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
