Transaction Health Senior Analyst

We are looking for a Transaction Health Senior Analyst to join our Spend Operations team in Singapore. This is a senior individual contributor role for someone who wants to solve complex payment problems and help more good customer payments succeed.

You will use payment knowledge, data and stakeholder conversations to find the cause of payment problems. You will identify practical solutions and lead the work from the first signal to a measured result.

How You Will Contribute:

• Lead Investigations From Start To Finish: Find important payment problems from payments data, customer reports and stakeholder input. Use SQL, Python or a similar language to test hypotheses and find patterns.
• Find The Right Problems: Select work based on customer impact, materiality, evidence, ownership and a practical path to action.
• Design And Drive Solutions: Look beyond the first or most obvious solution. Identify practical levers across Product, Engineering, Risk, Operations, merchants, acquirers, processors and card schemes.
• Measure Results And Improve How We Work: Define the success measure before an intervention starts. Compare results before and after the action.

Qualifications:

• You have strong practical data skills. You can use SQL, Python or a similar language to investigate complex data.
• You understand payment systems and can reason across the full payment flow.
• You can form clear hypotheses and test them with incomplete or conflicting evidence.
• You can find and assess several possible levers, including solutions that do not need a new technical build.
• You can influence Product, Engineering, Risk, Operations and external payment partners.

Nice To Have:

• Experience with 3DS, payment authorisation, card acceptance, decline behaviour or post-authorisation processing.
• Experience working with merchants, acquirers, processors, card schemes, wallets, ATM operators or terminal providers.
• Experience with root-cause analysis, before-and-after measurement or controlled tests.
• Experience writing decision briefs for senior stakeholders.
• Experience leading complex cross-team work without formal authority.
