Full description
Role Summary
Genius is building a professional, high-velocity on-chain trading terminal where correctness, determinism, and execution integrity are non-negotiable. This role owns automated testing across both the frontend interface and the on-chain execution layer.
The Senior QA Engineer is responsible for designing, implementing, and maintaining automated test coverage that continuously validates UI behavior, backend coordination, and on-chain state transitions.
This is an automation-first role with real ownership over quality infrastructure.
Core Responsibilities
- Design and maintain automated test suites covering:
- Frontend user flows (wallet connection, balances, trading, error states)
- Backend coordination and API contracts
- On-chain execution flows and state transitions
- Build deterministic tests for:
- Order submission and cancellation
- Slippage enforcement and fee calculation
- Transaction lifecycle (submitted, pending, confirmed, reverted)
- Balance and position reconciliation between UI and chain
- Automate regression coverage for critical trading paths
- Validate frontend state against on-chain truth
- Create mocks, fixtures, and local chain environments where appropriate
- Integrate automated tests into CI/CD pipelines
- Triage failures and distinguish product bugs from test instability
- Work closely with engineers to enforce testability at the architecture level
Required Qualifications
