About The Role

Branch is seeking a seasoned and technically deep Senior Director of Actuarial to lead the P&C actuarial function, with direct ownership of reserving, pricing, and predictive modeling. In this role, you will define and execute the actuarial strategy, ensure the integrity and soundness of loss reserves and pricing frameworks, and deliver the analytical insight that informs underwriting strategy, financial planning, and risk management.

This is a leadership role for a credentialed actuary who brings both technical authority and the ability to lead and develop a high-performing team. You are expected to own a complex, regulated domain with deep expertise, operate with a high degree of independence, and translate actuarial findings into clear recommendations for senior and executive stakeholders. This role is ideal for someone who can define the strategic direction for the actuarial function while staying close enough to the work to drive quality and solve hard problems in a fast-moving environment.

• Lead reserve adequacy reviews and communicate findings and recommendations to senior management, Finance, and external auditors; facilitate final determinations on reserve positions.
• Develop pricing methodology and rate adequacy positions across lines of business, ensuring frameworks are technically sound, current, and compliant with regulatory and internal standards.
• Direct financial and economic analyses that inform underwriting strategy, profitability assessments, and capital planning; make final recommendations on actuarial inputs to those processes.
• Establish, maintain, and improve actuarial policies, methodologies, and workflows that support accuracy, compliance, and scalability as the business grows.

• Lead, coach, and develop a team of actuarial professionals, including managing performance, supporting career growth, and building team capacity for current and future needs.
• Identify and implement opportunities to improve actuarial systems, tools, and processes to increase efficiency, transparency, and analytical quality.

• Typically 10+ years of progressive actuarial experience.
• Deep technical expertise in P&C actuarial methodologies, including loss development, pricing trend analysis, and predictive modeling techniques.
• Proven experience leading and developing actuarial teams, including managing individual contributors and developing team members for growth.
• Experience establishing or improving actuarial processes, controls, and team operating rhythms in a complex or scaling environment.
• Advanced proficiency in data extraction (e.g. Python, R) and analytical tools; familiarity with data science and modeling platforms (e.g. Akur8) is a plus.
• Effective communicator who can present technical conclusions clearly to senior leadership, regulators, and external stakeholders.
• Comfortable operating with a high degree of ownership and accountability in a fast-paced, high-growth environment.
