• Design, build, fine‑tune, and optimise LLM‑powered solutions, including custom models and retrieval‑augmented generation (RAG) frameworks.

• Architect and develop a scalable Hollis Copilot integrated with Microsoft 365, Dynamics 365 Document Management, and internal datasets.

• Build conversational AI agents with self‑training capabilities and automated reinforcement loops using property and consultancy data.

Data Engineering & AI Training Pipelines

• Collaborate with our in‑house data team to engineer robust pipelines that ingest, cleanse, classify, and index structured and unstructured data.

• Implement secure embeddings, vector stores, and knowledge graphs to support intelligent contextual search.

• Develop automated feedback and telemetry loops to enable continuous model improvement.

Microsoft Copilot & Cloud Integration

• Architect and deploy AI workloads on Microsoft Azure, including Azure OpenAI, Cognitive Search, Fabric, and Copilot extensions.

• Integrate AI capabilities into Microsoft Teams, SharePoint, Power Platform, Dynamics 365, and custom web applications.

• Develop plugins and extensions that enhance Microsoft Copilot with Hollis‑specific functionality.

Solution Design & Architecture

• Partner with the CTO, COO, and Innovation teams to translate business challenges into AI‑enabled solutions.

• Produce architectural designs, prototypes, proof‑of‑concepts, and technical documentation.

• Ensure all solutions meet high standards of security, professional compliance (including RICS and GDPR), and responsible AI governance.

Innovation & Delivery

• Lead the technical delivery of AI pilots and full‑scale deployments alongside the transformation team.

• Work closely with service heads, surveyors, product owners, and data teams to identify high‑impact AI use cases.

• Contribute to Hollis’ long‑term AI and digital innovation roadmap, including bespoke AI agents that automate and optimise business processes.

Essential Skills & Experience

• Expert knowledge of large language models, prompt engineering, fine‑tuning, and RAG systems.

• Strong hands‑on experience with Azure OpenAI, Azure Cognitive Search, Azure Machine Learning, and related services.

• Experience building Copilot extensions, Copilot Studio solutions, or custom copilots.

• Proficiency in Python, C#, or similar languages for AI integration and development.

• Experience with vector databases, embeddings pipelines, and similarity search.

• Strong understanding of Microsoft 365 architecture, data governance, and secure enterprise AI patterns.

• Experience with modern software engineering practices, including APIs, CI/CD pipelines, and containerisation (Docker, Kubernetes).

Desirable Experience

• Familiarity with property or real‑estate data, or AI applications in asset‑rich industries.

• Experience with knowledge graph technologies.

• Exposure to Microsoft Fabric or data lake architectures.

• Background in machine learning research or applied ML within enterprise environments.

Key Competencies

• A strong innovation mindset with the ability to turn ideas into practical, scalable solutions.

• Excellent communication skills, with the confidence to work across technical and non‑technical stakeholders.

• A problem‑solving approach focused on efficiency, scalability, and measurable business impact.

• Ability to work autonomously in a fast‑moving, evolving environment.

• A clear commitment to responsible AI, ethics, and compliance.
