Job summary

ACCENTURE SG SERVICES PTE. LTD. is seeking a hands-on Full Stack AI Consultant (Developer) to join its enterprise AI delivery capability.

You will build full stack agentic AI applications using Python backends, REST and event-driven APIs, and React frontends, delivering production-grade solutions under senior technical leads. The role emphasizes active daily engineering: writing code, building agents, implementing MCP servers, designing knowledge pipelines, and maintaining DevOps/AgentOps

Qualifications

• Experience building production-grade full stack AI applications.
• Strong programming skills in Python and modern frontend frameworks.
• Experience designing and implementing API-driven, scalable systems.

Responsibilities

• Design and build full stack agentic AI applications — Python backends, REST and event-driven APIs, and React or equivalent frontends — to production engineering standards.
• Implement agentic application UX: streaming responses, intermediate output display, reasoning transparency, and error and escalation interfaces for end users.
• Translate business requirements into technical specifications; work with managers and clients to clarify scope, surface ambiguities, and deliver against agreed outcomes.
• Build and configure agents using orchestration frameworks; harness setup, persona and instruction loading, tool binding, memory configuration, and lifecycle management.
• Implement reasoning patterns appropriate to each agent use case; design and version prompt architecture including system prompts, few-shot examples, and structured output schemas.
• Build multi-agent workflows— defining agent roles, A2A handoff contracts, shared state schemas, and escalation paths — under architectural guidance from technical leads.
• Design, build, and maintain MCP servers connecting agents to enterprise systems, APIs, databases, and SaaS platforms.
• Translate business processes into agent-executable skills, structured instructions, and reusable workflows.
• Implement context engineering pipelines, memory architectures, and LLM gateway configuration to support reliable, cost-efficient agent operation.
• Build RAG pipelines: document ingestion, chunking, embedding, vector store indexing, hybrid retrieval, re-ranking, and quality evaluation.
• Implement Text-to-SQL capabilities — schema grounding, query generation, validation, and safe execution against enterprise databases.
• Integrate Elasticsearch as a retrieval backend; build knowledge graph components and ontology-driven query layers.
• Maintain CI/CD pipelines for agent code, prompt changes, and infrastructure.
• Instrument agentic systems with production observability: tracing, cost tracking, latency profiling, failure logging, and drift detection.
• Build agent testing suites and guardrails; manage versioned registries of agents, tools, skills, prompts, and workflows.
