We are looking for a Senior Software Development Engineer in Test (SDET) to drive quality engineering and automation across Securonix products, including SIEM, ThreatQ (Threat Intelligence Platform/TIP), and associated cloud, microservices, data, and security capabilities.

Role Overview:

As a Senior SDET, you will design and build scalable automation solutions across API, UI, backend, integration, and end-to-end workflows. The ideal candidate will have strong programming skills in Python, hands-on experience with Pytest and Playwright, and a solid understanding of API and microservices testing. You will work closely with Engineering, Product, DevOps, and QA teams to embed quality throughout the software development lifecycle.

Key Responsibilities:

• Design, develop, and maintain scalable automation frameworks using Python and Pytest.
• Build and maintain modern UI and end-to-end automation using Playwright.
• Develop automated test suites for API, UI, backend, integration, regression, and end-to-end testing.
• Drive an API-first automation strategy for microservices and platform capabilities.
• Validate REST APIs, service-to-service integrations, authentication, data contracts, error handling, and distributed workflows.
• Validate data-processing pipelines and data integrity using Python, SQL, and API-based validation.
• Test complex workflows across Securonix products, including SIEM and ThreatQ/TIP.
• Develop reusable automation libraries, utilities, fixtures, test-data management, and reporting capabilities.
• Integrate automated tests into CI/CD pipelines and enable continuous testing.
• Analyze automation failures, application logs, API responses, and backend data to perform root-cause analysis.
• Participate in design and architecture discussions to improve testability, observability, reliability, and product quality.
• Identify regression risks and ensure appropriate automated coverage for new features and production defect fixes.
• Mentor QA/SDET engineers on automation design, coding standards, debugging, and testing best practices.
• Explore AI-assisted testing and automation to improve test coverage, productivity, and defect detection.

Required Technical Skills:

• 5–8 years of experience in Quality Engineering, Test Automation, or SDET roles.
• Strong programming experience in Python.
• Strong hands-on experience with Pytest, including fixtures, parametrization, reusable libraries, and framework design.
• Strong hands-on experience with Playwright for UI and end-to-end automation.
• Strong experience in REST API automation and testing.
• Experience designing or contributing to scalable automation frameworks—not only individual test scripts.
• Strong understanding of microservices and distributed architectures.
• Experience with SQL and backend/data validation.
• Experience testing complex integration and end-to-end workflows.
• Experience integrating automation with CI/CD systems such as Jenkins, Harness, GitHub Actions, or GitLab CI.
• Good understanding of Git, Linux/Unix, debugging, logging, and defect-management tools such as JIRA.
• Strong understanding of software-testing principles, test-design techniques, regression strategies, and Agile development practices.

What We're Looking For:

• Strong problem-solving, troubleshooting, and debugging skills.
• Ability to take end-to-end ownership of quality for a feature or product area.
• Ability to understand complex product architectures and identify appropriate testing strategies.
• Strong collaboration skills for working with Engineering, Product, DevOps, and other QA/SDET teams.
• Passion for automation, cybersecurity, AI, and modern quality engineering.
