• A high degree of ownership and the opportunity to shape how things are done.
• A modern, AI-first working environment with a proprietary tech stack.
• A profitable, bootstrapped organization serving more than 200 clients.

3. Final decision.

Feedback is usually provided within one to two business days.

Who we are?

We're a fast-growing telehealth product launched in 2025, backed by an established e-commerce company with roots going back to 2012. We're focused on the US market, building a platform that connects patients with doctors for real medical care: think weight-loss treatment, prescriptions, and insurance-covered telehealth visits, all wrapped in a strict, HIPAA-conscious environment. Our user base is growing fast, and our team is remote-first across multiple countries. 

Role Overview

As a QA Engineer, you will ensure high product quality across our e-commerce and healthcare platform. This is a hybrid role (approx. 70% Manual / 30% Automation). You will be primarily responsible for hands-on functional, regression, and exploratory testing of complex business logic and new features, while also contributing to and maintaining our UI and API automation suite using Playwright and TypeScript.

You'll work with a stack that includes Magento 2, Python microservices, and ReactJS on the product side, Playwright/TypeScript for automation, and AWS/GitHub Actions for CI/CD — using AI-assisted testing as part of daily practice.

What you'll do:

• Maintain and expand automated test coverage using Playwright and TypeScript for critical regression scenarios.
• Leverage AI tools to accelerate test case design, documentation, test data generation, and automation script creation.
• Analyze product requirements early to identify edge cases, logic gaps, and potential risks before development begins.
• Manage test documentation, track tasks, and write clear, well-structured bug reports in Jira and Confluence.
• Monitor CI/CD execution results and flag pipeline stability or test flakiness issues to the team.

Job requirements

• 2+ years of commercial experience in manual Web testing (functional, regression, and exploratory testing of complex business logic).
• 1+ years of hands-on experience contributing to UI or API automation using Playwright and TypeScript (familiarity with POM and clean code principles).
• Practical understanding of e-commerce logic: order lifecycles, shopping cart mechanics, checkout, and payment flows.
• Experience testing REST/GraphQL APIs (Postman/DevTools) and writing SQL (MySQL) queries for verification and test setup.
• Familiarity with Web fundamentals (HTML/CSS, DevTools, Charles/Fiddler proxy tools) and practical Git/GitFlow experience.
• AI-assisted engineering: practical ability to use AI tools (ChatGPT, Claude, Gemini or others) to speed up test design, debugging, reporting and script writing, while critically validating output.
• Soft skills: strong proactivity, analytical mindset, customer-centric approach, and clear communication skills.
• Intermediate English level or higher for daily communication and documentation.

Bonus points

• Experience testing healthcare-related products, medical platforms, or HIPAA/EHR workflows.
• Hands-on experience with the Magento 2 platform.
• Experience testing payment integrations and subscription lifecycles (recurring billing, cancellations).
• Experience with CI/CD pipelines (GitHub Actions, Jenkins) or Docker.
