AI/ML Enablement

• Work closely with AI engineers to build infrastructure for LLM/RAG pipelines, vector DBs, and real-time AI decisioning
• Implement backend support for prompt orchestration, Langchain flows, and function-calling interfaces
• Support model deployment, inference APIs, and logging/monitoring for large-scale GenAI pipelines

Database & Storage Design

• Optimize database design and queries using MySQL, PostgreSQL, and MongoDB
• Architect and manage Redis and Kafka for caching, queueing, and real-time communication

DevOps & Quality

• Ensure continuous delivery through version control (Git), CI/CD pipelines, testing frameworks, and Docker-based deployments
• Identify and resolve bottlenecks related to performance, memory, or data throughput
• Adhere to best practices in code quality, testing, security, and documentation
• Mentor junior developers and participate in code reviews
• Collaborate cross-functionally with product, AI, design, and sales engineering teams
• Contribute to architectural decisions, roadmap planning, and scaling strategies

Qualifications

• 4–8 years of backend development experience in Python, with a deep understanding of object-oriented and functional programming
• Hands-on experience with FastAPI, Django, or Flask in production environments
• Proven experience building scalable microservices, data pipelines, and backend systems that support live applications
• Strong command over REST API architecture, database optimization, and data modeling
• Solid experience working with web scraping tools, automation frameworks, and external API integrations
• Knowledge of AI tools like Langchain, HuggingFace, Vector DBs (Pinecone, Weaviate, FAISS), or RAG architectures is a strong plus
• Familiarity with cloud infrastructure (AWS/GCP), Docker, and containerized deployments
• Comfortable working in fast-paced, high-ownership environments with shifting priorities and dynamic problem-solving

Bonus

• Prior experience in an early-stage SaaS startup or AI-first product environment
• Contributions to open-source Python projects or developer communities
