Job description

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.

Where you come in?

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.

What you will be doing

• Lead the development, validation, and ongoing monitoring of business plans and portfolio performance, including setting and challenging key actuarial assumptions (e.g. IEULR) and ensuring alignment with reserving and risk views.
• Partner with Portfolio Management, Underwriting, Claims and Finance to provide clear, actionable insight on portfolio profitability, performance drivers, and strategic direction.
• Drive enhanced performance management through high‑quality analysis, targeted reporting, and effective communication of insights, incorporating reserving outputs, market developments, and forward‑looking indicators.
• Deliver deep‑diving and forward‑looking analysis to understand and improve performance, including macroeconomic factors (e.g. inflation, climate) and emerging risks, supporting underwriting and portfolio optimisation decisions.
• Collaborate across actuarial, risk, and algorithmic underwriting teams to strengthen analytics, tools, and data‑driven capabilities, including development of new techniques and approaches to improve underwriting performance.
• Build and maintain strong stakeholder relationships, providing effective challenge and influence at senior levels to support robust and commercially sound decision‑making.
• Lead the development and continuous improvement of actuarial tools, frameworks, and processes, including areas such as inflation assumptions, benchmarking, and performance monitoring capabilities.
• Ensure robust governance, documentation, audit trails, and compliance with actuarial, regulatory, and internal standards across all areas of responsibility.
• Support the ongoing development of actuarial systems, data, and analytics capabilities, ensuring data quality and fitness for purpose.
• Contribute to the wider actuarial function through collaboration, innovation, knowledge sharing, and continuous improvement initiatives.
• Maintain a strong understanding of the end‑to‑end business and proactively apply emerging trends, techniques, and insights to enhance actuarial output and business impact.
• Represent actuarial in relevant governance forums, providing insight, challenge, and informed judgement.
• Lead, develop, and effectively manage direct reports, ensuring high‑quality delivery, appropriate prioritisation, and individual development.

Qualifications and experience

• Qualified Actuary (FIA, FFA or equivalent) with strong general insurance market experience, ideally within Lloyd’s or company markets.
• Strong understanding of actuarial disciplines including pricing, reserving, and business planning, and how these interact across a portfolio.
• Experience leading and developing teams, with the ability to prioritise work and manage competing demands.
• Strong commercial acumen with the ability to translate complex actuarial outputs into clear business insights.
• Advanced analytical and technical skills, including proficiency in Excel and experience with programming languages such as Python, R, or SQL.
• Strong communication and stakeholder management skills, with the ability to influence senior stakeholders effectively.
• Innovative mindset with the ability to identify opportunities for improvement and implement change.
• Strong understanding of actuarial governance, regulatory requirements, and professional standards.
