Senior Backend/Platform Engineer

Barden is delighted to partner with a growing tech company in Cork in their search for a Senior Platform Engineer.

This person will have strong backend engineering experience and will be responsible for building and scaling the core backend services that power their engineering teams. With continued expansion, the company is now investing heavily in AI-powered platform capabilities.

You will work directly with the Head of Platform Engineering, focused on building the internal services, tools, and frameworks that power the entire engineering organisation; not end-user product features or infrastructure maintenance.

You’ll help shape core platform areas such as:

• Auth & Identity
• Messaging Infrastructure
• Shared Libraries & SDKs
• Agentic / AI tooling & workflows
• Developer Experience tooling
• Design system components
• Select product-enabling platform features

What they’re looking for:

• Strong experience in Python or Node.js/TypeScript, plus C#
• Background in building cloud-native distributed systems
• Hands-on experience with MCP / agentic AI platforms, such as LangChain, LangGraph, LangSmith, Azure AI Foundry, Amazon Bedrock, or CrewAI (production experience preferred)
• Experience with Docker and Kubernetes (or Azure Container Apps) in production environments
• Proven track record of building platforms, services, or internal tools used across multiple teams

Details:

• Hybrid role: 3 days/week in Cork city office
• Salary: open and talent-led (flexible based on experience)
