About the Role

We are looking for a quality-driven Engineer Tester to join our engineering team. You will ensure the reliability, performance, and correctness of cloud-native services that process large volumes of data to deliver fast, accurate results. You will design and accomplish both functional and non-functional testing strategies, working with developers and product owners to understand the product and identify quality risks.

This is an excellent opportunity for a testing professional who is passionate about automation, performance engineering, and building quality into every stage of the development lifecycle.

What You'll Do

• Design & Implement comprehensive test strategies covering functional, regression, integration, and end-to-end testing for microservices-based systems
• Performance & Load Testing — design, and implement performance test suites using Gatling and Locust to validate system behavior under high-throughput, high-concurrency conditions
• Automate — build automated test frameworks using Python and PyTest, ensuring high coverage and fast feedback loops
• Understand the Product — learn functional 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 Service level agreements
• 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 with developers, product owners, and teams to define acceptance criteria, identify edge cases, and shift quality left
• CI/CD Integration — integrate automated test suites into CI/CD pipelines for 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
• Reporting - You will report to an Engineering Manager.

• 2+ years of professional experience in software testing / quality engineering, with a focus on testing scalable, distributed systems
• Hands-on experience with Python and the PyTest framework for test automation
• Practical experience with performance testing tools — Gatling and Locust — including test script development, and results analysis
• Experience with 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
• Functional domain knowledge and translate it into comprehensive, well-structured test cases
• Good debugging and — 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
• Experience with cloud environments (AWS preferred — e.g., EKS, S3, SQS/SNS, Lambda)
• With the ability to ask the right questions, clarify requirements, and collaborate with developers and product partners

Nice to Have

• Experience testing applications that integrate with backend services (Java Spring Boot, .NET Services, or NoSql DBs)
• Familiarity with dotNet / Java and ability to read/understand .NET-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, and Kibana) for correlating test results with system behavior
• Awareness of event-driven architectures and messaging systems (Kafka, SQS/SNS)
• Experience with test management tools (e.g., Zephyr, TestRail, or Xray)
• Experience working in Agile/Scrum environments
• Exposure to accessibility testing or security testing fundamentals
• Experience collaborating with globally distributed teams
