🚀 About the Role

We’re looking for a Senior QA Engineer to own and elevate end-to-end quality for a crypto-enabled product operating in a regulated fintech environment.

This is a hands-on, senior-level role with a strong focus on automation, crypto transaction lifecycles, and modern testing practices, including AI-assisted testing. You’ll work closely with engineering, product, and compliance teams to ensure high-confidence releases, strong observability, and prevention-focused quality practices.

If you care about how systems fail, not just how they work — this role is for you.

🎯 What You’ll Be Responsible For:

• Embedding “shift-left” quality practices into the engineering team (acceptance criteria, test strategy, testability & observability)
• Owning end-to-end testing of crypto transaction flows across UI, API, and backend services
• Validating full crypto lifecycles, including:
  • Signing → broadcast → mempool
  • Confirmations / finality
  • Settlement, reconciliation, retries, idempotency
• Designing, maintaining, and scaling TypeScript-based E2E automation (e.g. Playwright-level frameworks)
• Ensuring stable and meaningful CI/CD execution (gating, reporting, flaky test control, parallelisation)
• Strong API testing (authN/authZ, limits, validation rules, negative cases, error handling)
• Testing non-functional requirements critical for regulated crypto products:
  • Resilience & failure handling
  • Performance
  • Monitoring & alerting behaviour
  • Auditability & production readiness
• Partnering with Engineering, Product, Compliance/Risk, and Operations on:
  • Release readiness
  • Traceable test evidence
  • Clear go / no-go decisions
• Contributing to test tooling and diagnostics, including reading/debugging services or helpers in Python and/or Go
• Applying AI-assisted testing pragmatically:
  • Test idea generation
  • Exploratory testing support
  • Log and failure triage
  • While actively managing risks (hallucinations, data leakage, over-reliance)
• Driving continuous improvement via root cause analysis, defect trends, and prevention (not just detection)

✅ What We’re Looking For:

• 5+ years of experience in QA / test automation with senior-level ownership of quality outcomes
• Hands-on experience testing crypto or digital asset products in production, or equivalent depth in regulated fintech with crypto rails
• Deep understanding of crypto transaction systems and where they break:
  • Transaction lifecycle realities
  • Address and custody risk
  • Key management controls
  • Third-party / node / provider risk
  • Regulatory and compliance expectations
• Strong experience with TypeScript E2E automation and code quality enforcement (linters, reviews, CI stability)
• Ability to read, debug, and contribute to tooling or services written in Python and/or Go
• Excellent API testing skills (REST/JSON, event-driven where applicable, contract/schema validation)
• Experience integrating automation into CI/CD pipelines (GitHub Actions, Jenkins, or equivalent)
• Familiarity with cloud environments (AWS or similar) and test environment realities
• Practical, thoughtful use of AI in testing to improve speed and coverage
• Strong analytical mindset, clear written communication, and confidence working cross-functionally
• Experience in regulated fintech with crypto exposure is required

📍 Location:

Belgrade (remote and hybrid)
Warsaw, Kraków (remote)
Eastern Europe (remote)

💷 Compensation:

Up to £60,000 per year

🌍 What Matters:

• You think in systems and failure modes, not just test cases
• You value automation, signal quality, and prevention over manual regression
• You’re comfortable operating in regulated, high-stakes environments
• You want real ownership over quality — not a checkbox role
