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
Your Engineering Stack

The Interview Loop · Screening for the Top 1%
Rounds
Round I · Recruiter Screen Evaluation of backend experience, problem-solving approach, and project depth
Round II · Hiring Manager Deep dive into backend projects, APIs, databases, and system design thinking
Round III · Domain Lead Live coding + backend problem-solving + discussion on scalability and distributed systems
Final · Leadership Culture fit, ownership mindset, and ability to operate in a high-velocity startup environment

Your Growth Trajectory TestMu AI is a high-growth environment where we promote based on complexity solved, not years of tenure. As a Backend Developer, you have a massive runway to scale from an Individual Contributor (IC) into a core Engineering Leadership role, working alongside pioneers in agentic intelligence.
