Job description

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 Relic.
  • Qualifications :

  • 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.
