Job description

Company Name: TestMu AI

Job Role: Backend Developer

Experience Required: 2-3 Years

Employment Type: Full-Time

Location: Noida, India

Industry: Artificial Intelligence / Software Development

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 :

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

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

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 :

Tech/Tools :

• Python / Golang : Building core backend services and logic-heavy systems
• AWS / GCP : Deploying and scaling distributed backend infrastructure
• Kafka / RabbitMQ : Handling asynchronous processing and event-driven workflows

The Bar :

Signal :

• Core Backend Experience : 2- 3 years of hands-on experience building APIs, backend systems, and scalable services
• Problem-Solving : Ability Strong fundamentals in data structures, algorithms, and logical thinking
• System Design Understanding Ability to design scalable backend systems with clear architectural thinking
• Ownership & Execution : Experience owning backend features end-to-end in a fast-paced environment

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.

Perks of the Future :

• Health & Wellness : 100% premium covered insurance for you + family (spouse, kids, parents) with annual check-ups.
• Fuel for Innovation : Fresh, daily gourmet lunch and dinner served at our Noida HQ.
• Seamless Transit : Safe, GPS-enabled cab facilities for eligible shifts (home-office-home).
• POD Culture : Dedicated quarterly budgets for team-building, offsites, and collaborative celebrations.
