About AFS
Advanced Field Solutions is an established software company building field-service management products used by organisations across Ireland and the UK.
Our platforms contain approximately four million historical service records. We are now using this operational data to develop practical AI products, including voice agents, diagnostic assistants, intelligent reporting, knowledge retrieval, workflow automation and natural-language access to business data.
This is an opportunity to build AI systems around real products, customers and operational data—not purely experimental or academic projects.
The role
We are looking for an Applied AI Engineer with strong Python foundations and genuine hands‑on experience building AI or LLM-based systems.
The immediate focus is AI development rather than general frontend or traditional backend work. You will work closely with our existing AI engineer and product team to take AI features from an identified business problem through development, testing, deployment and ongoing improvement.

- Retrieval‑augmented generation using company and customer knowledge.
- Tool‑calling and agentic systems connected to APIs and databases.
- Natural‑language querying of structured operational data.
- Diagnostic assistants that learn from historical service cases.
- Automated onboarding, reporting and business‑process workflows.
- Evaluation systems for accuracy, faithfulness and reliability.
- Monitoring latency, token usage, cost and production failures.
- Python APIs and services supporting AI products.
- Deployment and operation of AI services in production.

Essential experience
- At least two years of substantial Python development experience.
- Hands‑on experience building an AI or LLM system used by real customers, employees or production users.
- Experience with LLM APIs, RAG, tool calling, agents or structured model outputs.
