HRS reinvents how businesses WORK, STAY AND PAY.  Counting more than 5.000 corporations and 40% of Fortune 500 companies in our customer base, HRS has emerged as the most trusted platform of digital software solutions in business travel hospitality worldwide.

The HRS platform is composed of three engines that each optimize one core building block along the corporate hospitality supply chain: Intelligent Procurement, Smart Booking, and Invisible Payment. Through the integration of those engines into one large data-driven platform approach, our Lodging-as-a-Service value proposition enhances the satisfaction of corporate employees and travelers, delivers the highest grade of process automation for corporate stakeholders, and ensures the strongest compliance end-to-end.


The HRS PAY business unit is hyper-focused on driving not only the HRS “flywheel” via the powerful combination of STAY and PAY, but also our own PAY flywheel whereby both corporate clients and third-party partners benefit from leveraging HRS PAY’s technology and capabilities. The more corporate clients use PAY, the more third-party partners such as banks, card issuers, ERPs, booking platforms and other financial service providers want to partner and collaborate with us, and this drives further commercial growth for PAY by monetizing those partnership streams. HRS PAY is a “tech fin” in that we provide the technology that powers the payment workflow as well as delivers the highest level of available payment data to enable our customers to make intelligent decisions around their program spending. Only HRS PAY offers this powerful combination of automation, data optimization, and payment on-the-go technology all in one platform.


In the responsible position of the Senior Java Backend Engineer, the future position holder is responsible to build the next generation of APIs and Services. As a Senior Java Backend Engineer, you are responsible for the development and maintenance of our backend components to ensure stabilization and enable our exclusive services for our customers.
