QA Engineer - Agentic Gateway Testing
Location: Remote from Spain (an indefinite Spanish employment contract)

We are looking for a QA Engineer specializing in Agentic Gateway Testing to ensure the reliability, security, performance, and observability of agentic workflows and tool integrations. The role focuses on testing MCP-based interactions, multi-step agent workflows, authorization controls, performance characteristics, and end-to-end traceability across an enterprise agentic platform.
About the Client
Our client is a large general enterprise operating across multiple markets, with a complex technology landscape and a strong focus on digital transformation and innovation. The organization is actively investing in modern cloud, data, and AI capabilities to enable scalable, secure, and highly automated solutions across its business.
About the Project
The project is focused on building an enterprise-grade AI Agent Platform from the ground up. The platform will provide a standardized foundation for developing, deploying, orchestrating, securing,



and observing AI agents across multiple teams and use cases.
The initiative covers the full agent lifecycle and brings together agent orchestration, observability, security, governance, integrations, evaluation, and platform engineering. Engineers joining the project will have an opportunity to influence key architectural and technical decisions and contribute to a new platform rather than maintaining an existing solution.
Requirements:
• 4+ years QA engineering for AI/ML or agent systems
• Tested LLM agent workflows (tool calling, multi-step reasoning)
• Security testing for authorization and authentication
• Performance benchmarking for cloud services
• Agentic workflow testing — agent tool discovery, tool invocation, multi-step agent workflows
• MCP protocol testing — tool list aggregation, tool call routing, streaming response handling
• Agent authorization testing — unauthorized tool access attempts, policy enforcement
