Director, Data Science & AI Engineering
Overview
This role leads the organisation’s enterprise data-science, analytics and AI-engineering strategy end to end. It is responsible for building and running a multidisciplinary team of data scientists, data analysts and MLOps/AI engineers who deliver production-grade AI solutions supporting the business’s legal and operational work.
Core responsibilities span the design, build and optimisation of LLM-powered applications, retrieval-augmented generation (RAG) systems, AI agents, custom models, and the analytics/BI platforms that give leadership visibility into matters, finances and operations.
It is a hands-on, strategic leadership role in a fast-moving AI environment: the Director sets up scalable architecture, governance, evaluation standards, security practices and operating frameworks appropriate to a highly regulated professional-services business, working closely with Knowledge Management & Innovation and other stakeholders to turn legal and operational needs into practical AI solutions.
Key responsibilities
Leadership
- Design the operating model, team structure, delivery process and metrics for the Data Science & AI Engineering function.
- Hire, develop and lead a multidisciplinary team of data scientists, analysts and MLOps/AI engineers, setting strong technical and cultural standards.
- Own day-to-day operations — planning, prioritisation, delivery, performance management, mentoring and development.
- Build a collaborative, business-focused culture centred on practical AI and analytics outcomes.
Building & Running Internal AI Platforms
- Design, build and deploy internal AI applications on approved LLMs, with an eye on scale, evaluation, observability and cost.
- Lead development of the organisation’s RAG capability — ingestion, embeddings, vector/hybrid search, re-ranking and citation-backed responses across firm knowledge and matter data.
- Oversee integrations between AI tools and core business systems (document management, matter management, finance, timekeeping, knowledge management), using secure, governed frameworks such as MCP.
- Build AI-driven workflows and agent-based tools for legal/business processes, with proper governance, controls, traceability and human oversight.
- Direct model development, fine-tuning, evaluation and optimisation using proprietary data, in line with confidentiality, privilege, IP and security requirements.
- Lead analytics and reporting — data modelling, warehouse/lakehouse strategy, dashboards and BI tools giving leadership insight into operations, finance, staffing and AI usage.
MLOps, Engineering Excellence & Governance
- Set engineering and operational standards: source control, CI/CD, infrastructure-as-code, observability, environment management, evaluation and production support.
- Build and maintain MLOps/LLMOps capability: prompt/model versioning, automated testing, monitoring, drift detection, latency/cost tracking, incident management.
- Work with Information Security, IT, Privacy, Risk and General Counsel to ensure AI solutions meet confidentiality, privilege, client, data-governance and regulatory requirements.
- Support the organisation’s AI-governance framework — acceptable-use standards, vendor/model evaluation, testing and risk management.
- Assess build-vs-buy options, using commercial platforms where sensible and custom builds where they offer a strategic edge.
Cross-Firm Collaboration
- Align AI initiatives with Knowledge Management & Innovation priorities, business needs and adoption strategy.
- Partner with lawyers, practice groups and business stakeholders across the solution lifecycle.
- Communicate technical concepts and trade-offs clearly to business and legal audiences.
- Represent the organisation with vendors, clients, industry groups and the wider legal-AI community.
What we're looking for
- Bachelor’s degree in computer science, AI, machine learning, statistics, data science or a related quantitative field (or equivalent experience); advanced degree a plus.
- 10+ years in data science, machine learning or AI engineering, including proven leadership of high-performing technical teams.
- Track record shipping and supporting production AI/ML solutions — LLM applications, RAG systems, agent-based workflows.
- Strong technical grounding to evaluate architecture, engineering approaches and model performance.
- Deep knowledge of modern AI: foundation models, embeddings, vector databases, hybrid search, RAG, agent frameworks, MCP, prompt engineering, evaluation, fine-tuning and scalability.
- Experience setting up MLOps/LLMOps practice — cloud infrastructure, deployment automation, monitoring, security, governance.
- Demonstrated experience leading enterprise analytics/BI work, including executive dashboards.
- Strong leadership, organisational and problem-solving skills in fast-moving, collaborative settings.
- Excellent written/verbal communication, able to explain technical concepts and AI risk to non-technical stakeholders.
- Sound judgement on AI governance, privacy, security, confidentiality and ethics in regulated environments.
Also nice to have
- Experience in legal, professional-services, financial-services or another regulated, document-heavy industry; legal background a plus.
- Familiarity with legal-tech and enterprise data platforms (document management, matter/timekeeping systems, knowledge-management platforms, eDiscovery, litigation support).
- Hands-on experience with major AI platforms/tooling from leading providers, including familiarity with legal-specific AI tools.
- Active participation in the AI/ML community via publications, speaking engagements or open-source contributions.
