Lead I - Software Testing- Python Automation + API testing

Role description

Job Description

• Design & Execute comprehensive test strategies covering functional, regression, integration, and end-to-end testing for microservices-based systems
• Performance & Load Testing design, develop, and execute performance test suites using Gatling and/or Locust to validate system behavior under high-throughput, high-concurrency conditions
• Automate build and maintain robust automated test frameworks using Python and PyTest, ensuring high coverage and fast feedback loops
• Understand the Product proactively learn functional and business domain knowledge to independently create meaningful, well-targeted test cases that go beyond surface-level validation
• Non-Functional Testing contribute to scalability, reliability, soak, and stress testing to ensure services meet production-grade SLAs
• API Testing validate RESTful APIs for correctness, error handling, data integrity, and contract compliance
• Debug & Investigate trace test failures across distributed services and cloud infrastructure; collaborate with developers on root cause analysis
• Collaborate work closely with developers, product owners, and cross-functional teams to define acceptance criteria, identify edge cases, and shift quality left
• CI/CD Integration integrate automated test suites into CI/CD pipelines for continuous quality validation
• Report & Communicate produce clear test reports, defect analyses, and quality metrics; flag risks early and advocate for quality across the team
• Document maintain test plans, test cases, and testing documentation to ensure traceability and knowledge sharing

Skill Required

• Professional experience in software testing / quality engineering, with a focus on testing scalable, distributed systems
• Strong hands-on experience with Python and the PyTest framework for test automation
• Practical experience with performance testing tools Gatling and/or Locust including test script development, execution, and results analysis
• Solid understanding of different types of testing: functional, regression, integration, end-to-end, smoke, sanity, performance, load, stress, and soak testing
• Experience testing RESTful APIs and microservices architectures
• Ability to quickly grasp functional and business domain knowledge and translate it into comprehensive, well-structured test cases
• Good debugging and analytical skills comfortable reading application logs, tracing failures across services, and providing clear defect reports with reproduction steps
• Familiarity with CI/CD pipelines and integrating automated tests into build and deployment workflows
• Experience with Git and version control workflows
• Basic understanding of cloud environments (AWS preferred e.g., EKS, S3, SQS/SNS, Lambda)
• Good communication skills with the ability to ask the right questions, clarify requirements, and collaborate effectively with developers and product stakeholders

Nice to Have

• Experience testing applications that integrate with search backends (Solr, Elasticsearch, or OpenSearch)
• Familiarity with Java and ability to read/understand Java-based microservice code
• Experience with contract testing (e.g., Pact) or API specification validation (OpenAPI/Swagger)
• Exposure to Bash scripting for test utilities and automation
• Familiarity with Docker and Kubernetes (EKS) for testing in containerized environments
• Experience with observability and monitoring tools (CloudWatch, Datadog, Splunk, Grafana) for correlating test results with system behaviuor
• Awareness of event-driven architectures and messaging systems (Kafka, SQS/SNS)
• Experience working in Agile/Scrum environments
• Exposure to accessibility testing or security testing fundamentals
• Experience collaborating with cross-functional or globally distributed teams
