Engineering and Product

Engineering and Product Be empowered to build things that matter Explore open roles Who we are Our global community is made up of hundreds of talented Engineers and Product Managers. We collectively build, plan and fine-tune the technology that drives SumUp and empowers small businesses around the world. We’re on a mission to redefine financial inclusion through accessible technology and products. Our philosophy We believe real innovation happens when barriers are removed and teams are empowered to own their work. Our agile framework allows us to adapt quickly and foster an environment fuelled by curiosity. We’re efficient, collaborative and constantly improving the way we work through self-reflection. Our structure We’re composed of several teams we call tribes. Each tribe consists of several smaller, cross-functional squads. Equipped with the necessary skills to realise their missions, squads are completely autonomous. Whether it’s building a product for our merchants or an internal platform, each team is the owner of their domain. "SumUp has been incredibly supportive of my career progression. Starting as a Senior Engineer and moving up to Staff Engineer shows the company’s commitment to my development. The opportunities for mentoring and cross-team collaboration have been invaluable. I’ve also had the chance to work on diverse projects outside my usual scope, which has helped me grow in different areas." Thiago Penna, Staff iOS Engineer What makes us unique Innovation Exercise your mind on a daily basis by solving complex problems and building products for the ever-evolving world of fintech. Autonomy Be empowered with the freedom and resources necessary to own your work from start to finish within your team. Purpose Add an extra layer of purpose to your daily grind by directly empowering small business owners through your work and seeing real impact. Our technology Following a platform-first approach, we're building our products and services with open APIs and are structured into a microservices-based architecture. We’re always open to exploring new languages or services. Here’s a glimpse of the technologies we currently use. Elixir Golang Javascript/Typescript Kotlin Objective-c Swift C/C++ Python Kafka Kotlin Multiplatform Kubernetes React Helm Gradle Ktor Arrow.IO Docker Github Package Manager/Container Registry Java Hack Week We're on a mission to lead payment solutions for small merchants globally. To achieve that, we need to deeply understand the user's needs and foster innovation among our tech teams to deliver cutting-edge products. Hack Week is an opportunity to unite members of our Engineering, Product and Design community in one place to step away from their daily tasks, collaborate, unleash creativity and bring new ideas to life.
