Structured Data

↓

AI Agent Decision / Output

Experience should include

- PostgreSQL MCP integration

- Database querying through MCP

- Schema understanding

- Tables and relationships

- CRUD operations where appropriate

- SQL

- Data retrieval

- Data validation
- AI-to-database workflows

- Database security

- Error handling

Candidates without practical PostgreSQL + MCP integration experience should not be considered for this role. ? API INTEGRATION — MUST HAVE

Strong hands-on experience in API integration with AI agents is mandatory.

The engineer must be comfortable with:

- REST APIs

- JSON

- API authentication

- API keys

- OAuth where applicable

- Webhooks

- API requests/responses

- Error handling

- Retry mechanisms

- Rate limiting

- Data transformation

- API testing

- API debugging

Required understanding AI Agent → MCP Tool → API → External System → Response → AI Agent The engineer should be able to independently troubleshoot failures across this entire chain.

? 60 AI AGENT ARCHITECTURE The core project is to create a scalable architecture for:

60 SECTORS = 60 AI AGENTS

Each sector gets one specialised AI Agent.

For example

Sector 01 AI Agent

Sector 02 AI Agent

Sector 03 AI Agent

...

Sector 60 AI Agent

However, the objective is not to build 60 completely different systems.

The engineer must create a:

REUSABLE AI AGENT ARCHITECTURE where the underlying architecture, tools, MCP patterns, database integration, API framework,



monitoring and deployment model can be reused across all 60 sector agents.

? IGEN NEWS — AI AGENT APPLICATION
