Back End Engineer (AI Platforms)

The Group AI Platform team sits within CTO Platforms, part of HSBC’s Chief Technology Office (CTO). We build shared AI foundations that enable teams across the Bank to deliver AI solutions faster, more safely and at scale.

Our platform provides a “paved road” for AI delivery, bringing together seamless access to AI models and infrastructure, a consistent Agent HUB to build, deploy and manage production-ready AI agents, reusable AI capabilities (such as knowledge management and document intelligence), and built-in controls including guardrails, evaluation and monitoring to support responsible adoption.

You’ll design, develop, test, deploy and support production-grade services covering agent execution, workflow orchestration, memory, context, MCP integrations, policy enforcement and platform APIs.

• MCP.
• RAG.
• Tool or function calling.
• Prompt and workflow management.
• Experience with Redis, PostgreSQL, Temporal, Pub/Sub or BigQuery is advantageous.
