A bit about the job

As a Senior Principal Applied AI Engineer, you will hold accountability for the long-term technical vision, architectural integrity, and operational resilience of critical AI platforms and solutions.

You will act as the senior technical authority for applied AI engineering, ensuring that strategic technology decisions support business objectives, regulatory expectations, and customer outcomes.

You will work closely with senior leaders across Technology, Data, Risk, Security, and the wider business to shape investment priorities, influence enterprise strategy, and ensure the successful adoption of AI capabilities across Aviva.

Through your leadership, you will create the conditions for engineering teams to deliver high-quality, scalable, and trustworthy AI solutions with confidence.

You'll be responsible for :

• leading the architecture and delivery of multi-agent AI systems for high-value business use cases.
• defining engineering standards across orchestration architectures, context engineering, MCP integration, memory design, fine-tuning, evaluation frameworks and multimodal systems.
• building reusable AI capabilities including agent tools, MCP servers, skills and shared engineering assets.
• establishing quality, safety and governance standards for production AI systems.
• leading the shift to spec-driven development in the organisation.
• providing technical leadership, architecture reviews and mentoring.
• partnering with business, product and architecture teams to translate AI opportunities into scalable solutions.
• helping grow the Applied AI Engineering capability through hiring, coaching and community leadership.

Skills and experience we are looking for

• Extensive experience leading the strategy, architecture, delivery, and operation of complex applied AI, machine learning, or LLM-powered systems at enterprise scale, with accountability for business-critical outcomes.
• Recognised technical authority with a proven track record of setting technology direction, making high-impact architectural decisions, and influencing engineering standards across multiple teams, functions, or domains.
• Deep expertise in software engineering and Python, with the ability to drive engineering excellence, scalability, resilience, security, and operational maturity across large-scale AI platforms.
• Strong experience partnering with senior leaders and executive stakeholders, translating complex technical concepts into clear business outcomes, influencing investment decisions, and aligning diverse groups behind a shared vision.
• Proven ability to lead the safe and responsible adoption of AI in regulated environments, balancing innovation with governance, risk management, compliance, and customer trust

Why Aviva:

This is an opportunity to help build AI in a highly trusted environment, where customer outcomes, governance and responsible innovation matter.

You'll join a business with proven AI capability, significant digital reach, modern technology foundations and the ambition to scale AI across the organisation.
