QA Engineer (Manual, Web Platform)

StellarTech is an international, fast-growing product IT company that builds and publishes subscription-based mobile apps in EdTech. Our Platform team builds the company's own platform: web funnels, payments, subscriptions and integrations with third-party services. It's the core that all our products run on. We're looking for a QA Engineer to join a team of manual QA engineers. You'll own the quality of Platform functionality in a startup rhythm with short iterations and frequent releases. QA is also where other teams (Monetization, Finance, Product Tech) come first when something looks wrong. So we need a mature specialist who finds the root cause, communicates clearly and helps improve how we work, not someone who only runs test cases. What you'll do Test new features end to end during development: frontend, backend, APIs and third-party integrations Run regression testing before releases and smoke testing on production after each release Validate business and technical requirements with Product and Engineering before development starts Investigate defects with logs, API responses and network traffic, and write clear, reproducible bug reports Be the first line for requests from Monetization, Finance and Product Tech: reproduce the issue, assess severity and escalate with facts Maintain test documentation in TestRail, Jira and Confluence Work with the Automation QA team to decide which cases to automate Must-have 4+ years of manual QA of web applications (frontend, backend, API) Risk-based test design: you can explain what you test, what you don't, and why API testing with Postman / Charles and Swagger / OpenAPI Root cause investigation with Chrome DevTools (HAR, network, storage) and logs Hands-on with the full release cycle: feature, regression and production smoke testing You use AI tools (Claude, Cursor or similar) in your daily QA work and critically check what they produce Experience in a product company or startup with frequent releases Written English good enough for documentation and bug reports Ownership and transparent communication: you flag risks and delays early Nice to have Payments and subscriptions testing (Chargebee, Adapty, Payrails, trials, taxes, Apple Pay / Google Pay) Web funnels and A/B experiments Analytics event validation (Google Analytics, Meta Pixel, GTM dataLayer) Datadog / Grafana Testing AI-powered features Basic Playwright / TypeScript Why join us You'll work on a platform that decides how fast a subscription business can grow AI-first company: AI is being built into the company's work centrally, well beyond generating test cases No micromanagement, high engineering standards, fully remote Hiring process: Recruiter screening → Technical interview with the Hiring Manager and a QA engineer →Final interview. We move fast: the whole process can take about 1 to 2 weeks. Interested or know someone who fits? Apply or send us a message. Originally posted on Himalayas
