QA Engineer

QA Engineer responsible for both manual and automation testing across web, APIs, and data platforms. The role involves designing, executing, and maintaining test assets across the SDLC/STLC, with a focus on Selenium WebDriver automation using Java, modern Java microservices (Spring Boot), and data engineering workloads (batch/streaming).

Responsibilities
Analyze requirements, define test strategy, and create detailed test plans and test cases.
Execute manual functional, regression, UI, cross-browser, and exploratory tests.
Design, develop, and maintain Selenium WebDriver automation frameworks in Java (e.g., POM, data-driven).
Build and maintain reliable, reusable, and parameterized test scripts; prioritize and optimize test coverage.
Integrate automated tests with CI/CD pipelines (e.g., Jenkins/GitHub Actions) and report results.
Log, track, and validate defects; collaborate with developers for quick resolution.
Perform API testing (Postman/RestAssured) and database validations using SQL.
Prepare and manage test data and environments; ensure traceability to requirements.
Contribute to sprint ceremonies; provide clear test metrics and quality risks.
Test Java microservices and distributed systems: REST endpoints, messaging flows and event- driven architectures (e.g., Kafka/RabbitMQ).
Validate service contracts and schemas (OpenAPI/Swagger, JSON Schema, Avro/Protobuf) including backward/forward compatibility.
Design tests for distributed concerns: idempotency, retries/backoff, eventual consistency, saga/transaction flows, time-based logic.
Plan and execute API and service performance tests using JMeter to baseline and regressions
Basic security testing of auth flows (OAuth2/OIDC)

Required Skills
Strong understanding of SDLC and STLC, test design techniques and risk-based testing.
Proficiency in creating and executing test cases and converting them into automated suites.
API automation frameworks using RestAssured
Mobile testing: Appium (Android/iOS), device farms (BrowserStack, Sauce Labs, AWS Device Farm)
Hands-on with Selenium WebDriver and Java, including locators, waits, assertions, and test design patterns.
Experience with TestNG or JUnit, Maven/Gradle, and Git.
Working knowledge of SQL for data setup and verification.
Comfortable with browser dev tools, cross-browser testing, and basic performance checks.
Experience with test management and defect tracking tools (e.g., Jira, TestRail)
Strong debugging, documentation, and communication skills.
Java 11+ (preferably 17), Spring Boot, REST, OpenAPI/Swagger
Testing messaging and event-driven systems: Kafka (topics, partitions, consumer groups, exactly- once/at-least-once)
Containerization and environments: Docker, basic Kubernetes concepts; ephemeral dependencies with Testcontainers
Observability: logs/metrics/traces using ELK/EFK, Prometheus/Grafana, OpenTelemetry; ability to assert telemetry in tests.
Performance and reliability testing: JMeter or Gatling; basics of chaos/resilience testing.
Cloud fundamentals (AWS/GCP/Azure) for QA: object storage (S3/GCS), managed DBs/warehouses (RDS/BigQuery/Redshift/Snowflake), messaging (SQS/Pub/Sub), and secrets/config.
Security basics: testing OAuth2/OIDC, JWTs, and role-based access; understanding of OWASP Top 10 for APIs.
Familiarity with CI/CD tools (e.g., Jenkins, GitHub Actions) and artifact management.
Experience working in Agile/Scrum environments.

Nice to Have
Create mocks/stubs and isolated environments using WireMock, Testcontainers, and LocalStack; use contract testing (e.g., Pact).
Validate data pipelines: ingestion, transformation, and consumption across batch/streaming (e.g.,Kafka Spark/Airflow); implement data quality checks and reconciliation.
Strong in SQL; ETL/ELT concepts; batch/stream processing (Spark/Flink/Beam); orchestration (Airflow) or transformation (dbt)
BDD frameworks and practices: Cucumber (Gherkin); living documentation and collaboration with product/BA.

Qualifications
Bachelors degree in Engineering or related field (or equivalent experience)
4-8 years of professional QA experience across manual and automation testing
Proven experience building and maintaining Selenium + Java test frameworks.
Nice to have experience testing data pipelines and ensuring data quality in batch/streaming
contexts.
