Fullstack Developer - Spring, Angular 4+, AWS

We’re partnering with a fast-growing AI-first enterprise transforming how organizations handle documents, decisioning, and workflows — starting with BFSI and healthcare. Their platforms are redefining document intelligence, credit analysis, and underwriting automation using cutting-edge AI and human-in-the-loop systems.

As an AI Engineer, you’ll work with a high-caliber engineering team building next-gen AI systems that:

• Power robust APIs and platforms used by underwriters, analysts, and financial institutions.
• Build and integrate GenAI-powered agents.
• Enable “human-in-the-loop” workflows for high-assurance decisions in real-world conditions.

Key Responsibilities

• Build and optimize ML/DL models for document understanding, classification, and summarization.
• Apply LLMs and RAG techniques for validation, search, and question-answering tasks.
• Design and maintain data pipelines for structured and unstructured inputs (PDFs, OCR text, JSON, etc.).
• Package and deploy models as REST APIs or microservices in production environments.
• Collaborate with engineering teams to integrate models into existing products and workflows.
• Monitor, retrain, and fine-tune models to ensure reliability and performance.
• Stay updated on emerging AI frameworks, architectures, and open-source tools; propose system improvements.

Required Skills & Experience

• 2–5 years of hands-on experience in AI/ML model development, fine-tuning, and deployment.
• Strong Python proficiency (NumPy, Pandas, scikit-learn, PyTorch, TensorFlow).
• Solid understanding of transformers, embeddings, and NLP pipelines.
• Experience with LLMs (OpenAI, Claude, Gemini, etc.) and frameworks like LangChain.
• Exposure to OCR, document parsing, and unstructured text analytics.
• Familiarity with FastAPI/Flask, Docker, and cloud environments (AWS/GCP/Azure).
• Working knowledge of CI/CD pipelines, model validation, and evaluation workflows.
• Strong problem-solving skills, structured thinking, and production-quality coding practices.

Bonus Skills

• Domain exposure to Fintech/BFSI or Healthcare (e.g., credit underwriting, claims automation, KYC).
• Experience with vector databases (FAISS, Pinecone, Weaviate) and semantic search.
• Knowledge of MLOps tools (MLflow, Airflow, Kubeflow).
• Experience integrating GenAI into SaaS or enterprise products.

Education

• B.Tech / M.Tech / MS in Computer Science, Data Science, or related field.
• (Equivalent hands-on experience will also be considered.)

Why Join

• Build AI systems from prototype to production for live enterprise use.
• Work with a senior AI and product team that values ownership, innovation, and impact.
• Exposure to LLMs, GenAI, and Document AI in large-scale enterprise environments.
• Competitive compensation, career growth, and a flexible work culture.

Note: We are looking for real, hands-on experience—not certifications or copy-paste portfolios. Selected candidates will be given a short real-world task to evaluate skills before interview.

Key Responsibilities

• Design, build, and maintain scalable full-stack applications using MongoDB, Postgresql, Express.js, React.js, and Node.js
• Develop RESTful APIs and integrate them with frontend systems
• Collaborate with designers and project managers for timely project delivery
• Optimize code for performance and scalability
• Troubleshoot, debug, and upgrade applications as needed
• Follow Git-based workflows for version control

Must-Have Skills

• Strong hands-on experience in:
• React.js with hooks, context API, component architecture
• Node.js with Express.js
• MongoDB (CRUD operations, schema design) & Postgresql
• API development and integration
• Strong JavaScript fundamentals (ES6+)
• Basic understanding of deployment (e.g., cPanel, Vercel, Heroku, or VPS)
• Git and GitHub for code versioning

Good-to-Have Skills

• Knowledge of Redux or any other state management tools
• Experience with Next.js or TypeScript
• Familiarity with Tailwind CSS or Material UI
• Experience integrating third-party APIs (e.g., payment gateways, social logins)

Who Should Apply

• You’ve worked on real client projects or have built and shipped working applications.
• You are disciplined and take ownership without constant follow-up.
• You are not here to "fake it till you make it"—you’re here to grow with a real team.
