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 looking for a Senior Full-Stack QA Engineer to join one of our cross-functional product teams. Our engineering teams work on automating clinical and operational workflows, building AI-powered features, and integrating third-party services - all with a direct impact on the quality of care our medical providers deliver.

You will be an embedded quality partner in a cross-functional team of backend and frontend engineers, a data analyst, and a PM. This is not a gatekeeper role — you will be involved from discovery and requirement shaping through to delivery and ongoing support.

Requirements

• 5+ years of commercial experience as a Full-Stack QA Engineer, primarily in product companies (not agency or outsourcing)

• Strong JavaScript/TypeScript knowledge, solid understanding of modern full-stack systems end-to-end, and deep familiarity with client–server architecture, data flows, system boundaries, and failure modes

• Hands-on experience with JS/TS-based test automation frameworks (Cypress, Playwright) and proven ability to combine manual, automated, and exploratory testing in fast-release environments

• Strong knowledge of testing principles, techniques, and test design methodologies, with solid experience in E2E and API testing

• Experience building and evolving QA approaches, quality frameworks, and CI/CD quality gates with an eye on observability and production quality monitoring

• Advanced SQL skills

• Product-oriented mindset: ability to balance quality, speed, and business impact

• Fluent Russian; English level B2 or higher

• Ability to work CET-overlapping hours, with location outside Russia

Nice to Have

• Experience testing AI/LLM systems: response quality, prompt stability, hallucination detection, evaluation approaches (evals, guardrails)

• Experience building or scaling QA processes in a fast-growing product startup

Responsibilities

• Own product quality end-to-end across frontend, backend, APIs, databases, and LLM-based features

• Design, implement, and continuously evolve QA strategies, processes, and quality metrics

• 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 LLM behavior

• Contribute to test infrastructure, documentation, and team knowledge sharing

Why Join Us

• Work on a product used daily by patients and medical providers across the US - your quality work has a direct impact

• Shared ownership culture: every team member is responsible for quality

• Real autonomy: you define how quality is approached in your team, not just execute a predefined plan
