About the Role

We are seeking an innovative Full Stack Software Engineer with specialized expertise in Artificial Intelligence to drive the development of our next-generation applications. In this role, you will own the end-to-end lifecycle of new features, building highly scalable Java backends and dynamic React frontends while integrating cutting-edge LLMs and AI frameworks.

You will be expected to make critical architectural decisions, balance model trade-offs (cost, latency, accuracy), and leverage AI-assisted tooling to accelerate development.

Key Responsibilities

• End-to-End Engineering: Architect, build, and deploy robust full-stack solutions, designing everything from the data model and API structure to the user interface flow.
• Backend Development: Build scalable APIs, microservices, and batch-processing systems utilizing Java.
• Frontend Development: Own and develop intuitive, responsive UIs for dashboards, internal tools, and public-facing applications using React.
• AI & LLM Integration: Design and implement AI-powered features (e.g., RAG systems, AI agents, chatbots, recommendation engines) into production environments.
• Model Management: Evaluate, select, and integrate appropriate AI models (OpenAI, Anthropic Claude, Gemini, Llama) and handle optimization for latency, accuracy, and operational cost.
• Modern Workflows: Utilize modern AI-assisted development tools (e.g., Cursor, GitHub Copilot, Claude Code) to improve code quality, validate outputs, and enhance engineering velocity.

Required Skills & Qualifications

• Backend Expertise: Strong professional experience in Java ecosystem architecture and microservices development.
• Frontend Expertise: Proven track record of owning frontend architecture and delivering complex UIs in React.
• AI/ML Frameworks: Hands-on experience with the modern AI stack, including LangChain, LlamaIndex, Hugging Face, and Vector Databases.
• System Design: Exceptional ability to conceptualize new services from the ground up, making sound architectural choices across the entire stack.
• Problem Solving: Demonstrated ability to navigate the unique technical challenges of AI implementation, including prompt engineering, context window limits, and output validation.
