Job description

Python Backend Developer AI Platform

Experience: 1 – 4 Years | Product Company | Enterprise HRTech Platform

Role Summary

We're looking for a strong Python Backend Developer to join our enterprise HRTech/LMS platform team. You'll build APIs and backend services that power the product, and get direct exposure to Generative AI features such as AI assistants, document search, and RAG-based knowledge tools. You'll build features used by leading enterprises across hiring, learning, employee engagement, and HR automation.

You will build new AI-powered product capabilities.

Prior hands-on GenAI experience is a plus, not a requirement. If you're a solid Python developer with curiosity about LLMs and AI — even from a personal project, hackathon, or self-learning — we want to9 hear from you.

What You'll Work On

• Enterprise HRTech platform (LMS/HRMS modules)
• FastAPI-based microservices
• OpenAI APIs & LangChain-based features
• Retrieval-Augmented Generation (RAG) and AI agents
• Resume intelligence & document search
• LLM integrations for product features
• Product development

Key Responsibilities

• Develop backend services, APIs, and business logic in Python (FastAPI, Flask, or Django).
• Design and maintain modules for user management, workflows, reports, notifications, and document handling.
• Work with SQL databases; write and optimise queries.
• Write clean, reusable, well-documented, and testable code.
• Collaborate with product, QA, frontend, and AI teams to ship features end-to-end.
• Contribute to AI-powered modules (chatbots, search, recommendations, document processing) alongside senior engineers — full ownership grows with experience.
• Work with senior developers on integrating Python services with our existing Java-based systems.

Mandatory Skills

• Strong hands-on Python programming — OOP and data structures.
• Experience building REST APIs with FastAPI, Flask, or Django.
• Working knowledge of SQL (MySQL/PostgreSQL).
• Good understanding of Git/version control.
• Solid programming fundamentals, debugging, and problem-solving ability.

Preferred Skills (Good to Have)

You don't need to tick every box below — these are things we're happy to teach, and any exposure is a bonus:

• Exposure to OpenAI APIs, LangChain, or Hugging Face.
• Basic understanding of RAG, embeddings, or vector search (FAISS, Chroma, Pinecone).
• Interest in or basic exposure to prompt engineering.
• Familiarity with Pandas, NumPy, or Scikit-Learn.
• Basic Docker knowledge.
• Ability to read Java or Spring Boot code (not required to write it).
• Exposure to background jobs, Celery, Redis, or schedulers.
• Familiarity with cloud platforms (AWS, Azure, or GCP).

Experience Required

• 1–4 years of experience in Python backend development.
• Candidates with a GitHub portfolio, personal AI projects, hackathon experience, or internships are welcomed even without formal AI job experience.
• 3–4 year backend developers looking to move into AI-focused product work are strongly encouraged to apply.

Educational Qualification

B.E. / B.Tech / MCA / M.Sc. in Computer Science, IT, or a related field. Equivalent practical experience and a strong project portfolio will also be considered.

Why Join Us

• Work on cutting-edge AI product features, not legacy maintenance.
• Direct, hands-on exposure to LLMs and Generative AI tooling.
• Learn from experienced product architects and senior engineers.
• High ownership with fast-tracked career growth.
• Product-based development for an enterprise platform used by large clients.
