Apollo Logic

Location: Delhi (Onsite at least 3 days/week ) Experience: 2–3+ years About the Role We are building an AI-first SaaS product that combines modern web apps with Retrieval-Augmented Generation (RAG) and agentic workflows. You will ship end‑to‑end features across a React front end and Node.js/Python back end, integrate vector databases, and help productionize LLM-driven experiences that are fast, reliable, and secure. What You’ll Do Build rich, responsive UIs in React (TypeScript preferred) with clean component architecture, state management, and accessible design. Design, build, and document REST/GraphQL APIs using Node.js (Express/Nest) and Python (FastAPI/Flask) Implement RAG pipelines: chunking, embeddings, indexing, and retrieval using vector databases (e.g., pgvector/Postgres, Pinecone, Weaviate, Milvus, Qdrant) Contribute to agentic workflows (LangGraph/LangChain/LlamaIndex) for autonomous or tool‑using task flows with evals and guardrails. Design event‑driven components with Kafka/RabbitMQ/SQS Stand up observability (logs, metrics, traces) and performance budgets; drive profiling and capacity planning. Key Skill-Set Front End: React, TypeScript, Next.js/Vite, Tailwind/MUI, React Query/SWR, form libs (React Hook Form/Zod) Back End: Node.js (Express/Nest) and Python (FastAPI/Flask) as primary; exposure to Go or Java (Spring Boot) is a plus. Inter‑service APIs: REST/GraphQL, gRPC + Protobuf for low‑latency internal calls; WebSockets/SSE for realtime features. Data & Infra: Postgres (+ pgvector ), Redis, object storage (S3‑compatible), CDN/edge caching; message queues/streams (Kafka/RabbitMQ/ AWS SQS/SNS ); search (Elasticsearch/ OpenSearch ) Vector DBs: Pinecone / Weaviate / Milvus / Qdrant / pgvector (any one strongly preferred) AI/Agents: LangChain, LangGraph, LlamaIndex; model gateways DevOps & Platform: Docker; Kubernetes (EKS/GKE/AKS) or ECS/Fargate ; API Gateway/ALB/Nginx; CI/CD (GitHub Actions/GitLab CI) Job Types: Contractual / Temporary, Freelance Contract length: 6 months Pay: ₹400,000.00 - ₹1,500,000.00 per year Benefits: Flexible schedule Paid sick time Work Location: In person
