Senior QA Engineer, Horizons

About The Team:

As a fundamental part of CookUnity’s platform, Horizon enables different business models, subscription plans, and order management, ensuring a seamless experience for all users. The Full Stack team is responsible for building and maintaining end-to-end solutions that bridge the gap between an intuitive frontend experience and a robust, scalable backend.

The team is responsible for two key areas:

1. Developing and Optimizing Subscription and Order Experiences: Full Stack engineers ensure that users can explore, manage, and subscribe to different plans effortlessly while maintaining a seamless order creation and management experience. This involves working on frontend interfaces, enhancing UI/UX, and optimizing interactions with backend services to improve engagement and performance.
2. Ensuring Scalable and Reliable Order Processing: As the source of truth for user orders, Horizon’s Full Stack engineers are responsible for integrating frontend and backend systems to guarantee order integrity, execute autopilot processes, manage skips, and validate delivery eligibility. They work on critical functionalities that ensure stability and accuracy across the platform.

By combining expertise in frontend development, backend infrastructure, and system integrations, the Horizon Full Stack Team plays a crucial role in delivering a seamless and reliable experience for users while ensuring operational excellence across CookUnity.

The Role:

As a Senior QA Engineer, you will play a key role in shaping the quality of our user experience by combining manual and automated testing strategies. You will be actively involved from the early stages of our most important initiatives, working closely with both Product and Engineering teams to gain context, define testing strategies, and ensure quality is built into every step of the process.

Your contributions will go beyond bug detection—you'll help clarify the scope of changes, determine what needs to be tested, and support developers and product managers in building reliable and delightful user experiences. By participating early in the definition phase, you’ll help prevent issues before they happen and promote a quality-first mindset across the team.

This role is a great opportunity to have a meaningful impact on how we build and deliver value to our users while ensuring we consistently deliver high-quality products.

Responsibilities:

• Develop, maintain, and improve test automation frameworks for web and mobile platforms.
• Leverage AI-driven automation tools to increase test coverage and efficiency.
• Collaborate with Engineering, DevOps, and Product teams to identify gaps in test coverage and define clear quality metrics.
• Collaborate closely with the Product team to gain early visibility into the most critical initiatives, contributing proactively to the definition and refinement of user stories.
• Design, maintain, and execute manual test cases for both regression and exploratory testing scenarios.
• Create and update comprehensive test plans and test documentation, ensuring alignment with functional requirements.
• Identify, document, and report defects and issues clearly and accurately using Jira, following up on their resolution.
• Perform root cause analysis on production issues and collaborate with Engineering to implement preventive solutions.
• Define and monitor key quality indicators (e.g., test coverage, flakiness rate, defect leakage) to drive continuous, data-informed improvements.

Minimum Requirements:

• Strong technical foundation in software testing and quality assurance, with a proven track record of ensuring high product standards through both manual and automated testing.
• Hands-on experience designing, executing, and maintaining manual test plans and test cases, including exploratory and regression testing.
• Proficiency in test automation tools for web and mobile, such as Playwright, Cypress, Selenium, and Appium (or similar).
• Proficiency in contract testing and API testing frameworks, such as Postman, RestAssured (or similar).
• Ability to write and debug automated tests in JavaScript, TypeScript, Kotlin, or similar languages.
• Strong understanding of software development lifecycle (SDLC), agile methodologies, and QA processes.
• Experience in setting up observability and reporting mechanisms for test execution and coverage.
• Excellent communication skills, with the ability to explain and summarize complex technical concepts to both technical and non-technical stakeholders.
• Comfortable working in a fast-paced startup environment, adapting to changing priorities and driving impact.

Preferred Requirements:

• Experience leveraging AI-driven testing tools for test case generation, automated debugging, and root cause analysis.
• Experience in B2C, e-commerce, or marketplace platforms.
