• Support impact analysis and estimation for new product launches, product changes, and regulatory updates affecting illustrations.

• Provide technical guidance, code reviews, and mentoring to developers working on the illustration engine or related systems.

• Maintain clear technical and calculation documentation covering implemented logic, assumptions, and design decisions to reduce key‑person risk.

• Support QA and UAT activities by explaining calculation behaviour, assisting with defect triage, and validating fixes.
