• Independently review and validate opposing-party valuations, reserving methods, model implementations, and assumption choices.
• Ensure reproducibility and maintain complete audit trails and documentation of models and analyses used in expert opinions.
• Collaborate closely with outside counsel and internal subject-matter experts to align technical work with legal strategy and discovery requirements.
• Advise clients on settlement drivers, regulatory exposures, capital impacts, and reinsurance/retrocession implications.
• Mentor and supervise actuarial staff contributing to expert engagements; maintain high standards of quality control and peer review.
• Keep abreast of actuarial standards of practice, relevant legal precedents, and regulatory developments affecting insurance/reinsurance disputes.

Qualifications

• Bachelor’s degree in Actuarial Science, Mathematics, Statistics, Finance, or a related quantitative field.
• ASA or FSA (or equivalent) required.
• Minimum 10+ years of actuarial experience in life insurance, annuities, or reinsurance with strong background in liability valuation, reserving, and pricing.

• Demonstrated experience with variable annuities, equity guarantees, or other complex life/annuity products is highly desirable.
• Proficiency in reserving, valuation frameworks (statutory, GAAP/IFRS), experience studies, and stochastic modeling.
• Strong model development, validation, and documentation skills; familiarity with actuarial platforms (e.g., Prophet, GGY) is advantageous.
• Ability to produce reproducible analyses and maintain full audit trails suitable for legal scrutiny.
• Experience preparing expert reports and working with outside counsel; prior deposition/testimony experience highly desirable.
• Comfort translating complex technical material into clear, defensible findings for legal audiences.
• Excellent written and verbal communication skills; ability to present to non-technical audiences (judges, juries, executives).
