About the Position
Mobile QA Engineer
Change is a rapidly growing FinTech providing everyone in Europe access to exciting investments. Tens of thousands of people from 30 EU countries trust Change to build their financial future.
We believe the world would be a fundamentally better place if everybody invested. Since 2010, we’ve been on a mission to enable wealth creation by making investing simple, affordable and accessible.
Our users trade cryptocurrencies, alongside CFDs on stocks, indices, currencies, gold, oil, and other financial instruments - all in one place, on mobile, with the regulatory protections of a Dutch investment firm.
We are hiring a Mobile QA Engineer to own quality for our Flutter app across iOS and Android, and to treat AI agents and tooling as a core part of how modern QA gets done.
Responsibilities
- Own quality for the mobile app. Manual and automated testing across iOS and Android, from onboarding and KYC to funding, trading and custody flows.
- Build and grow our mobile test automation. Design and maintain an automated suite (integration_test, Appium, Maestro or similar) that gives the team confidence to ship fast without breaking money-moving flows.
- Test the flows that matter most. Order tickets, charts, portfolio, deposits and withdrawals - with a sharp eye for edge cases, error states and the things that only break under real market conditions.
- Own release quality. Regression passes, device/OS coverage, staged rollouts, crash triage and being the last line of defence before an update reaches 120,000 users.
- Make quality measurable. Clear test plans, bug reports engineers can act on, and metrics that show where quality is improving and where it is not.
- Use AI agents to scale QA. Generate test cases, triage crash logs and expand coverage with agentic tooling - while keeping human judgement where it counts in a regulated product.
Requirements
- QA depth
- 3+ years in QA, with real experience testing mobile apps on both iOS and Android.
- Hands-on test automation experience - Flutter integration_test, Appium, Maestro, or equivalent mobile automation frameworks.
- Strong test design instincts: you think in edge cases, boundary conditions, error states and "what happens if things go wrong".
- Comfortable reading API responses, inspecting logs, and writing clear, reproducible bug reports that engineers respect.
- Understanding of CI/CD and how automated tests fit into a fast, frequent release cadence.
- AI-native, agentic-first
- You use AI tools and coding agents (ChatGPT, Claude, Gemini, Cursor or similar) regularly as part of your QA workflow.
- You have built or customised at least one practical AI-assisted testing or automation workflow.
- You have clear judgement on where humans must stay in the loop in a regulated, money-moving product. You are not impressed by demos.
- You understand that strong AI outputs depend on good context, structure and human judgement.
- Mindset
- You communicate in writing well enough that meetings shrink - crisp test plans, clear bug reports, honest release notes.
- You enjoy the boring craft of quality: the regression pass, the flaky-test hunt, the edge case nobody else thought of. You do not consider this work beneath you.
- You are visibly comfortable saying "I don't know" and "I was wrong". You change your mind when the evidence changes.
- You want to grow your scope and impact here over time. We will invest in that growth as the team scales.
Nice to Have
- Experience in fintech, trading, payments or another trust-critical consumer product.
- Familiarity with MiFID II, MiCA, PSD2 or similarly regulated environments.
- Experience testing trading surfaces - order tickets, charts, watchlists, order books and portfolio screens.
- Performance, security or accessibility testing experience.
- Greek or Dutch language is welcome but not required - we work in English.
We Offer
- Hybrid role (Athens)
- Travel to Amsterdam and Estonia a few times a year
- Competitive base salary (40,000 - 65,000/year)
- Perks and benefits
- Learning budget to keep you sharp
- Real ownership and influence
- Fast decisions, zero politics
- A real shot at growing with the company long-term
