Full Stack Developer

Stefanini Group is a global provider of IT consulting and outsourcing services. They are seeking a Full Stack Developer to focus on building AI/agentic systems for an Enterprise Data Platform, emphasizing multi-agent orchestration on Google Cloud Platform.

Responsibilities:

• Architecture: Design multi-agent AI systems, evaluate trade-offs (single vs. multi-agent, RAG vs. fine-tuning), and contribute to Architecture Decision Records
• Hands-on Coding: Daily production-grade code across agent frameworks, backend/frontend, and LLM-powered workflows (NL-to-SQL, semantic search, metadata enrichment), plus guardrails and observability for AI outputs. Familiarity with Agentic coding tools like opencode, Claude code, etc., is expected
• Full-Stack Work: Backend (Python/FastAPI) and frontend (Angular/React) development, chat and API interfaces, and evaluation/benchmarking tools, with end-to-end feature ownership
• Engineering Excellence: Maintain high code quality, lead by example in reviews, conduct root-cause analysis on agent failures, and act as the team's technical anchor for tough problems
• Collaboration: Work with Product, Data Engineering, and Platform teams; mentor others, support sprint planning, and help onboard new hires. In short, the role combines deep technical architecture responsibility with daily hands-on coding, centered on building robust, scalable multi-agent AI systems and serving as the team's go-to technical expert
