• Build microservices for resource orchestration, telemetry ingestion, capacity and asset management.
• Design REST/gRPC APIs and event-driven systems.
• Drive performance optimization, scalability, and reliability best practices.
• Embed SRE principles, observability, and security-by-design.
• Mentor senior engineers and influence technical roadmap decisions.

Required Skills

• Strong hands-on experience in Java and/or Python.
• Deep understanding of distributed systems and microservices.
• Experience with Kubernetes, Docker, CI/CD, and cloud-native deployments.
• Databases: PostgreSQL/MySQL, NoSQL, time-series data.
• Messaging systems: Kafka / Pulsar / RabbitMQ.
• Observability tools: Prometheus, Grafana, ELK/OpenSearch.
• Secure backend design (OAuth2, RBAC, audit logging).

Nice to Have

• Experience with DCIM, NMS, or infrastructure automation platforms.
• Exposure to hyperscale or colocation data centers.
• AI/ML-based monitoring or capacity planning experience.

Why Join

• Architect mission-critical platforms for large-scale data centers.
• High-impact principal role with deep technical ownership.
• Work on complex, real-world distributed systems problems.

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
