Senior Full-Stack QA Engineer
About the position
At MEDvidi, we are transforming mental healthcare by making it more accessible and affordable across the United States. Our mission is to remove barriers to mental health support and ensure that everyone can access the care they need. We are building an AI Ops&Growth Team - a fast-moving, startup-style team focused on automating operational processes and maximizing revenue impact. This small team works at high speed, ships in days, and values experimentation. We are looking for a Senior Full-stack QA Engineer who thrives in this environment: someone who is flexible, fast, and genuinely excited about building things with the help of AI. You will be a quality partner in a cross-functional Growth Team working on automating MedOps workflows (slot management, supply/demand balancing, traffic redistribution) and, once those are in place, moving on to top-of-funnel growth experiments.This is not a typical QA role where you only check releases before they go live.
Responsibilities
• Own product quality end-to-end across frontend, backend, APIs, databases, and LLM-based features
• Balance manual, automated, and exploratory testing approaches
• Lead E2E and API testing to ensure reliability of complex workflows
• Validate data correctness and system behavior using SQL (PostgreSQL)
• Participate in product discovery and delivery: influence requirements, acceptance criteria, and release decisions
• Identify quality risks early, drive preventive actions, and improve system testability
• Collaborate with engineering and AI teams to ensure reliable and predictable system behavior
• Contribute to test infrastructure, documentation, and team knowledge sharing
Requirements
• 5+ years of commercial experience as a Full-Stack QA Engineer in primarily product companies (not agency or outsourcing)
• Strong JavaScript knowledge and understanding of modern full-stack systems end-to-end
• Experience with JS-based/TS-based test automation frameworks
• Hands-on experience combining manual and automated testing in fast-release environments
• Proven experience building and evolving QA approaches and quality frameworks
• Deep understanding of client–server architecture, data flows, system boundaries, and failure modes
• Strong knowledge of testing principles, techniques, and test design methodologies
• Solid experience with E2E and API testing
• Advanced SQL skills and experience with PostgreSQL (data validation, complex queries, integrity checks)
• Experience working with quality metrics, test coverage models, and practical QA KPIs
• Product-oriented mindset: ability to balance quality, speed, and business goals
• Fluent Russian; English level B2 or higher
• Ability to work CET-overlapping hours, with location outside Belarus and Russia
Nice-to-haves
• Experience testing AI/LLM systems, including hallucinations, response quality, prompt stability, and evaluation approaches (evals, guardrails).
• Experience building QA processes from scratch or scaling them in growing startups
• Understanding of CI/CD quality gates, observability, and production quality monitoring
Benefits
• Health insurance after probation period
• Sports & wellness compensation
• Fully remote, long-term B2B collaboration
• 19 working days of vacation per year
• 4 additional wellness days per year
• Paid sick leave for the first 5 working days
• Gifts to employees for important events
• Career Development
• Personalized English lessons via Preply
