AI Engineer

PAYU PAYMENTS PRIVATE LIMITED

AI EngineerCompany: PayU Finance India | Experience: 4–7 years | Location: India — Hybrid (Gurugram / Bangalore)

| Type: Full-time, IC`

About The Role

We need an AI Engineer who ships production AI systems — not prototypes. You'll build AI-powered backend services, autonomous agents, and intelligent integrations that directly impact lending decisions and operational e ciency.

You own the full lifecycle — from evaluating a new LLM capability to deploying an agent that handles real tra c with real financial consequences.

Prior hands-on experience building and deploying AI-powered systems in production is a must.

What You'll Do

Build AI Systems

Deploy AI agents for lending workflows — document verification, bureau analysis, risk assessment, customer communication
Build MCP servers and tool integrations extending AI across internal systems
Implement RAG pipelines over lending policies, regulatory docs, and knowledge bases
Develop function-calling and tool-use patterns for safe LLM interaction with databases and APIs
Build evaluation and guardrail frameworks to catch hallucinations and enforce compliance

Engineer the Backend

Architect scalable services using Java, Spring Boot, and Python for production AI features
Design schemas using SQL and NoSQL databases optimized for AI workloads
Build RESTful APIs serving model inference at low latency and high throughput
Integrate with credit bureaus, banking partners, and payment gateways Raise the Bar

Code reviews for AI patterns and security, optimize token costs and latency, establish AI observability, and drive AI-assisted development (Cursor, Copilot) across the team.

Review and validate AI-generated code for correctness, security, and project standards. Build test suites, guardrails, and eval frameworks for prompts and agent behaviors — with continuous benchmarks, drift detection, and human-in-the-loop review before production.
