**ACTUARIAL INTERN**

Join Mercer as a summer intern with our actuarial team and experience working for a global company shaping the future of Health, Wealth, and Career consulting.

For many companies, their pensions arrangements can represent a significant financial risk. Our actuarial team provides comprehensive advice to trustees and corporate sponsors of defined benefit pension schemes in areas such as scheme funding, individual benefits, risk management and more.

As trusted advisors, our main goal is to communicate complex analysis in simple terms for our clients to make well-informed decisions on their pensions issues. During your internship you will support analysts and consultants with this work while gaining valuable knowledge about financial markets and the pensions industry.
