Full description
We are looking for a Lead Fullstack Developer(Node.js, React) with a passion for creative game design and systems engineering. You won’t just be pulling tickets from a backlog: you’ll be the technical authority for our products. You will lead two completely different engineering ecosystems: the highly optimized, memory-sensitive world of game clients and the backend infrastructure. You will bridge the gap between creative vision and technical reality, ensuring that the incredible experience enjoyed by players is powered by a robust, secure and scalable backend.
What You Will Do:
E2E Game Architecture: Design, implement, and maintain complete game features. You will seamlessly integrate scalable server-side backend services with high-performance client-side gameplay and UI logic
Decoupled Systems: Design a flexible, modular backend that efficiently serves data to various frontend game clients, ensuring seamless integration regardless of the client engine used
Full-Stack Optimization: Balance performance across the entire product. Optimize server-side load management and database queries while simultaneously managing client-side memory and frame rate stability across a wide range of devices
Unified Observability: Implement robust real-time data collection, logging, and crash reporting, to track the user journey from client-side actions to back-end server responses
System Health & Proactive QA: Monitor the entire stack to swiftly detect, diagnose, and resolve cross-domain issues – whether they originate as client-side crashes or backend server bottlenecks
Security & Risk Mitigation: Implement E2E security protocols for secure client-server communication. Protect sensitive user data on the server while deploying client-side risk mitigation, such as anti-cheat mechanisms and exploit prevention
Act as the Technical Translator: Serve as the core bridge connecting UI/UX designers, Game Designers, and engineering leadership. You will help translate creative requirements into actionable code while ensuring the backend can support those designs
Elevate the Team: Mentor developers in modern client-side and backend techniques, fostering a culture of high-quality code and technical ownership
Set the Standard for Documentation: Create and maintain a unified knowledge base covering both sides of the stack – from API specs and server infrastructure to engine integration manuals
Drive Agile alignment: Holistically scope features during sprints, ensuring technical requirements align with business goals while actively managing and reducing technical debt
What to Expect:
Strong Planning and prioritization: You will organize the plan so that you and the team can seamlessly shift gears from optimizing a memory allocation issue in the morning to designing a stateless architecture handling thousands of concurrent players in the afternoon
