What you’ll do

As a Senior Optimization Consultant, your role is to provide expert knowledge and insights to Airwallex’s largest merchants.

• You will lead discussions with customers on their existing payment performance, opportunities to improve and requirements to implement

• You will train internal stakeholders (e.g., Sales teams) on how to lead discussions with customers and prospects, providing them with tooling as required

• You will liaise with our Product teams to ensure that they understand customer feedback and incorporate your learnings into their roadmaps

• You will support engagements with external stakeholders (e.g., card issuers)
