The role of Software Development Test Engineer in Bangalore focuses on building robust, automated test frameworks for Cisco’s optical networking products, including DWDM, ROADM and optical line systems. The engineer will write Python‑based test scripts, develop unit and integration tests, and collaborate closely with product and hardware teams to validate software functionality against real‑world deployment scenarios. This position offers a hybrid work model, allowing candidates to work from the state‑of‑the‑art Cisco campus while also leveraging remote flexibility for focused development tasks.

Key responsibilities include

• Design, develop and maintain Python test automation suites for optical networking solutions.
• Create and execute functional, regression, performance and reliability test cases.
• Work with cross‑functional engineering teams to translate customer deployment requirements into test strategies.
• Debug and troubleshoot software defects on Linux platforms, providing clear root‑cause analysis.
• Participate in code reviews, ensuring adherence to secure coding standards and best practices.
• Contribute to continuous integration pipelines by integrating automated tests into CI/CD workflows.
• Monitor test execution metrics, triage incidents, and support post‑incident reviews.
• Document test plans, test cases, and results in a clear, reproducible manner.
• Mentor junior team members on test automation techniques and optical networking fundamentals.
• Estimate effort for test tasks, communicate progress and proactively address blockers.

The technical stack revolves around Python, pytest or unittest frameworks, Linux command‑line tools, Git for version control, and CI platforms such as Jenkins or GitLab. Knowledge of optical networking concepts—DWDM, ROADM, and optical line systems—is essential, as is familiarity with networking protocols and hardware interfaces. Candidates with exposure to Agile methodologies and test‑driven development will thrive.

Growth path for a Software Development Test Engineer at Cisco typically progresses from Engineer I to Engineer II, Senior Engineer, and eventually to Principal Engineer or Test Lead, with opportunities to move into product management or architecture roles.
