- Write clean, maintainable, testable, and production-grade code.
- Establish engineering standards, code review practices, and backend best practices.

Performance & Scalability

- Lead initiatives for system scalability, reliability, and performance optimization.
- Identify and eliminate bottlenecks in APIs, databases, caching layers, and infrastructure.
- Optimize application latency, throughput, and resource utilization.
- Design systems for horizontal scaling and fault tolerance.
- Implement caching strategies using Redis and distributed caching mechanisms.

Cloud & Infrastructure

- Build and manage containerized applications using Docker.
- Deploy, operate, and optimize workloads on Kubernetes clusters.
- Design CI/CD pipelines and automated deployment workflows.
- Implement infrastructure observability using monitoring, logging, and tracing tools.
- Drive cloud cost optimization and infrastructure efficiency initiatives.

AI Platform Development

- Develop backend services supporting AI/ML applications and LLM-based products.
- Build APIs for AI model inference, orchestration, and integration.




- Work with vector databases, embeddings, RAG architectures, and model-serving pipelines.
- Optimize AI workloads for performance, scalability, and cost.
- Collaborate with AI engineers and data scientists to productionize machine learning systems.

Reliability & Security

- Design resilient systems with high availability and disaster recovery considerations.
- Implement authentication, authorization, and API security best practices.
- Ensure compliance with security standards and data protection requirements.
- Conduct architecture reviews and proactively address technical debt.

Required Qualifications

- 6+ years of backend development experience.
- 4+ years of hands-on experience with Python.
- 2+ years of production experience with Go (Golang).
- Strong expertise in FastAPI and contemporary API design principles.
- Proven experience scaling applications from startup scale to high-traffic production environments.
- Extensive experience with Docker and Kubernetes in production.
- Strong understanding of distributed systems, microservices architecture, and event-driven systems.
- Deep knowledge of database optimization and query performance tuning.
- Experience with PostgreSQL, MySQL, MongoDB, Redis, or similar technologies.
- Strong understanding of concurrency, parallel processing, and asynchronous programming.
- Strong debugging, profiling, and performance optimization skills.

Preferred Qualifications

- Experience building AI-powered products or Generative AI applications.
- Hands-on experience with:
- LLM integrations (OpenAI, Anthropic, Gemini, etc.)
- RAG architectures
- Vector databases (Pinecone, Weaviate, Qdrant, Milvus)
- AI orchestration frameworks (LangChain, LlamaIndex)
- Experience with message queues such as Kafka, RabbitMQ, or NATS.
- Experience with cloud platforms (AWS, GCP, Azure).
- Knowledge of Infrastructure as Code (Terraform, Pulumi).
- Experience with service mesh technologies and Kubernetes operators.
- Exposure to MLOps and AI deployment workflows.
