Your Role:
As a QA Tester – Agentic Web Application, you will own hands-on functional, regression, integration, and end-to-end testing for a healthcare web application that integrates AI agents, APIs, databases, background workers, and external systems. You will help ensure application quality, identify defects before they reach customers, and provide reliable test coverage while the US engineering team is offline.

• Execute Test Plans: Create and maintain practical test plans, test cases, and regression checklists for new features, bug fixes, integrations, and production releases.

• Validate End-to-End Workflows: Test application functionality across browser interfaces, APIs, databases, webhooks, background workers, queues, and third-party integrations.

• Test AI and Voice Agents: Interact with voice-based AI agents through phone calls and evaluate their responses, tool usage, workflow execution, error handling, and ability to follow instructions across realistic scenarios.

• Develop Automated Tests: Create and maintain repeatable QA scripts and automated tests using Playwright, pytest, API testing tools, or comparable technologies, leveraging AI tools to improve testing efficiency and coverage.

• Investigate and Document Defects: Use browser developer tools, application logs, network requests, screenshots, and database records to identify root causes and produce clear, actionable bug reports.

• Validate Data Integrity and Integrations: Verify that patient and practice configurations, call records, appointments, transcripts, and job statuses remain consistent across connected systems.

• Test Edge Cases and Failure Scenarios: Evaluate authentication, permissions, duplicate requests, retries, timeouts, delayed webhooks, provider outages, and partial workflow failures.

• Maintain QA Documentation: Establish a practical testing framework, such as a daily test tracker with pass/fail indicators, and submit a written summary of testing results, outstanding defects, and risks before signing off.

What You Need:
Non-negotiables

• Prior professional experience in QA testing for production web applications, with strong functional, exploratory, and regression testing skills. This role requires an experienced QA professional who can work independently without junior-level training.

• Hands-on experience with test automation and writing QA testing scripts using Playwright, pytest, or comparable tools.

• Strong browser testing skills, including the ability to use browser developer tools to inspect network requests, API responses, errors, and application behavior.

• Excellent written communication skills and the ability to produce clear, concise, reproducible bug reports with expected versus actual results, supporting evidence, and severity.

• Demonstrated proficiency with AI tools such as ChatGPT, Codex, Claude Code, or Cursor to generate test cases, develop scripts, analyze logs, and support defect investigation.

• Near-conversational US English proficiency with clear, understandable speech to communicate effectively with voice-based AI agents through phone calls.

• Ability to reason across user interfaces, APIs, databases, and asynchronous processes rather than relying solely on visible browser behavior.

• Strong attention to detail, data integrity, privacy, permissions, and security in a healthcare-oriented application.

• Ability to work independently in a fully remote setup and provide consistent QA coverage during the US engineering team's off-hours.

Preferred skills/expertise

• Hands-on experience testing AI-driven applications, LLMs, conversational AI, voice agents, or tool-calling systems.

• Experience testing asynchronous workflows, message queues, background workers, webhooks, scheduled jobs, retries, and event-driven systems.

• SQL proficiency for validating application data and database states.

• Familiarity with Python, Flask, HTTP/REST APIs, PostgreSQL, SQLAlchemy, Redis, and automated testing frameworks.

• Experience with AWS services and CloudWatch logs, Docker, GitHub Actions, or similar deployment and monitoring tools.

• Exposure to healthcare technology, electronic health records (EHR), FHIR integrations, or other security- and privacy-sensitive applications.

• Experience with third-party integrations involving telephony, identity providers, CRM platforms, external APIs, and browser automation.

• Ability to troubleshoot flaky automated tests, improve regression coverage, and develop reusable test scenarios with AI-assisted workflows.
