Backend Developer (Go + React)

Location: Bangalore, Karnataka, India (Hybrid) Experience: 3 - 4 Years Job Type: Full-time What You'll Build At GreedyGame, you'll work on products that process large volumes of advertising, analytics, and monetization data powering the mobile ad ecosystem. This is a backend-heavy role. We're looking for engineers who are primarily strong backend builders with deep, hands-on Golang experience, and who can also confidently build and maintain React-based user interfaces when needed. The majority of your time will be spent on system design, API development, and backend architecture — not UI work. You will own features end-to-end—from database design and API development to frontend implementation and production deployment — with backend ownership as the core of

. Must-Have Skills Golang (Non-Negotiable, Primary Focus) • Minimum 1.5+ years of hands-on production experience building backend services in Golang. • Strong understanding of goroutines, channels, concurrency patterns, and memory management. • Experience building REST APIs, background workers, event-driven systems, or microservices. • Ability to design scalable backend architecture, debug production issues, optimize performance bottlenecks, and write maintainable Go code. • Comfortable owning backend systems independently, including infrastructure and deployment concerns. React & Frontend Development (Required, Secondary) • Experience building production-grade applications using React.js — this is a must-have, even though

is backend-focused. • Strong understanding of component lifecycle, state management, rendering behavior, and API integration. • Experience working with Next.js is preferred. • Familiarity with Redux, Zustand, or similar state management solutions. Databases & Infrastructure • Experience designing and optimizing SQL databases such as PostgreSQL or MySQL. • Strong understanding of query optimization, indexing, transactions, and schema design. • Experience working with Redis for caching. • Familiarity with Docker, Kubernetes, CI/CD pipelines, and cloud environments is highly preferred. What Will Make You Stand Out • Experience working on ad-tech, analytics, fintech, gaming, SaaS, or other high-scale platforms. • Experience handling systems serving millions of API requests or large-scale datasets. • Strong understanding of observability, logging, profiling, and production debugging. • Contributions to open-source projects, technical blogs, or side projects built using Go. We May Not Be the Right Fit If • Most of your experience is frontend-focused with limited backend ownership. • You have only academic, training, or side-project exposure to Golang. • You have not worked with Golang in a production environment. • You have no working experience with React, even if your focus is primarily backend. • You prefer narrowly defined tasks over end-to-end product ownership. What Success Looks Like Within your first few months, you will: • Build and optimize scalable Golang backend services as your primary responsibility. • Ship production-ready features across the backend and, when needed, the frontend. • Improve system performance and reliability. • Contribute to architectural discussions and code reviews. • Take ownership of features from design through deployment.
