Backend Developer (Go + React)

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 the role.

• 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 the role 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.
