Tokyo Morgan McKinley

Company Overview

Our client is a global insurance and reinsurance broker with a strong footprint in Japan and an international operating model. The Japan business works closely with regional and global teams to support Japanese clients, combining local market understanding with cross-border delivery capability.

About the Role

This is a Junior Actuary position within a small Life actuarial team. You'll support reinsurance-related actuarial work (analytics, modelling support, and client materials), gaining hands-on exposure while working alongside experienced actuaries. The role is suitable for someone early in their actuarial/quantitative career, including those still in training.

Key Responsibilities

  • Support actuarial analysis for life reinsurance work, including basic modelling, assumption setting support, and output validation.
  • Assist with experience studies, data checks, reconciliations, and preparation of technical summaries.
  • Prepare Japanese client-facing reports and presentation materials with clear, accurate messaging.
  • Coordinate deliverables with internal stakeholders and global support teams to meet timelines and quality standards.
  • Maintain and improve templates/spreadsheets and contribute to process improvements to reduce operational risk.

Who We're Looking For

  • Early-career candidate (typically 0-3 years experience) from actuarial, insurance analytics, underwriting support, risk, finance, or another quantitative function.
  • Native-level Japanese is essential due to Japanese client communication and deliverables.
  • Strong numerical accuracy, logical thinking, and solid Excel capability (structured modelling, checks, clean outputs).
  • Actuarial exam progress or clear interest in pursuing actuarial development is a plus, but registration is not required for this junior seat.
  • English can be flexible if there is motivation and potential to improve in an international environment.

Why Apply

You'll join a business that is actively expanding and investing in Japan, with a small team environment where your work is visible and you can develop quickly. The role offers exposure to reinsurance broking and international stakeholders, plus flexibility through hybrid working and a modern office set-up, making it a strong platform for building marketable actuarial skills and long-term career progression.
