Technical Lead

We are seeking a talented Optical DWDM/OTN Automation Development & Testing Engineer to join our cutting-edge technology division. In this hybrid role, you will bridge the gap between software development and quality engineering. You will play a crucial role in developing automation frameworks, building testing tools/simulators, and executing automated test strategies using a mix of Java and Python to ensure the reliability, scalability, and performance of our optical communication systems.

Responsibilities

Design, develop, and maintain robust test automation frameworks, infrastructure, and internal tools using Java and Python, specifically tailored for Optical DWDM/OTN systems. Feature & Simulation Dev: Develop simulation tools, network element stubs, and mock environments in Java to mimic complex optical network behaviors, traffic patterns, and control plane protocols for comprehensive testing.

Test Automation Engineering: Write, review, and implement clean, scalable automated test scripts with a strong emphasis on ODU/OTU or lambda-level switching functionalities. Cross-Functional Collaboration: Partner with hardware, firmware, and software design teams to define architecture requirements, test strategies, and comprehensive test plans early in the development lifecycle.

Hardware Integration Testing: Configure, control, and automate operations for testing equipment (e.g., optical spectrum analyzers, power meters, traffic generators) using APIs, Java libraries, and Python scripts. End-to-End Validation: Perform system-level validation, including signal quality analysis, Bit Error Rate (BER) testing, and protocol compliance verification at the ODU/OTU or lambda level.

Triage & Debugging: Analyze complex automation failures, isolate root causes across software/hardware boundaries, and work closely with core engineering teams to fix bugs. CI/CD Integration: Integrate Java- and Python-based automated test suites into continuous integration and deployment (CI/CD) pipelines to enable continuous testing and rapid release cycles.

Requirements

Bachelor’s or Master’s degree in Computer Science, Electronics & Communications Engineering, IT, or a related technical field. Optical Domain Expertise: Strong foundational knowledge of Optical DWDM/OTN technologies, with in-depth understanding of ODU/OTU framing, multiplexing, and lambda-level switching concepts. Software Development Skills (Java & Python): Strong programming experience in Java (including Core Java, OOP concepts, multi-threading, concurrency, and data structures) for building simulation utilities or framework backends.

Proficiency in Python for test automation, script development, and rapid prototyping. Testing Methodologies: Proven experience in software/hardware testing life cycles, test case design, and building scalable automation frameworks (e.g., TestNG, JUnit, Py. Test, Robot Framework). Hands-on Hardware Experience: Direct experience interacting with lab equipment like optical spectrum analyzers, power meters, and network traffic generators (e.

g., Ixia, Viavi, Spirent) via automated scripts or APIs. DevOps & Build Tools: Familiarity with Git version control, build tools (e.g., Maven, Gradle), and CI/CD pipelines (e.g., Jenkins, GitLab CI). Soft Skills: Strong analytical, troubleshooting, and problem-solving skills, with the ability to work effectively in a fast-paced agile development environment.
