Backend Developer
📍 Noida | 🕐 Full-Time | 🧭 Experience: 2–3 Years
The Mission
We aren't building traditional backend systems — we're powering the infrastructure behind Agentic Intelligence. TestMu AI is building the world's first AI-native platform where backend systems don't just serve requests, they enable autonomous decision-making, execution, and scale.
The name "TestMu" comes from our community conference. Our users and team aren't an audience — they're the heartbeat of what we build. We believe AI augments human potential. It doesn't replace it.
You'll be building the core backend systems that power AI-driven workflows — ensuring high performance, scalability, and reliability at every layer.
The Pillars of Impact
🚀 1. Core Backend & System Architecture (50%)
- Build and scale high-performance backend services and APIs
- Design efficient database schemas, query optimization, and data flows
- Write clean, logical, production-grade code (Python, Golang, or similar)
- Own system performance — latency, throughput, and reliability
⚙️ 2. Backend for AI Systems (30%)
- Develop backend systems supporting AI agents and autonomous workflows
- Handle large-scale data processing, async tasks, and event-driven systems
- Integrate backend infrastructure seamlessly with AI/ML components
🧠 3. Scalability & Distributed Systems (20%)
- Contribute to microservices architecture and service decomposition
- Build fault-tolerant, highly available distributed systems
- Optimize systems for high concurrency and real-time execution
