Senior Tech Mobile Agentic AI Developer

Core Technical Must-Haves

• 10+ years of software development experience with strong Python expertise in production environments
• 2+ years hands-on LLM development using LangChain, LangGraph, or equivalent frameworks
• Hands-on RAG pipeline experience (embeddings, vector search, re-ranking, answer generation)
• Experience with LLM APIs (OpenAI Chat Completions / Responses API, streaming, tool calling)
• Strong async Python skills (asyncio, httpx, FastAPI)
• Prompt engineering experience (system prompts, few-shot, structured JSON output)
• Experience with resilient design patterns (circuit breakers, retry logic, fallback chains)
• PostgreSQL + async ORMs (SQLAlchemy async / Alembic)
• Git, CI/CD, Docker, and Kubernetes basics
• Strong system design skills (microservices, distributed systems, API design)

. Key Role Responsibilities Fit

• Experience designing & developing LLM-powered agents and multi-agent orchestration pipelines (conditional routing, state management, error recovery)
• Built real-time streaming capabilities (WebSocket / SSE) for conversational AI
• Implemented tool-calling agents (parallel API execution, sequential enrichment, summarization)
• Experience with multi-modal AI features (vision models / image analysis) is a plus
• Writes production-quality Python code (error handling, logging, observability, unit tests)
• Comfortable participating in code reviews, architecture discussions, and sprint delivery

. Nice-to-Have Skills (strong differentiators)

• Deep LangGraph experience (StateGraph, conditional edges, node pipelines, compiled graphs)
• Multi-agent systems (orchestration, routing, RBAC-based access control)
• LLM observability tools (Langfuse or similar – tracing, token usage, latency)
• WebSocket and SSE streaming protocols
• Multi-modal AI (vision models, image analysis)
• Vector databases (OpenSearch, Pinecone, pgvector)
• AWS services (Aurora PostgreSQL, SSM, IAM, EKS)
• Telecommunications or field service domain experience

. Tech Stack Alignment

• Python 3.11+
• FastAPI, LangChain, LangGraph
• Azure OpenAI (GPT-4)
• PostgreSQL (Aurora), OpenSearch (vector)
• WebSocket, SSE, REST
• Observability: Langfuse, Datadog, Splunk
• Docker, Kubernetes (EKS), AWS
• GitLab CI, Helm, ArgoCD
• pytest / unittest

. Soft Skills & Delivery Style

• Hands-on production developer (not just prototyping)
• Ability to work closely with platform architect on core multi-agent orchestration
• Experience building systems that serve real users at scale (this platform handles 40,000+ daily interactions)
