Full Stack Engineer (Java + React)

Building the Next Generation of Agentic AI Platforms

My client is building the next generation of agentic platforms and AI-powered enterprise systems.

Why This Role

As a Staff Full-Stack Engineer, you won't just ship features—you'll architect the core systems that power intelligent workflows at scale. You'll design both the brains and nervous system of the platform: robust Java backend services paired with high-quality React.js interfaces.

What You’ll Do

• Design, build, and scale end-to-end full-stack systems.
• Architect backend services in Java (Spring Boot / microservices) REST APIs.
• Asynchronous workflows.
• Distributed state management.
• Build modern frontend applications using React.js + TypeScript.
• Integrate LLM-based agents, RAG pipelines, vector stores, and orchestration workflows.
• Define and own API contracts for frontend, third-party, and enterprise integrations.
• Ensure system performance, reliability, observability, and security.
• Champion clean architecture, testing strategies, CI/CD, and documentation.
• Influence platform-level architecture decisions.
• Mentor engineers and elevate engineering standards across the team.

What You Bring

• 9+ years of full‑stack engineering experience.
• Strong expertise in Java (Spring Boot / microservices).
• Deep experience building applications with React.js.
• Experience with REST APIs, PostgreSQL, Redis, Kafka (or similar event systems).
• Strong frontend architecture and performance optimization skills.
• Hands‑on experience with GCP, Docker, and CI/CD pipelines.
• Comfort operating in 0‑to‑1 and fast‑scaling startup environments.
• Strong communication skills and cross‑functional collaboration ability.
• Ownership mindset with a passion for building high‑quality systems.
