**Product QA role · iOS-first · AI-native product**
BRAYN is building a new category of growth platforms: mobile-first, gamified, AI-powered. Inside BRAYN, learning feels like gameplay, progress becomes measurable proof, and AI mentors guide users through real decisions and career development. We ship fast, iterate constantly, and experiment across multiple product layers — from mobile UX and AI coaching to experimentation frameworks and new product mechanics.
We’re looking for a product-minded QA Engineer who wants to help the team ship faster with confidence. This role is not about running checklists. It’s about owning quality across mobile, API, AI features, and release cycles.
**What you’ll work on**
**Mobile product quality (iOS-first)**
* Functional testing of the iOS app across features and releases
* Regression testing for product changes and new feature launches
* Testing across different devices, OS versions, and network conditions
* Validation of UI logic, animations, reward systems, and interaction flows
BRAYN is a UX-sensitive product, so attention to experience quality matters.
**API & system behaviour**
You’ll validate product logic beyond the UI layer. This includes:
* API request/response validation
* Auth/session flows
* Caching behaviour
* Retries and idempotency
* Integration edge cases
* Failure scenarios
**AI-powered features**
BRAYN includes AI mentors and AI-driven product features. Testing these systems requires thinking differently from traditional deterministic testing. You will work with:
* Non-deterministic outputs
* Fallback logic
* Timeouts and degraded states
* Prompt variations
* Output boundaries and safety behaviour
You should think in behavior patterns, not exact expected strings.
**Release confidence**
You will help the team ship fast without losing control over quality. This includes:
* Pre-release validation
* TestFlight checks
* Crash signal review
* Release risk assessment
* Production sanity checks
QA helps the team move faster safely.
**Product signals & analytics**
Quality in modern products includes validating signals. You may validate:
* Analytics events
* Product funnels
* Feature triggers
* Unlock mechanics
* Experiment conditions
**Feature flags & experimentation**
BRAYN actively experiments. You’ll test:
* Feature flags
* Staged rollouts
* Experiment logic
* Fallback behavior
**Admin panel & CMS**
BRAYN includes operational tools used by the team. You will test:
* Content flows
* Configuration logic
* Admin features
**Quality systems**
Beyond testing features, you’ll help improve how the team works with quality. Examples:
* Test checklists
* Reusable QA scenarios
* Release validation routines
* QA documentation
**What the role looks like in practice**
Approximately:
**80–90%**
* Manual product testing
* API testing
* Release validation
* Edge-case discovery
**10–20%**
* Automation-related work
* AI-assisted QA workflows
* Test scenario design
* Collaboration with the whole product team
You don’t need to be an automation engineer, but you should think about scalable quality patterns.
**Tools you’ll likely work with**
* iOS builds / TestFlight
* Postman
* Charles / network debugging tools
* Sentry or crash monitoring tools
* Notion / task documentation
* AI tools (ChatGPT, Claude, etc.)
**AI awareness**
BRAYN is an AI-native product. We expect QA engineers to work comfortably with modern AI workflows. You should be able to:
* Understand how LLM-based systems behave
* Test behaviour under uncertainty
* Explore edge cases with AI assistance
* Generate scenarios and analyze failures with AI tools
AI should make your QA work faster and deeper.
**Nice to have**
* Experience testing mobile subscriptions or purchase flows
* Familiarity with feature flags / experimentation systems
* Exposure to analytics validation
* Basic performance awareness (latency, degraded UX)
* Some exposure to test automation or scripting
**Languages**
Strong written and spoken communication in:
**English** — used for documentation and product collaboration
**Russian** — used in internal team communication
**What we value**
* Product intuition
* Curiosity and ownership
* Clean communication
* Comfort with ambiguity
* Thinking about quality as a system, not a checklist
**What success looks like in this role**
Within the first months you should help the team:
* Detect risks earlier in development
* Improve release confidence
* Reduce production issues
* Increase speed without sacrificing quality
