Join ING’s Global Customer Data Management (GCDM) tribe as a Senior Java Engineer. You’ll build scalable, high-performance systems that power customer journeys across retail and wholesale banking worldwide.

In this position, you will be at the heart of our scalable technology platforms, responsible for delivering common banking functionalities used in most of the propositions ING offers to its customers. You will work on the Party and Agreement Management (PAM) system.

OnePAM is the global service that provides Master Data Management solutions for managing customer data. The OnePAM service is provided by the Global Customer Data Management tribe (GCDM) and is the customer data store and data layer of the Banking Technology (Touchpoint) Platform. OnePAM supports all ING business lines and entities by providing data and business services to manage Master Party Data, incorporating Touchpoint technology and Global Reference Data Management. It enables consumers worldwide to connect to global services and ultimately decommission local Data Management systems.

The Touchpoint Platform is a critical enabler of ING’s strategy to become one truly global bank and is a key success factor on our path to rapidly transform from a traditional bank into a next-generation financial services platform that extends beyond banking.

Stand-by shifts

Business-critical systems, such as client processes, payment processes, software applications, and websites, require 24/7 accessibility and availability of several groups of employees to act quickly during unforeseen circumstances, such as calamities or incidents. For these employees, ING has set up a stand-by regulation. To compensate for the inconvenience of being available at this time, a stand-by compensation is awarded.

For this role, you will be designated for stand-by shifts and need to be available for incidents outside your regular working hours. Stand-by shifts occur approximately 3–4 weeks per year. You’ll be compensated and supported with clear escalation procedures.
