Why This Role

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

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:

• 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
