**Job overview:**

Build and operate scalable backend and AI platforms, with Python as the primary language. The role owns production Retrieval-Augmented Generation (RAG) and agentic capabilities across APIs, data, infrastructure and user-facing workflows, while welcoming strong engineers with relevant experience in Go, Java, Node.js or other modern technology stacks.

**Key Responsibilities:**

• Develop and maintain backend and AI-platform services, primarily in Python; use Go, Java, Node.js or other suitable technologies when they improve performance or reliability.
• Deliver document ingestion and processing, chunking, embeddings, vector/hybrid search, retrieval and reranking, context management, prompt optimization and quality evaluation.
• Build multi-agent orchestration, MCP, A2A, tool integration, state/task coordination, and integrations with LLM providers such as OpenAI and Anthropic.
• Create REST/GraphQL APIs, microservices and event-driven workflows; integrate SQL, NoSQL, vector databases and third-party services.
• Improve concurrency, asynchronous processing, caching, Kafka-based messaging, observability and large-scale data processing.
• Apply automated testing, code review, documentation, security practices, CI/CD, Docker/Kubernetes, cloud and infrastructure as code.
• Partner with AI/ML, Product, Design and Frontend teams; mentor engineers and evaluate emerging AI technologies.

**Requirements:**

• Bachelor's degree in Computer Science, Software Engineering or a related field, with 5+ years of backend or full-stack software development experience.
• Strong production Python and clean-code skills; experience with one or more of Go, Java, Node.js or comparable backend languages; sound knowledge of concurrency, threading and event loops.
• Hands-on experience with FastAPI, Flask or equivalent frameworks; REST/GraphQL, microservices, event-driven architecture, system design, SOLID principles and design patterns.
• Hands-on delivery of RAG/LLM systems covering document processing, embeddings, semantic/vector/hybrid search, retrieval, context and prompt engineering, LLM-provider integration, multi-agent orchestration and MCP/A2A; experience with LangChain, LlamaIndex, AutoGen or CrewAI is valued, and 2+ years in AI platforms, RAG or agents is preferred.
• PostgreSQL/MySQL, Redis/MongoDB, vector stores such as Qdrant, Pinecone, Weaviate or Milvus, plus Kafka and asynchronous processing.
• Git, Docker, Kubernetes and CI/CD; AWS/GCP/Azure and Terraform/CloudFormation experience are preferred.
• Unit/integration/edge-case testing, OWASP, rate limiting, logging, token management, monitoring/observability, debugging and performance optimization; strong communication and mentoring. React or Vue.js experience is a plus.
