cellular network architectures and protocols.
- Proven experience with CI/CD methodologies and tools (e.g., Jenkins, GitLab CI, or similar) in infrastructure-oriented environments.
- Understanding of containerized deployments (Docker, Kubernetes) for networking and automation use cases.
- Proven ability to monitor and troubleshoot lab-based network systems and interfaces.
Preferred Qualifications
- Experience integrating with eNodeB and gNodeB base stations for RAN control or test automation.
- Knowledge of cellular network KPIs, metrics extraction, and telemetry publishing best practices.
- Familiarity with software-defined networking (SDN) and network function virtualization (NFV) concepts.
- Prior work in an R&D environment developing tools for hardware-in-the-loop or network-in-the-loop testing.
