Who We Are

Independent for over 75 years, Milliman delivers market-leading services and solutions to clients worldwide. Today, we are helping companies take on some of the world’s most critical and complex issues, including retirement funding and healthcare financing, risk management and regulatory compliance, data analytics and business transformation.

Milliman invests in skills training and career development, and gives all employees access to a variety of learning and mentoring opportunities. Our growing number of Milliman Employee Resource Groups (ERG’s) are employee-led communities that influence policy decisions, develop future leaders, and amplify the voices of their constituents. We encourage our employees to give back to their varied professions, including leadership in professional organizations.

The Atlantic Region Property and Casualty (P&C) practice, with locations in Boston MA and Burlington VT, provides actuarial consulting services on a range of projects across the insurance, reinsurance, insurance-linked securities (ILS) and alternative-risk markets. We work with a diverse set of clients including self-insured corporations, commercial insurance companies, governmental agencies, risk pools, and financial investors. Using a variety of Milliman products and practice-built tools, we look to establish and develop the cutting edge of actuarial practice in each of our professional niches, and provide our clients with trusted partnership and advice to advance the financial well-being of people everywhere.

The team is a focused and tight-knit group, working together across multiple locations. Team members work on a range of client projects of various sizes, and we employ a highly integrated project structure that encourages interaction across all members of the team, from Analysts to the Principals who serve as client leads. While most of our team’s time is spent working with members of the practice, we also have assignments that are completed in partnership with other Milliman offices around the world.

We believe that the actuarial skillset has important applications across both our traditional actuarial work and our work in developing market areas, and are committed to developing a pipeline of actuarial talent and future leaders of the firm through exam support and interaction with senior colleagues.

What You Will Do

On a day-to-day basis, the Actuarial Intern will work closely with project team members to execute key analyses for ongoing projects. They will be given opportunity to produce high-quality analytical work while also showing professionalism and strong communication skills when interacting with colleagues, up to and including senior Principals of the firm. Much of the Intern’s work will be done in Excel, but supplemental programming, statistical, and database skills are highly valued and will open additional opportunities for impactful client assignments and advancement.

The Atlantic Region P&C practice welcomes interns each summer, but may also have work during the fall and/or spring semester(s), depending on availability. When applying, you will be asked to estimate your upcoming availability for work.
