Overview

We’re seeking a talented Full Stack Java Engineer who is a true utility player equally comfortable modernizing legacy systems, building React front-ends, and integrating AI-driven workflows into enterprise applications. This is not a specialized AI/ML role, but rather an opportunity for a strong, adaptable full-stack generalist to grow across an evolving technology landscape.

What You’ll Do

• Design, develop, and enhance enterprise-grade applications across Java backend and React frontend
• Modernize legacy Java systems while building scalable improvements
• Build and support client-facing portals using modern frameworks
• Integrate AI and agentic capabilities into existing business workflows
• Develop lightweight Python-based automation and AI integrationsContribute to technical design, system architecture, debugging, and performance optimization
• Collaborate across teams in a polyglot engineering environment

What We’re Looking For Core Requirements

Full-Stack Mastery

• Strong hands-on Java backend development experience
• Proven track record building complex full-stack applications
• Expert-level React.js or modern front-end framework experience
• Comfort navigating legacy and modern enterprise architectures across the entire stack

Engineering Versatility

• Ability to work across multiple languages and technology stacks
• Strong fundamentals with genuine adaptability to evolving technologies
• Utility-first mindset, not a narrow specialist

AI/Agentic Exposure (Secondary, But Important)

• Experience integrating AI or agentic workflows into business applications; practical Python development; building AI-assisted systems (e.g., OCR + LLM-driven document extraction, intelligent validation, agentic orchestration)
• Nice-to-have: Familiarity with Foundry-like or agentic development environments
• Not required: AI/ML research expertise, deep model training, or Python-only backgrounds

What We Won’t Consider

• Pure Java engineers unwilling to expand beyond backend
• Pure AI/ML specialists without strong full-stack capability
• Highly narrow specialists with limited cross-technology adaptability

The Ideal Candidate

You’re an exceptional Java + React full-stack engineer who:

• Thrives as a generalist across diverse and evolving systems
• Brings practical AI/agentic integration experience
• Can learn and grow into emerging LLM ecosystems
• Values breadth and adaptability over deep specialization
• Operates confidently in fast-moving technical environments
