About the Company
Our client is an established insurance business based in Dublin, investing seriously in agentic AI alongside a mature conventional machine learning estate. The programme is delivered in partnership with one of the world's largest IT services and consulting providers, bringing global AI expertise and tooling to the work. It's a rare chance to shape a modern agent platform inside a regulated enterprise, where engineering decisions carry real weight.
The Role
This is the senior engineering seat on the programme. You'll own the architecture of the agent estate, from how agents and conventional ML models are built and deployed to how they're observed and kept reliable in production. You'll pair closely with the data science leadership on shared priorities and mentor the Senior Machine Learning Engineer. It suits a principal or staff engineer who still writes code, has carried production systems through real incidents, and is just as comfortable setting long term technical direction.
Key Responsibilities
- Own the end to end architecture of the agent estate, covering build, deployment, monitoring and reliability
- Set the standards and reusable patterns for CI/CD, environment management and release processes across ML models and agentic services
- Design how the platform uses MCP servers and A2A agent to agent communication, so agents can be composed, discovered and orchestrated reliably
- Establish production observability and evaluation practices for LLM based and conventional ML systems, including monitoring, alerting, drift detection and rollback
- Lead the integration of new agentic components with legacy services and existing data sources
- Act as the senior technical authority on Azure or AWS AI infrastructure, including evaluation of Azure AI Foundry
- Mentor the Senior Machine Learning Engineer and set technical direction across the wider engineering function
- Represent engineering feasibility, cost and risk in architectural decisions made jointly with data science leadership
- Serve as the escalation point when a production issue needs deep infrastructure expertise
What You'll Need
Essential:
- 8+ years in machine learning or platform engineering, with hands on ownership of production systems
- Proven experience building AI infrastructure at scale on Azure (strongly preferred) or AWS
- Experience running conventional ML models and agentic or LLM systems side by side in the same estate
- A track record of greenfield delivery integrated with legacy services and data sources
- Python at senior or architect level
- Docker or Podman, Terraform, and ownership of CI/CD pipeline design in an ML context
- SQL and database management
- MCP server development and A2A (Agent2Agent protocol), or deep agent to agent and tool orchestration experience you can map onto them quickly
- MLOps and LLMOps, including production observability and evaluation
- Experience with at least one agent framework or SDK
- Eligible to work in Ireland and able to be in the Dublin office around 2 days a week
Desirable / Nice to Have:
- Azure AI Foundry experience
- RAG systems and vector stores such as pgvector or Pinecone
- ETL and DAG orchestration tooling, or serverless architectures
Why Apply?
- Extremely competitive day rate
- 6 month contract with extension possible
- Hybrid working, around 2 days a week on site in Dublin, with NI commuters welcome
- Set the technical direction for a greenfield agentic platform
- Put the newest agent standards, MCP and A2A, to work in a real production estate
- Genuine influence, with an equal voice alongside data science leadership on architecture
