- Implement microservices with reliability, observability, and maintainability.
- Optimize backend systems for performance, cost, and scalability in cloud environments.
- Work with data scientists to productionize ML/GenAI models (deployment, monitoring, lifecycle).
- Integrate LLMs, vector databases, embeddings, and RAG pipelines into services.
- Develop APIs and SDKs to expose AI/ML capabilities.
- Apply responsible AI practices: bias detection, security, compliance.
- Translate business needs into technical designs with architects and product teams.
- Mentor junior engineers, enforce best practices, and support CI/CD automation.

Key Skills
- 6+ years of backend engineering experience with Python in enterprise or product environments.
- Strong expertise in FastAPI, Flask, Django, or similar frameworks.
- Proven experience working on AI/ML/GenAI projects (model deployment, serving, integration).
- Hands-on with data processing frameworks (Pandas, PySpark, Dask) and ML frameworks (PyTorch, TensorFlow, Hugging Face).
- Familiarity with vector databases (Pinecone, Weaviate, FAISS, Milvus) and orchestration tools (Airflow, Dagster, Prefect).
- Strong understanding of REST/gRPC APIs, microservices, containerization (Docker, Kubernetes), and CI/CD pipelines.
- Cloud experience with AWS, Azure, or GCP (serverless, Kubernetes, AI/ML services).
- Solid understanding of security, scalability, and performance tuning in backend systems.
Preferred Qualifications
- Experience with LLMOps/ MLOps (MLflow, Weights & Biases, LangChain/LangGraph).
- Exposure to multi-agent systems, advanced RAG, or AI governance patterns.
- Prior experience in data-intensive applications (streaming, big data pipelines).
- Open-source contributions or publications in AI/ML/GenAI.
