About the Role

As a Technical Account Manager (TAM), you will be the primary technical point of contact for our merchants after their initial go-live.

You will help monitor merchant technical health, support incident management, answer ongoing technical questions, and guide merchants through future technical evolutions.

For DEUNA’s premium and key accounts, the TAM plays a critical role in making sure merchants feel technically protected, proactively monitored, and confident operating on our platform.

Your mission is to help ensure every merchant is operationally stable, technically satisfied, and continuously improving on DEUNA.

Be the main technical contact after go-live

• Help merchants understand technical flows, configurations, integrations, and platform behavior.

• Coordinate internally with Product, Engineering, Support, Operations, and Account Management when merchant needs require cross-functional support.

Support technical incident management

Drive merchant technical improvements
