Senior Software Engineer (Full Stack – Next.js + FastAPI + AI Agents)

Experience : 2+ years

Location : Gurgaon (Onsite)

Type : Full-Time

Tech Stack : Next.js 14

  • FastAPI
  • LangChain
  • PostgreSQL
  • Pandas
  • OpenAI

About the Role

We’re building the next-generation AI-driven financial intelligence platform -blending clean frontend design, high-performance backend systems, and autonomous AI agents that reason over financial documents.

As a Senior Software Engineer (Full Stack), you’ll take ownership across the stack -from architecting scalable APIs and building interactive dashboards to integrating advanced LLM agents using LangChain and OpenAI APIs.

You’ll work on real-world data (SEC filings, financial statements, analytics pipelines) and bring agentic intelligence to life in production.

Tech Stack Overview :

Layer : Core Technologies

Frontend : Next.js 14 (App Router), React 18, TypeScript, Tailwind CSS, shadcn / ui, React Query, Zustand, framer Motion

Backend : FastAPI, Uvicorn, Gunicorn, Pandas, Pydantic, SQLAlchemy, PostgreSQL

AI / Agentic Layer : LangChain, LlamaIndex, OpenAI / Anthropic APIs, Chroma / Weaviate

Developer Tooling : Docker, Git (Bitbucket), Postman / Bruno, VS Code, JupyterLab

What You’ll Build

  • Full-Stack Web Apps :
  • Build rich, performant web applications using Next.js 14, TypeScript, and Tailwind.
  • Integrate FastAPI endpoints for analytics, document uploads, and agent workflows.
  • Agentic AI Workflows :
  • Design and implement LangChain-based AI agents that can :
  • Parse and summarize SEC filings (10-K, 10-Q)
  • Extract and clean tabular data with Pandas
  • Stream results live via WebSockets or SSE
  • Backend APIs & Data Pipelines :
  • Develop high-performance FastAPI endpoints using async I / O, SQLAlchemy ORM, and PostgreSQL.
  • Orchestrate data transformation and ETL flows using Pandas and Openpyxl.
  • LLM & RAG Integration :
  • Integrate GPT-4 / Claude 3.5 models for financial analysis, text synthesis, and document retrieval using LlamaIndex or LangChain.
  • Secure & Scalable Architecture :
  • Implement JWT-based auth (or NextAuth), containerize with Docker, and deploy production-ready services behind Nginx.

    • Key Responsibilities

  • Architect and develop end-to-end product features across frontend, backend, and AI layers.
  • Design and optimize ETL pipelines for financial data ingestion and transformation.
  • Build modular, type-safe frontend components using shadcn / ui and TypeScript.
  • Develop and maintain REST & WebSocket APIs for real-time streaming.
  • Integrate AI models (OpenAI / Anthropic) via LangChain agents.
  • Collaborate on database design, migrations, and ORM logic in PostgreSQL.
  • Ensure clean, maintainable, and well-documented code following modern dev standards.
  • Participate in code reviews, system design discussions, and deployment automation.

    • Desired Skills & Expertise

    Frontend :

  • Strong grasp of React, Next.js 13 / 14, TypeScript, and React Query / Zustand
  • Deep understanding of Tailwind CSS, shadcn / ui, and component-driven design

    • Backend :

  • Proficient in FastAPI, Pandas, SQLAlchemy, and PostgreSQL
  • Solid knowledge of asynchronous Python, Pydantic, and REST API design

    • AI Layer :

  • Hands-on experience with LangChain, LlamaIndex, or RAG pipelines
  • Familiarity with OpenAI / Anthropic SDKs and agentic workflows

    • Bonus Points :

  • Experience with Docker and cloud deployment (AWS / GCP)
  • Familiarity with Vector Databases (Chroma, Weaviate, FAISS)
  • Understanding of financial data, SEC filings, or quantitative analytics
  • Background in LLM orchestration or AI tool-building

    • 🎯 What Success Looks Like

  • You ship production-grade features end-to-end -from frontend UI to backend APIs.
  • You optimize agentic workflows that handle real-time document parsing and summarization.
  • You write efficient, reusable code that’s both clean and elegant.
  • You demonstrate ownership -solving complex data problems without constant oversight.
  • You contribute to an ecosystem that merges engineering + data + intelligence seamlessly.

    • 🌍 Why Join Us

  • Build the first-of-its-kind AI financial research platform used by analysts, investors, and institutions.
  • Work directly on real agentic AI systems (LangChain + FastAPI)
  • Freedom to own architecture, make decisions, and ship impact.
