• Strong software engineering fundamentals in one or more of C#, Python, or TypeScript/JavaScript.
• Experience integrating with LLM provider APIs such as OpenAI, Anthropic Claude, or equivalent.
• Working knowledge of embedding models, vector databases, and semantic search.
• Familiarity with cloud infrastructure on Azure or equivalent, including deployment, storage, compute, and managed AI services.
• Experience with source control, Git, CI/CD pipelines, and test-driven development.
• Ability to evaluate and benchmark AI model output quality, cost, and latency.

Desirable:

• Experience with agent orchestration tools such as OpenClaw or Hermes.
• Knowledge of data privacy regulations and their implications for AI systems handling customer data.

Responsibilities:

• Architect and maintain the orchestration layer that coordinates AI agents to design, write, test, and deploy production code.
• Define guardrails, evaluation frameworks, and human-in-the-loop checkpoints that make agentic development safe and auditable.
• Write the majority of production code using AI coding tools, treating AI as a first-class collaborator.
• Continuously evaluate new agent frameworks, models, and tooling and recommend adoption where there is clear product or velocity benefit.
• Design and build LLM-powered features within our platform, including natural language interfaces, intelligent summarisation, and automated insight generation.
• Own prompt engineering, RAG pipeline design, and the retrieval architecture underpinning AI features.
• Integrate with external model providers and evaluate when to use third-party APIs versus fine-tuned or self-hosted models.
• Implement robust evaluation pipelines to measure output quality, latency, and cost across AI features.
• Design and maintain embedding pipelines, vector stores, and semantic search capabilities that power AI features.
