Model Validation Senior Manager

Monzo is seeking a Model Validation Senior Manager to lead independent oversight of Generative AI models and use cases, with a particular focus on systems developed by its Operations teams. The role sits within the second-line Model Oversight team and can be based in London or Cardiff, or worked remotely within the UK, with occasional London meetings.

You’ll help the bank use AI responsibly by setting validation approaches, supporting colleagues who build models and ensuring that risks are identified and managed. The position combines technical review, relationship-building and leadership across model risk practices.

What you'll do:

• Develop and embed standards, methods and practical tools for validating Generative AI models and use cases.
• Lead independent reviews of new and changed operational models, and present clear findings to relevant committees.
• Work with model development and risk teams to strengthen governance, monitoring and risk controls.
• Check ongoing model performance and drive action plans where risks need to be reduced.
• Coach oversight colleagues and encourage consistent model risk practices across Monzo.

What they're looking for:

• Strong data science or machine learning experience and Python skills.
• Practical knowledge of Generative AI evaluation, architectures, tools and platform alignment.
• Experience assessing Gemini implementations and managing modelling work through its lifecycle.
• Clear communication, attention to detail and the ability to challenge constructively while building relationships.
• Coaching, standard-setting or banking model risk knowledge would be useful.

The role offers flexible working hours, with the expectation that you work enough to do the job well. Pay is £85,000–£105,000, plus performance-linked incentive awards. Monzo also provides a £1,000 annual learning budget for books, training and conferences.
