The Opportunity

An exciting opportunity has arisen for a Senior AI/ML Engineer to join a highly innovative team operating within a large global organisation. Working in a startup-style environment, you’ll play a critical role in shaping and delivering the next generation of Generative AI products.

This team is focused on building AI-powered MVPs, validating product-market fit, and creating scalable solutions that can be adopted across a broader enterprise landscape. They’re looking for an experienced engineer who can bring technical leadership, engineering discipline, and a pragmatic approach to turning ambitious AI concepts into reliable, production-ready solutions.

The Role

This is a hands-on contract position where you’ll provide technical oversight and help establish best practices across AI engineering, MLOps, deployment, and productionisation.

You’ll be expected to quickly assess existing approaches, improve technical foundations, and help ensure the team is building solutions that are secure, scalable, and maintainable.

Key Responsibilities

• Review and validate AI solution architectures and engineering approaches.
• Bring engineering rigour and governance to AI product development.
• Establish coding standards, testing practices, and development workflows.
• Productionise machine learning and Generative AI solutions.
• Develop and maintain ML pipelines and deployment frameworks.
• Implement monitoring, logging, observability, and model performance tracking.
• Conduct LLM security assessments, including prompt injection testing and mitigation.
• Collaborate closely with Data Scientists, Engineers, Product stakeholders, and external partners.
• Support the team in moving from experimentation to robust, scalable delivery.
• Provide hands-on technical guidance while remaining actively involved in development.

Technology Stack

Essential Experience

• Expert-level Python development
• Azure cloud platform
• Databricks
• MLflow
• Containerised environments (Docker or similar)
• Machine learning pipeline development
• CI/CD and deployment automation
• Software engineering best practices and automated testing
• Jupyter Notebooks

AI & Machine Learning Expertise

• Generative AI applications
• Large Language Models (LLMs)
• Retrieval-Augmented Generation (RAG)
• Vector databases
• NLP and content generation platforms
• Prompt engineering
• AI application architecture
• Model monitoring and governance
• LLM security and evaluation

Desirable Experience

• Startup or scale-up environments
• Conversational AI and chatbot development
• Healthcare, life sciences, or regulated industry experience
• Responsible AI and AI governance initiatives
• Product-focused AI engineering

Candidate Profile

We’re looking for a practical, delivery-focused engineer who is comfortable operating in ambiguous and fast-moving environments.

You’ll likely have:

• A strong software engineering background combined with modern AI/ML expertise.
• Experience building and deploying AI products in production environments.
• A systems-thinking approach to architecture and technical decision-making.
• Strong stakeholder communication and collaboration skills.
• The confidence to challenge assumptions and improve technical direction.
• A product-oriented mindset, understanding how technology delivers business value.
• A passion for creating scalable, maintainable AI solutions rather than simply building prototypes.

This role would suit someone who enjoys bringing structure and clarity to complex technical challenges and helping teams deliver high-quality AI products.

Team Structure

You will work alongside:

• Product Manager
• Data Scientists
• Python Engineers
• AI Engineers
• Solution Architect
• Front-End Developers
• External Delivery Partners

This is a senior individual contributor role with significant technical influence but no direct line management responsibilities.

Why Apply?

• Join a high-impact Generative AI programme.
• Work on cutting-edge AI products and platforms.
• Influence technical architecture and engineering standards.
• Enjoy startup-style autonomy with enterprise-scale backing.
• Make a visible impact from day one.
• Collaborate with a highly skilled multidisciplinary team.
