Role overview
ENJOY Gaming is a software provider focused on creating high-quality digital entertainment experiences, including Slots and Live Games, with a team of experienced professionals in game development, product, and design driven by innovation and quality. They value ownership, excellence, and drive as core principles. They are looking for a Lead Full-Stack Engineer with a passion for creative game design and systems engineering. This is not a backlog ticket-pulling role — the successful candidate will be the technical authority for their products, leading two completely different engineering ecosystems: the highly optimized, memory-sensitive world of game clients and the backend infrastructure. The role bridges the gap between creative vision and technical reality, ensuring that the incredible player experience is powered by a robust, secure, and scalable backend.
Responsibilities
- Design, implement, and maintain complete game features; seamlessly integrate scalable server-side backend services with high-performance client-side gameplay and UI logic (E2E Game Architecture)
- Design a flexible, modular backend that efficiently serves data to various frontend game clients, ensuring seamless integration regardless of the client engine used (Decoupled Systems)
- 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 (Full-Stack Optimization)
- Implement robust real-time data collection, logging, and crash reporting to track the user journey from client-side actions to back-end server responses (Unified Observability)
- Monitor the entire stack to swiftly detect, diagnose, and resolve cross-domain issues — whether they originate as client-side crashes or backend server bottlenecks (System Health & Proactive QA)
- 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 (Security & Risk Mitigation)
- Serve as the core bridge connecting UI/UX designers, Game Designers, and engineering leadership, translating creative requirements into actionable code while ensuring the backend can support those designs (Act as the Technical Translator)
- Mentor developers in modern client-side and backend techniques, fostering a culture of high-quality code and technical ownership (Elevate the Team)
- Create and maintain a unified knowledge base covering both sides of the stack — from API specs and server infrastructure to engine integration manuals (Set the Standard for Documentation)
- Holistically scope features during sprints, ensuring technical requirements align with business goals while actively managing and reducing technical debt (Drive Agile alignment)
- Organize planning and prioritization so 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 (Strong Planning and prioritization)
- Work with product owners and game designers to translate their vision into technical reality, reviewing mechanics and proposing viable, performant alternatives (Stakeholder management)
- Marshal monitoring telemetry to ensure servers stay up during massive traffic spikes and adjust the approach to facilitate high availability (Architecture engineering)
- Balance the demands of shipping features fast against the necessity of keeping the codebase clean, scalable, and modular (Product engineering)
Requirements
- 6+ years of development experience
- 1+ year of leadership experience
- Proven Full-Stack Expertise: Deep professional experience in both game client development and scalable server-side backend architectures
- High Tolerance for Complexity: comfortable diving into ambiguous problems and designing systems from the ground up
- Proactive Problem Solver: find and fix memory leaks, architecture flaws, or security vulnerabilities before they impact a player
- Exceptional Communicator: can explain complex backend constraints to non-technical stakeholders and break down creative requirements into clear engineering tasks
- Experienced Leader: track record of mentoring engineers, driving architectural decisions, and leading projects through the full software development lifecycle
Nice to have
- iGaming/Gambling experience will be a huge plus
- Experience with Python
