Senior QA Engineer

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

• 5+ years experience in QA engineering with a strong automation focus

• Proven experience testing complex, stateful systems

• Strong proficiency with modern test frameworks for:

  • Frontend automation (e.g. Playwright, Cypress, Selenium)
  • API and integration testing

• Ability to design deterministic, non-flaky tests

• Strong debugging skills across frontend, backend, and execution layers

• Clear written communication and disciplined documentation

Preferred Qualifications

• Experience testing trading systems, financial platforms, or real-time systems

• Familiarity with blockchain execution models and on-chain state

• Working knowledge (or fast ramp-up ability) on concepts such as:

  • Wallets and signing flows
  • Gas estimation and failures
  • Slippage, MEV, and partial execution scenarios

• Experience running tests against:

  • Local chains or forks
  • Testnets and simulated mainnet conditions

Explicitly Not Part of This Role

• Manual-only testing without automation ownership
• Writing superficial UI tests that do not validate execution correctness
• Treating QA as a downstream or passive function

Success Criteria

• High-confidence releases backed by automated coverage
• Early detection of execution-breaking regressions
• Low test flakiness and fast CI signal
• Clear ownership of quality across frontend and on-chain execution
