About this role

Why Reelo In today’s customer centric world, it’s important for every business to market like the best brands in the world. As competition for customers’ attention increases, it has never been more important for small and mid-market F&B and retail businesses to have 360° view of the people that keep them in business. But collecting, understanding and taking action on customer data is riddled with market, resource, and technology challenges. Solving these challenges is why we get up in the morning. Reelo is the new-age customer marketing platform for restaurant & retail businesses to grow their revenue, get more customers and build a stronger brand, in an incredibly simple manner. We understand that it's easier than ever to start a restaurant & retail business, it’s harder than ever to grow it. Specifically, most of these businesses have two challenges with growth: 1. Getting people to make their first purchase. 2. Getting those people to come back and buy again (and again and again). These businesses and their teams already have 1,000 things to do — wrestling with overly complicated marketing tools doesn’t need to get added to the list. Our SaaS platform makes it fast & easy for businesses to understand more about their customers and continously engage with them in a smart & automated way - making them look like a professional without the effort. There is a massive opportunity in front of us. We’re building a business that is big, meaningful, and lasting. For that, we’re building a strong, diverse team of curious, creative people who want to find purpose in their work and support each other in the process. If that sounds like you, we’d love to hear from you. 👉🏻 Read more on  https://www.reelo.io About the Opportunity We are looking for a Backend Developer (MERN Stack) to design, build, and scale backend systems that power modern web and mobile applications.
