Harmony Data Integration Technologies

Description :Were hiring a Senior QA Engineer who can own test automation across data/ETL pipelines, APIs, and web frontends. Youll design robust QA strategies, build CI/CD-native test suites, drive performance/load testing, and turn system requirements into executable, measurable test plans.What will you do :ETL/Data Quality Automation :- Design and automate tests for ingestion, transformation, and loading (schema checks, constraints, null/dup checks, reconciliation, row/column-level validation, business rule assertions).- Implement data contract and data lineage test coverage; ensure CDC/merge logic and dedup rules are verified.- Add data checks to orchestration (e.g., Airflow/Prefect/Cloud Composer) and block bad data from promotion.API & Frontend Test Automation :- Build end-to-end, integration, contract, and regression suites for REST/GraphQL services.- Create UI automation for critical user journeys; stabilize flaky tests with good wait/retry design.Performance/Load Testing :- Establish load, stress, soak, and breakpoint tests for APIs and web apps; define SLAs/SLOs and capacity baselines.Automate performance tests in CI and publish trend dashboards.CI/CD & Quality Gates :- Integrate tests into CI/CD (pre-merge, nightly, release) with quality gates, artifacting, and environment provisioning.- Build disposable test environments using containers and IaC; seed synthetic datasets for deterministic runs.Test Strategy & Documentation :- Turn PRDs/BRDs into detailed test plans, risk matrices, and traceability matrices.- Champion shift-left, code reviews for testability, and quality as code.Monitoring & Incident Support :- Instrument quality KPIs; collaborate on root-cause analysis; prevent regressions with guardrail tests.Must-have skills :- ETL/Data QA : Strong experience validating data pipelines/warehouses (e.g., BigQuery/Snowflake/Redshift/PostgreSQL), reconciliation at scale, partitioning/windowing awareness, and SQL proficiency.- Automation : Hands-on with Python/TypeScript/Java for test frameworks; solid patterns (fixtures, page objects, data builders).- API Testing : Postman/Newman, REST Assured, Pact or equivalent for contract testing.- UI Testing : Playwright or Cypress (preferred) for stable, parallelizable suites.- Performance Testing : k6 / JMeter / Locust; interpreting p95/p99, throughput, saturation; correlation with APM metrics.- CI/CD : GitHub Actions / GitLab CI / Jenkins; branching, artifacts, caching, matrix builds; gating policies.- Data Testing Frameworks : Great Expectations / Soda Core / dbt tests; schema diffs, expectations as code.- Cloud & Containers : Docker; working knowledge of Kubernetes-based ephemeral test envs.- Observability : Using Prometheus/Grafana/New Relic/Datadog to tie test results to runtime telemetry.Nice-to-have :- Orchestrators (Airflow/Prefect), CDC tools (Debezium), ELT (Airbyte/Fivetran), transformation (dbt/Spark/Dataflow).- IaC (Terraform), secrets management, feature flags.- Security testing exposure (OWASP ZAP, SAST/DAST), basic vuln triage.- Experience with data privacy and compliance test considerations.- Experience building synthetic data generators and golden datasets.Tools you might use here :- Data/ETL : SQL, dbt, Great Expectations/Soda, Airflow/Prefect- API/UI : Playwright/Cypress, Postman/Newman, REST Assured, Pact- Performance : k6, JMeter, Locust- CI/CD : GitHub Actions/GitLab CI/Jenkins, Docker, Terraform- Analytics/Stores : Observability : Prometheus, Grafana, Datadog/New RelicQualifications :- Bachelors in CS/IT or equivalent experience.- 6+ years in QA with at least 3 years in data/ETL test automation and 2+ years in performance testing.- Proven experience integrating tests into CI/CD and scaling suites for speed and reliability.- Excellent communication; comfortable driving quality across engineering, data, and product teams.Location : Mohali, Punjab (ref:hirist.tech)
