6. AI Agent Developer
AI agents can perform tasks, use tools, and interact with external systems.
An AI agent developer may work on:
Agent workflows
Tool calling
Memory systems
Task planning
API integrations
Permissions
Error handling
Agent evaluation
AI Agent Development often requires more than simply connecting an LLM to an application because the agent may be expected to make decisions and execute actions.
For example, a business agent might retrieve customer information, update a CRM, create a support ticket, and notify an employee.
Each action introduces additional engineering and security considerations.
7. Backend Developer
AI applications still require conventional software engineering.
Backend developers can build:
APIs
Authentication
Databases
Business logic
Integrations
User management
Data services
They also connect AI components to the rest of the application.
For example, an AI assistant may need to access a company's customer database. The backend layer controls how that information is retrieved and presented to the AI system.
8. Frontend and UX Specialists
AI functionality needs an effective user experience.
Frontend developers and UX specialists may design:
Chat interfaces
AI dashboards
Recommendation interfaces
Workflow screens
Analytics dashboards
User feedback mechanisms
An AI system can be technically advanced but still fail to gain adoption if users find it confusing or difficult to use.
9. DevOps and Cloud Engineer
AI applications require infrastructure that can support development and production workloads.
DevOps and cloud specialists may handle:
Cloud deployment
CI/CD pipelines
Infrastructure automation
Monitoring
Scaling
Security
Logging
Cost optimization
This becomes particularly important when AI applications experience high usage or require significant computing resources.
10. QA and AI Evaluation Specialists
Testing AI applications requires more than checking whether buttons and APIs work correctly.
QA teams may evaluate:
Functional behavior
AI response quality
Accuracy
Edge cases
Security
Performance
User experience
Failure scenarios
AI evaluation should also test how the system behaves when it receives unexpected or ambiguous input.
