• Translate business requirements, model enhancements, and analytical requests into maintainable, well-documented solutions.
• Partner with actuarial subject matter experts to support model validation, testing, and production readiness.
• Promote sound development standards, testing frameworks, documentation, and modeling best practices.
• Over time, take on broader responsibilities within Dividend Analytics, extending beyond the modeling platform into the team's core analytical and dividend-setting work, including assumption development, regulatory testing, and dividend liability analysis.

The Minimum Qualifications

• Bachelor's degree in actuarial science, mathematics, statistics, data science, computer science, engineering, or a related quantitative or technical field.
• ASA designation.
• 5+ years of actuarial experience within insurance, financial services, or a related quantitative field.

• Experience developing, maintaining, validating, or enhancing actuarial, financial, or other complex quantitative models.
• Demonstrated ability to translate business requirements into maintainable solutions while independently managing multiple priorities.

The Ideal Qualifications

• FSA designation.
• Experience with the design, pricing, modeling, or inforce management of participating life insurance products.
• Experience modernizing or converting legacy actuarial models into modern platforms.
• Understanding of model controls, governance, and risk management, including the ability to implement model development and management best practices.
• Strong collaboration and communication skills, with the ability to work across technical and non-technical audiences and navigate ambiguity.
