AI Engineering LEAD – design & build End-To-End AI Solutions Leading global Wellness & Heal

This is an exceptional opportunity for an ARTIFICIAL INTELLIGENCE ENGINEERING LEAD (AI Engineering lead) - with advanced Quantitative Analytical skills - to design, build, and run end-to-end AI Solutions for the world’s leading Wellness / Health Tech Business.

Based in LONDON, this AI ENGINEERING LEAD role offers a salary of £120K – £130K

This globally recognised brand is a Health Tech & Wellness company that blends smart technology and world-class facilities into transformative wellbeing experiences. They are a next‑generation Health Tech brand using intelligent tools, digital platforms, and science‑backed training environments to optimise how people move, recover, and live.

Their digital innovation journey is in full‑swing, and now at the point where AI INNOVATION will result in an even better experience for their 1 million consumers.

The company is scaling AI safely, responsibly, and at speed across South Africa, the UK, Italy, Australia, Singapore, Thailand, and Qatar. They are building a world‑class team of AI Engineers who can design, build, and run AI solutions that millions of consumers use every day. This role is your chance to lead that journey.

As Lead AI Engineer, you’ll own entire problem spaces, lead mission‑critical AI initiatives, and shape how AI is delivered across the organisation. You’ll sit at the intersection of software engineering, data engineering, machine learning, and quantitative analytics, working end‑to‑end from problem framing through to deployment, monitoring, and scaling across multiple countries.

This is a hands‑on technical leadership role: you’ll build, mentor, architect, influence, and set the bar for how AI should be done in this global consumer business.

• You’ll be the technical lead for areas like CRM & personalisation, operations optimisation, or digital coaching - defining roadmaps, making architectural decisions, and guiding teams through discovery, experimentation, and delivery.

• From prototypes to scaled deployments, you’ll design and ship systems that power real‑world experiences: personalised journeys, churn prediction, lead scoring, RAG‑based knowledge assistants, energy optimisation, operational AI tools, and more.

• Analyse and prepare data for AI use‑cases: consumer behaviour, CRM interactions, digital journeys, operations, marketing and sales, energy consumption, etc.;
  Build and evaluate models using appropriate techniques, including classical machine learning, LLM and generative AI; design and implement prediction models for use cases like churn, propensity, next best action, lead scoring, lifetime value. Set technical direction for modelling approaches. Support the creation of synthetic personas and segmentation using a mix of data‑driven and generative techniques. Develop and test marketing mix models and other measurement frameworks to understand and optimise marketing spend.
  
  Define evaluation strategy and acceptance criteria for your use‑cases, guide others in doing the same, and ensure that evaluation practices are consistent and repeatable across the team.

• You’ll work with Marketing, Digital, Operations, Finance, and Legal to turn ambiguous problems into structured AI opportunities; define hypotheses and success metrics; run rapid A/B tests and pilots; align multiple teams around a single plan; communicate model limits, trade‑offs, risks, and value in plain language.

• You’ll architect and build APIs, services, pipelines, integrations, guardrails, and monitoring frameworks - ensuring that AI is safe, reliable, scalable, cost‑efficient, and compliant.

• You’ll mentor engineers and data scientists, review critical designs, coordinate external partners, and ensure solutions are production‑ready before scaling globally.

• You’ll contribute patterns, templates, starter kits, documentation, playbooks, internal demos, training sessions, and hiring - raising the bar for the entire group.
