Senior AI Integration Engineer in London

At MONY Group, we’ve spent the last 30 years making it easier for people to save on their household bills, growing beyond comparison to support multiple areas of daily spending. As technology evolves, then so do we, looking at ways that we can improve our products and services to help our users save more than ever before. Our work is fast-paced, collaborative, and constantly evolving – just like our teams that power it.

We are looking for a talented AI Integration Engineer to join our growing team focused on building intelligent, customer-facing AI agents. In this role, you’ll leverage cutting-edge technologies, from large language models to multi-agent orchestration frameworks, to create high-impact AI solutions that directly interact with users. You'll also embrace the power of AI-assisted development to boost your productivity and code quality.

AI at MONY Group

Our strategy covers three core areas: how AI enhances the way we build and deliver products, how AI is embedded in existing products to enrich customer journeys with insight and value, and how services are built from the ground up for generative AI platforms, enabling holistic, conversational problem-solving. This role is sat in a team building our AI-native journeys. Consumer behaviour is rapidly shifting, and we're looking at how we reach customers in new channels and tackle problems in ground-breaking ways. Our work is underpinned in two ways: how we are enhancing what we offer today and what we’ll offer tomorrow.

What will you be doing in the role?

• Design, develop, and deploy intelligent AI agents using frameworks like Vercel AI SDK, LangChain, or AutoGen.
• Integrate and optimize large language models (LLMs) through prompt engineering, chaining, and memory/context handling.
• Enable agent-to-agent collaboration and reasoning workflows to support advanced customer interactions.
• Develop scalable backend systems using Node.js and TypeScript.
• Use GitHub Copilot and similar AI-powered development tools to accelerate coding, testing, and debugging workflows.
• Build and maintain CI/CD pipelines to ensure smooth deployment and continuous improvement.
• Work with AWS infrastructure (Lambda, ECS, S3, API Gateway, etc.) for scalable and secure deployment.
• Collaborate closely with product managers and designers to deliver user-focused AI experiences.

What we're looking for:

• Strong experience with LLMs, prompt design, and agent frameworks.
• Proficient in TypeScript, Node.js, and modern backend architecture.
• Comfortable with AWS services and infrastructure-as-code.
• Familiar with CI/CD tools and DevOps best practices.
• Experience using AI tools like GitHub Copilot to enhance software development productivity.

Nice to Have:

• Master’s or Ph.D. in Computer Science, Artificial Intelligence, Machine Learning, or a related field.
• Experience developing multi-agent systems or autonomous reasoning workflows.
• Familiarity with front-end tools like React or Next.js for end-to-end integration.
• Understanding of responsible AI principles, including model safety and ethical considerations.
