Product Engineer (TypeScript/React)

The company considers specialists residing in Cyprus or EU countries.

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’re looking for a Product Engineer (TypeScript/React) to join our Digital Product teams across both Web and Mobile. The mission is to deliver the best possible customer experience in users account management.

We expect you to

• Drive continuous trading UX improvements for traders: direct feedback, usability research, refinement of workflows and critical-moment behaviour.
• Build hybrid trading UI in React for web: integrate third-party terminal and deliver first-party widgets around it, including session, entitlements, theming, and deep links.
• Deliver customer facing clarity in communications, statuses, errors, notifications, market alerts.
• Co-design backend contracts for trading UX: event models, pending/recovery states, partial failures, out-of-order/late updates, state consistency with the backend.
• Improve frontend performance and reliability: profiling under real market load, telemetry/observability, safe releases, incident response, regression prevention.

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 create new in the state of uncertainty, understand big complex systems, navigating root causes, and choose mindful solutions.
• Proven experience with retail-facing trading-terminal: you built or operated broker/exchange UIs and understand trader workflows and failure modes (orders, positions, market data, execution states).

Strong React experience building complex modular UIs with state management. Experience in tuning UI across browsers and devices: consistency, profiling, performance optimizations (rendering/memory/network/protocols).

• Experience in real-time UI under race conditions: heavy streaming, out-of-order updates, reconnect/replay, stale data, UI-vs-server reconciliation.
• Frontend security experience in finance: sessions, tokens, WAF, XSS, PII handling.
• Fluent English: daily communication in international teams, technical discussions, documentation.

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, teamleads 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.
• Comfortable conditions: competitive salary, medical compensation, fully remote working options.
