Job description

Company Name: Blacklight Studio Works

Job Role: Backend Developer

Work Type: Full-Time

Experience: 2-4 Years (with production system experience)

Qualification: Bachelor’s Degree in Computer Science or Related Field

Location: Noida, Remote / Hybrid (as applicable)

About the Role :

We build real-time multiplayer mobile games where milliseconds matter. As a Backend Developer on our team, you’ll own the systems that power live gameplay for thousands of concurrent players - matchmaking, game state sync, leaderboards, player progression, and the WebSocket infrastructure that ties it all together. You’ll ship to production frequently and have a direct impact on how our games actually feel to play.We’re language-agnostic and AI-native in how we build.

What You’ll Do :

• - Design and build backend services for live multiplayer features : matchmaking, real-time state sync, room/session management, leaderboards, and player progression
• - Build and maintain low-latency WebSocket services and REST APIs that thousands of mobile clients depend on
• - Optimize for the realities of mobile gameplay : spiky traffic, dropped connections, variable network quality, and concurrent player scale
• - Collaborate with game developers, product, and ops to ship features players actually feel
• - Write code that's debuggable in production - good logging, metrics, and tracing are table stakes here
• - Use AI coding tools as a daily multiplier - and own what you ship

What We’re Looking For :

• - More than 1 year of professional backend experience, with at least one production system you can talk about in depth
• - Strong with at least one of Go, Node.js/TypeScript, or Java/Spring Boot - and open to picking up the others
• - Solid grasp of REST API design, auth patterns, and HTTP fundamentals
• - Solid knowledge of relational and in-memory databases - SQL at minimum
• - Pragmatic with AI coding tools - you use them well and know when not to

Nice to Have :

• - Experience in gaming, real-time systems, fintech, ad-tech, or other latency-sensitive domains
• - Familiarity with message queues / streaming - GCP Pub/Sub, Kafka, NATS
• - Exposure to game-specific concerns : anti-cheat, server-authoritative state, tick-rate trade-offs, deterministic simulation
• - Open-source contributions or side projects we can look at

Why Join Us :

• - Ship features that thousands of players hit on day one - short feedback loop, real impact
• - Modern stack, modern tooling, and a team that treats AI-assisted development as a first‑class workflow
• - Small enough that your decisions matter, with backend peers to learn from
