About the role

Key responsibilities & impact

Test Automation Design, build, and maintain the test automation framework from scratch - Python-based, covering API, integration, and end-to-end tests.
Establish patterns and conventions the engineering team builds on as the codebase grows.
Maintain test suites that are fast, reliable, and genuinely useful - flaky tests are a bug.
Data Validation Own test coverage for data transformation logic - verify correctness of outputs, edge case handling, schema validation, and data integrity across pipeline stages.
Design test strategies for data integration scenarios - source-to-destination data flows, transformation previews vs. execution results, and reconciliation checks.
Build test data management practices: repeatable fixtures, realistic financial data scenarios, and edge case libraries.
API & Workflow Testing Build and maintain comprehensive API test suites for REST and GraphQL endpoints.
Design test strategies for Temporal-orchestrated workflows - long-running processes, retry logic, fault tolerance, timeout handling, and idempotency verification.
Collaborate with backend engineers on testability requirements in new feature design.
CI/CD Integration Ensure all automated tests run in the CI/CD pipeline; work with the Cloud Engineer to integrate quality gates into deployment workflows.
Define test coverage thresholds and quality gates that block bad deployments without blocking good ones.
Defect Management & Quality Culture Conduct Blackbox Testing, Fault injection, Performance testing etc.
Identify, document, and track defects with clear reproduction steps and business impact.
Work closely with engineers on root cause analysis and regression prevention.
Advocate for testability in design reviews and code reviews.
Help engineers write better unit tests; review test quality alongside code quality.

Requirements

What you’ll need

5+ years QA or test engineering experience in a SaaS environment
Has built or significantly extended a test automation framework, not just run existing tests
Python-based test automation - Pytest, Playwright, or equivalent; manual-only QA is a disqualifier for this role
API testing - proficiency testing REST and/or GraphQL APIs, not just UI-layer testing
Data validation - has tested data pipelines, transformation logic, or systems where data correctness and integrity are the primary quality criterion
CI/CD integration - tests live in the pipeline; understands how to balance test confidence with pipeline speed
Active user of AI coding assistants in daily workflow.
Nice to Have: Experience testing workflow orchestration systems - Temporal, Airflow, Prefect, or similar.
Financial services or compliance-sensitive testing background.
Performance and load testing experience.
Contract testing (Pact or similar) for service boundaries.
Data engineering familiarity - understanding of ETL/ELT patterns aids in writing effective data validation tests.
Playwright for UI-level end-to-end testing.
