It is vital that you have

• fluency in English (min. C1)
• 5+ years in software/platform engineering with recent production LLM applications (not just prototypes)
• hands‑on expertise with agentic frameworks (one or more of: LangGraphမိဳ/ LangChain Agents, AutoGen, CrewAI, LlamaIndex Agents, Semantic Kernel, Haystack Agents) and tool/function‑calling patterns
• strong RAG engineering across vector DBs, chunking/embedding strategies, metadata/search ranking, and grounding techniques
• proven(es) track record building observable, cost‑aware, and secure LLM systems (tracing, evals, guardrails, secrets/IAM, PII handling)
• solid software engineering fundamentals: Python/TypeScript, async patterns, APIs, testing, CI/CD, containerization
• clear communicator who can interface with clients and write crisp technical docs
• working in agile methodologies (Scrum, Kanban)
• eager to learn and share knowledge

Nice to have

• cross‑cloud vender exposure (AWS/GCP) and hybrid integrations; experience with enterprise connectors (SharePoint/OneDrive, ServiceNow, Salesforce)
• experience with structured output, constrained decoding, JSON Schemas, and program‑of‑thought planning
• Python
• TypeScript
• LLM
• LangGraph / LangChain Agents
• CI/CD

You will be responsible for supporting our team in

• design and implement modular AI agents with robust state management, memory, and routing using frameworks like LangChain/LangGraph, Microsoft AutoGen, CrewAI, LlamaIndex, Semantic Kernel, and Haystack
• build reusable components including planners, tool registries, policy guards, and evaluators, integrated across clients and domains
• connect agents to enterprise tools and data sources via APIs, webhooks, queues and event‑driven flows
• implement retrieval‑augmented generation (RAG) with vector and structured stores (pgvector, Pinecone, Weaviate, SQL, Graph), ensuring reliability with fallbacks, circuit breakers, and caching
• define SLIs/SLOs, implement metrics, logging and tracing (e.g., Langfuse, OpenTelemetry), and develop evaluation harnesses (automatic and human‑in‑the‑loop) to measure task success, safety and costviens
• productionize agents using CI/CD, feature flags, and canary deployments, optimizing cost‑per‑task and time‑to‑success
• apply policy‑as‑code, data redaction, role/tenant isolation, and data minimization, collaborating with security teams to meet ISO 27001, SOC 2, NIST, HIPAA and GDPR requirements
• translate business processes into agentic solutions and create domain‑specific agents and reusable templates for enterprise workflows
