Data-Driven Lab

is an international IT company developing products for fintech, edtech, and analytics industries. Alongside product development, we help businesses grow with a full range of digital marketing services. We are looking for a Product Engineer (QA) to join the team accountable for the Trading Experience across both Web and Mobile. The mission is to deliver the best possible trading conditions while keeping risk and abuse at controlled levels.

We offer

• Direct feedback loop with customers: you will see how you impact their experience and their success.
• True peer-peer relationships within teams with no managers, team leads, or any other roles defined for them - everything is managed by you and your teammates through collaboration based on agreements, not titles.
• Non-fading startup pace: autonomous decision making inside the team, and the ability to choose the way the product evolves.
• Engineering-driven environment: we value engineering experience and creative thinking combined, so you’ll be able to handle the process end-to-end.
• No gatekeepers: as our teams are completely autonomous, the development, security, and sustainability are owned by you.

We expect you to

• Own end-to-end quality of trading scenarios: market data delivery, order placement and execution, position management, trading parameter calculations etc.
• Test across the full stack: web and mobile trading terminals, APIs, and backend flows with functional, integration, and regression tests under both normal and stressed market conditions.
• Drive test automation: design, build, and maintain automated test suites covering core trading logic, market-making, pricing, execution. Embed automated checks into CI/CD pipelines.
• Validate trading business logic: verify correctness of execution rules, margin calculations, order lifecycle, pricing formation, and risk parameter behaviour.
• Manage test data and environments: own test data strategies, environment configurations, and market condition simulation.

What is important to us

• You consistently put customer value and team goals above everything else when making any decision during your work.
• Engineering mindset: ability to reason about complex real-time systems, understand market dynamics, investigate root causes of trading anomalies, and design robust solutions.
• 5+ years in QA engineering with ownership of quality across the full delivery cycle in a real-time product (race conditions, out-of-order updates, state consistency).
• 3+ years maintaining automated test frameworks; experience integrating quality checks into CI/CD pipelines.
• Understanding of trading mechanics: order lifecycle, execution models, margin and pricing formation.
• Awareness of compliance-sensitive flows and data handling requirements.
