Back-end Developer (Node.js)


Back-end Developer (Node.js)

Introducing Flex-Appeal

Hello there! We’re Flex-Appeal, a fast growing start-up located in Rotterdam. We are on a mission to redefine the way organisations engage their frontline employees.

Nowadays, 75% of the worldwide workforce is working on the ‘frontline’. These are industries like retail, restaurants, hotels and many more. There is a huge gap between the frontline employee and the rest of the organization. Research says that 87% of those employees don’t feel engaged at work. Organizations feel the need to engage their employees but don’t have the right tools to achieve this.

We believe we can change that. That’s why we’re building a completely new and mobile “employee experience” platform. Using our modulair platform organisations are able to engage, communicate and train their employees and much better!

We’re already working with great companies such as Gamma, Karwei, the Amsterdam Arena, New York Pizza and Albert Heijn. Our goal is to engage all 2 billion frontline workers worldwide with our platform. This requires a team of very talented and ambitious people, like you!
