Overview: Quality and Test Automation
The Automation QA Engineer is vital for ensuring the reliability, performance, and correctness of our entire supply chain e-commerce platform. You will be responsible for designing, developing, and maintaining comprehensive automated test suites across the e-commerce user interface, complex internal business workflows (MES, WMS, OMS), and the logic governing our next-generation AI agents.
Internship Details
Duration: 3 months
Start Date: Immediate
Location: Remote
Stipend: None initially. Based on your first-quarter performance, you may be offered a paid full-time opportunity, or even be absorbed directly by the client as an FTE.
Key Responsibilities & Core Projects
You will embed quality assurance directly into the development and deployment lifecycle, serving as the gatekeeper for production releases.
- Test Suite Development: Develop and maintain robust, end-to-end automated test suites covering critical e-commerce flows (catalog navigation, checkout, payments, invoicing) and complex internal tool workflows (OMS/WMS operations).
- Quality Gates (CI/CD): Integrate automated test suites into the CI/CD pipeline (managed via Makefile) to enforce quality gates, ensuring no regressions are introduced and the platform adheres to performance standards before deployment.
- Performance & Load Testing: Implement and execute performance testing and load testing protocols to validate the scalability and resilience of the NestJS modular monolith, especially for high-traffic scenarios and intensive SCM transactions.
- API Integration Testing: Design and execute automated tests for API integrations between the core supply chain modules (e.g., testing the data contract integrity between WMS and OMS) and external payment services.
- Test Data Management: Create and maintain reliable test data factories to simulate complex multi-tenant and domain-specific scenarios (e.g., various HS codes, tenant feature flags).
- Regression Management: Continuously maintain and optimize the regression test suite to provide fast, reliable feedback to development teams operating within the Monorepo structure.
Required Technologies & Tools
Candidates must possess strong expertise in automated testing frameworks, CI/CD integration, and performance validation:
- Automation Frameworks: Experience selecting, building, and maintaining E2E (e.g., Playwright, Cypress) and API testing frameworks.
- Programming: Strong proficiency in TypeScript and Node.js for writing high-quality, maintainable test code.
- Performance/Load: Experience with tools for performance and load testing (e.g., JMeter, K6).
- CI/CD: Practical experience integrating tests into automated pipelines and working within a Monorepo environment.
- Data & Database: Ability to query PostgreSQL 15 directly to validate data integrity.
AI Agent Focus
You will be responsible for validating the behavior and accuracy of our AI systems.
- Agent Behavior Testing: Develop tests to validate the deterministic and non-deterministic behaviors of AI agents, ensuring they accurately process inputs, access data securely, and perform their intended functions (e.g., workflow optimization, customer support responses).
- Integration Validation: Verify the quality of data retrieval and the security of the API layers connecting AI agents (using LangChain/LlamaIndex) to the core WMS/OMS data.
Success Metrics & Career Path
Performance will be measured by:
- Test Coverage: Measurable increase in automated functional and regression test coverage across critical application paths.
- Defect Escape Rate: Reduction in the number of critical and high-severity defects escaping to production.
- Pipeline Reliability: Maintenance of stable, non-flaky test runs within the CI/CD pipeline.
Mentorship Structure: Reports to the Technical Architect or Engineering Lead, working directly with development teams across the Catalog, OMS, and WMS modules.
