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 : BigQuery/Snowflake/Redshift/PostgreSQL

- Observability : Prometheus, Grafana, Datadog/New Relic

Qualifications :

- Bachelors in CS/IT or equivalent experience.

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.
