Corporate Actuarial Manager

Who are we?

Look at the latest headlines and you will see something Ki insures. Think space shuttles, world tours, wind farms, and even footballers’ legs.

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.

Ki is proudly the biggest global algorithmic insurance carrier. It is the fastest growing syndicate in the Lloyd’s of London market, and the first ever to make $100 m in profit in 3 years.

Ki’s teams have varied backgrounds and work together in an agile, cross‑functional way to build the very best experience for its customers. Ki has big ambitions but needs more excellent minds to challenge the status‑quo and help it reach new horizons.

You’ll be at the forefront of our corporate actuarial activity, guiding our business planning, performance monitoring, and strategic decision‑making across Ki’s underwriting portfolio. You’ll provide the high‑quality actuarial insight and forward‑looking analysis needed to enhance portfolio performance and sharpen our risk management.

You’ll be central to connecting our actuarial, underwriting, risk, and finance teams, ensuring we make consistent and well‑informed decisions together. You’ll lead the development of innovative tools and frameworks that support our portfolio optimisation and business planning. You’ll also be a key part of our drive for continuous improvement of Ki’s actuarial capabilities, systems, and processes to help us achieve our strategic goals.
