Your initial portfolio will include strengthening Trust & Safety operating processes following the evolution of our detection and investigation capabilities.

[Long-term] Diagnose and improve end-to-end marketplace operations Identify and prioritise systemic operational problems using performance data, user friction, frontline insight, control failures and business impact. Analyse end-to-end user journeys across organisational boundaries rather than optimising one team’s part of the process in isolation.
