About AFS Labs
AFS Labs is the new innovation division of Advanced Field Solutions, a leading field service management software provider operating across Ireland, the UK, Poland, and Spain.
We are building next-generation AI tools for field service engineers — including multi-engine AI querying, automated reporting, device identification, and intelligent work-planning.
Our customers will rely on these tools in real-world jobs, so accuracy and trust are essential.
Your job is to make sure the AI outputs are correct, consistent, and reliable.
Role overview
We are seeking a highly detail-oriented AI QA & Product Validation Tester to join our AFS Labs team in Spain.

You will:
* Test and validate AI-generated answers
* Compare outputs across multiple AI engines (GPT-5, Claude, Gemini, etc.)
* Build confidence scoring frameworks
* Document edge cases, safety risks, and required follow-ups
* Work closely with developers to ensure reliable, predictable AI behaviour
Essential skills:
* Sharp analytical and critical-thinking ability
* Very strong written English
* Exceptional attention to detail
* Natural scepticism toward AI output
* Ability to think like a customer
* Strong communicator
* Able to work independently in a small team
What we offer:
* Market-level competitive compensation
* A high-impact role in a well-funded, long-established company
* Direct involvement in building next-generation AI tools
* A focused, calm work environment in southern Spain
* Opportunities to shape the direction of AFS Labs
