Senior AI Specialist

About the Role & Opportunity

Cathcart Technology is partnering with a well-established organisation in Thailand that is growing its AI capability and looking for a Senior AI Specialist to turn business challenges into working AI solutions. Sitting within a central AI and data team, this role works closely with business users to identify where AI can create real value across sales and customer-facing operations. You will take ideas from first conversation to working Proof of Concept, then hand them over to engineers for production. This is a hands-on, business-facing role for someone who enjoys building and solving business problems.

Key responsibilities

• Running discovery sessions with business users and Product Owners to identify and define high-value AI use cases
• Assessing each use case for data readiness, risk, effort and expected value, including recognising when a non-AI solution is the better choice
• Building rapid Proofs of Concept using LLMs, RAG, chatbots and agentic workflows to validate ideas with real users and data
• Developing evaluation methods and quality benchmarks covering accuracy, groundedness, safety, latency and cost
• Writing clear, testable specifications and acceptance criteria as the handover to AI Engineers
• Recommending model and architecture options, balancing performance, cost, security and vendor lock-in
• Embedding security, privacy and responsible-AI practices into every solution
• Tracking token and API costs from POC onward and recommending optimisations
• Creating reusable assets such as prompt templates, evaluation datasets and playbooks to grow the team's AI capability

Key Qualifications

• Solid hands-on experience building GenAI and LLM applications, with a track record of POCs delivered with business users
• Strong Python skills for prototyping, data handling and API integration
• Practical experience with RAG (embeddings, vector databases, retrieval tuning) and frameworks such as LangChain or LangGraph
• Experience building chatbots and AI agents, including tool or function calling and human-in-the-loop controls
• Ability to design evaluations for LLM systems and use the results to make go/no-go decisions
• Confident communicating AI options and trade-offs to non-technical stakeholders
• Understanding of AI security and responsible AI, including prompt injection, data privacy and PII handling
• Experience with NLP, voice or speech AI is a strong advantage
• Exposure to cloud AI platforms (GCP, AWS or Azure), MCP or coding agents such as Claude Code or Cursor is a plus

If you are an experienced AI professional looking to shape how a growing business applies Generative AI in practice, we would be glad to hear from you.
