Ki’s mission is simple. Digitally disrupt and revolutionise a 335-year-old market. Working with Google and UCL, Ki has created a platform that uses algorithms, machine learning and large language models to give insurance brokers quotes in seconds, rather than days.

Where you come in?

The Head of Reserving is a senior leadership role within the Ki Actuarial Leadership Team and a visible, influential voice across the Ki - accountable for owning and continuously elevating Ki’s reserving capabilities and translating technical rigour into genuine commercial insight. The best reserve estimates matter, but so does what you do with them: this role is expected to be a genuine business partner, bringing the reserving lens on underwriting performance and long-term profitability - not just back-office sign-off. 

The role is highly technical, leading the Actuarial Reserving and Regulatory teams, overseeing the full quarterly reserving cycle alongside related regulatory and statutory processes including IFRS 17 and Solvency II Technical Provisions. It sets and owns the Reserving Policy, maintains robust governance, and ensures all outputs meet the highest professional and regulatory standards - with clear audit trails, well-justified assumptions, and tight controls across the full reserving and regulatory domain. This is a leadership role, which developing and managing an experienced team, as well as a variety of internal and external stakeholders, is core. 

But equally important is the ability to think creatively, move quickly, and influence decisively. The ideal candidate is a self-starter and agile thinker: technically excellent, commercially minded, a natural project and stakeholder manager, and a problem-solver who thrives in complexity. In a business that is still building and evolving, this person will be energised by the opportunity to define what ‘best in class’ looks like - and then build it.
