Software Engineer in Test

Summary

At PLVision, we are driving the open networking transformation. We partner with top silicon vendors and telecom leaders to build custom, disaggregated network solutions using open-source technologies like SONiC, SAI, and DentOS. We are looking for an Automation Engineer to help us scale our quality infrastructure. In this role, you won’t just be executing tests; you will be architecting automation frameworks, writing Python code, and building the CI/CD pipelines that validate next-generation Network Operating Systems (NOS) across diverse hardware platforms.

Responsibilities

• Design & Architect: Build, scale, and maintain robust automated test environments and CI/CD pipelines to ensure continuous quality for cutting-edge open networking products
• Develop in Python: Write clean, maintainable Python code to engineer new automated test scripts, tools, and libraries that extend coverage for L2/L3 protocols and new NOS features
• Innovate Tooling: Architect internal tools and automation frameworks to streamline software builds, integration, and hardware-in-the-loop (HIL) testing
• Automate Execution: Automate comprehensive test suites for SONiC/SAI software across a variety of hardware platforms (switches, SmartNICs)
• Collaborate & Integrate: Partner closely with software engineers to translate product requirements into executable automation code and automated test strategies
• Analyze & Optimize: Integrate automated regression tests into continuous integration workflows, capturing actionable telemetry and logs to accelerate software debugging and performance optimization
• Troubleshoot Infrastructure: Act as a key technical resource to troubleshoot and resolve complex CI/CD, build dependency, and hardware/software integration issues

Requirements

• Automation Engineering: 3+ years of commercial experience as an Automation Engineer or SDET, with strong proficiency in Python programming
• Linux Expertise: Deep knowledge of Linux administration, shell scripting, and advanced system troubleshooting
• Networking Foundation: Solid understanding of computer networking, particularly L2/L3 protocol implementation and TCP socket programming
• Communication: Intermediate or higher technical English for effective collaboration in a global engineering environment

Would be a plus

• Familiarity with open networking ecosystems like SONiC (Software for Open Networking in the Cloud) or SAI (Switch Abstraction Interface)
• Experience building automation for Network Operating Systems (NOS)
• Hands-on experience with virtualization, Docker containers, and microservices architectures (highly relevant for cloud-native NOS like SONiC)
• Advanced understanding of the Linux networking stack (e.g., tc, iptables, netns)
• Proven expertise in designing and maintaining CI/CD pipelines (e.g., Jenkins, GitLab CI)
• Background in embedded systems, application development, or hardware integration
