Full job description

Definity is the parent company to some of Canada’s most long-standing and innovative insurance brands, including Economical Insurance, Sonnet Insurance, Family Insurance Solutions, and Petline Insurance. Our ambition is to be one of Canada’s leading and most innovative property and casualty insurers. We can’t do that without our people, so we embrace and encourage a culture that’s collaborative, ambitious, rewarding, and empowering.

We offer a flexible, hybrid work experience where employees work from the office and virtually depending on the type of work they are doing and who they are working with. Bring your true self and be a part of our journey. It’s better here.

The Opportunity

Reporting to the Director – Strategic Risk, Corporate Actuarial, the successful candidate will play a key role in leading and executing risk management initiatives related to climate perils and the impact of climate change on the company’s operations. This role combines advanced analytical work with strategic thinking, solution design, and cross‑functional influence.

What you Bring

Help lead the monitoring and assessment of emerging catastrophe and climate‑related risks impacting the company’s portfolio, capital position, and long‑term strategy.
Drive research and thought leadership on climate‑related hazards and human‑driven factors (e.g., urbanization, mitigation, land‑use change), evaluating their impact on exposure, vulnerability, and insured loss outcomes.
Design, build, and interpret advanced analytical workflows using geospatial and climate datasets, leveraging programming languages (e.g., Python, R) and spatial analysis tools (e.g., GIS platforms) to generate decision‑ready insights.
Lead the development, calibration, validation, and ongoing enhancement of catastrophe and climate risk models, ensuring methodological soundness and alignment with internal risk frameworks and business needs.
Translate complex analytical findings into clear, actionable recommendations, presenting results through concise written deliverables, executive‑level presentations, and dashboards tailored to senior leadership and non‑technical stakeholders.
Partner closely with actuarial teams (Reserving, Capital, Planning) and enterprise functions (Finance, Reinsurance, ERM) to shape risk perspectives, inform strategic decisions, and respond to ad‑hoc risk‑related questions.
Identify and champion improvements to data, processes, and analytical approaches, helping to evolve the team’s capabilities and ensure scalable, efficient, and consistent risk analysis.
Provide informal leadership and oversight, including peer review of analyses, coaching of junior team members, and contributing to a collaborative, high‑performing, and learning‑oriented team culture.

What you Bring

University degree in Actuarial Science, Mathematics, Statistics, or a related quantitative discipline.
Completion of at least five CAS exams (or equivalent actuarial credentials) and typically 3+ years of actuarial or related risk analytics experience within the insurance industry.
Advanced programming and analytical skills, particularly in Python (e.g., pandas, NumPy, SciPy, scikit‑learn) and/or R, with the ability to design production‑quality analytical solutions.
Strong experience working with large, complex, and imperfect datasets, including climate, exposure, and socioeconomic data, with a disciplined approach to validation and quality control.
Demonstrated ability to independently lead projects, make sound analytical judgments, and balance technical rigor with practical business considerations.
Proven track record of influencing stakeholders and collaborating effectively across functions in a matrixed environment.
Excellent communication, organization, and prioritization skills, with the ability to operate confidently in a fast‑paced, ambiguous setting.
A strong sense of ownership and accountability, coupled with intellectual curiosity, strategic thinking, and a desire to translate analysis into measurable business impact.

Salary Range : $92,000-$142,000

Actual salary for the role may vary depending on work location of the successful candidate and other factors including but not limited to, skills, education, experience, working conditions and the local labour market.

This position is being posted to fill an existing vacancy.

Interested in this role, but don’t meet every requirement? We encourage you to apply! We know from experience that a candidate doesn’t need 100% of the qualifications listed to bring incredible value to our team. We’re actively seeking diverse backgrounds and perspectives to help us make insurance better. At Definity, inclusion, diversity, and equity aren’t just “nice to have” — they’re essential to our success.

What’s in it for you?

Hybrid work schedule for most roles
Company share ownership program
Incentive Program - Eligible employees may participate in various incentive plans which are paid out at the discretion of the company and subject to individual and company performance.
Pension and savings programs, with company-matched RRSP contributions

Focus on inclusion with employee groups, support for gender affirmation surgery, access to BIPOC counsellors, access to programs for working parents

Go ahead and expect a lot — you deserve it.

It’s better here — but don’t take our word for it. Definity was named by Great Place to Work® as one of the Best Workplaces™ in Canada for women, for youth, and for inclusion.

Our inclusive work environment welcomes diversity and supports accessibility. If you require accommodation at any time during the recruitment process, please let us know by contacting [email protected].
