Position Overview

We are seeking an experienced AI-Focused Full-Stack Developer based to architect, build, and deploy intelligent software applications. In this role, you will combine traditional full-stack web engineering with modern AI capabilities—building custom RAG pipelines, deploying AI agentic workflows, connecting LLM APIs, and embedding AI-driven automation into operational platforms.

You will collaborate directly with our team to turn business workflows into fast, scalable, AI-powered web applications.

Key Responsibilities

AI & LLM Integration

Design and implement intelligent features using OpenAI (GPT-4o), Anthropic (Claude), open-source LLMs, and API integrations.

RAG & Agentic Workflows

Build Retrieval-Augmented Generation (RAG) systems, autonomous AI agents, and custom workflow automations using frameworks like LangChain, LlamaIndex, or CrewAI.

Database & Vector Search

Design, manage, and query relational databases (PostgreSQL, MySQL) and vector databases (Pinecone, Qdrant, Supabase pgvector) for semantic document retrieval and memory stores.

Full-Stack Application Engineering

Develop responsive front-end interfaces (React, Next.js, or Vue) and robust back-end APIs (Python FastAPI/Flask, Node.js, or TypeScript).

Optimization & Performance

Implement effective prompt engineering strategies, evaluate model latency and API costs, and optimize database queries for high reliability.

Daily Agile Execution

Participate in daily stand-ups, maintain clean Git workflows, write automated unit tests, and provide regular progress updates via Slack and Jira/Asana.

Required Technical Skills & Experience

Professional Experience

4+ years in software engineering, with at least 1.5+ years of hands-on experience building production applications using AI models and LLMs.

AI & Machine Learning Ecosystem

o Frameworks

Hands-on experience with LangChain, LlamaIndex, or raw LLM API tool calling/function execution.

o Vector Stores

Experience working with Pinecone, Chroma, Supabase (pgvector), or Weaviate.

o Prompting & Fine-Tuning

Deep understanding of prompt engineering, function calling, agentic loops, and model evaluation.

Core Tech Stack

o Back-End

Strong proficiency in Python (FastAPI, Django) or TypeScript/Node.js.

o Front-End

React.js, Next.js, or Vue.js.

o Version Control & Cloud

Git, GitHub/GitLab, Vercel, Docker, AWS, or GCP.
