About the Platform Team:
At SumUp, we're building the financial ecosystem that empowers over 4 million merchants worldwide to get paid, manage their business, and grow. Within our Platform Tribe, the Core Apps domain provides the foundation for our web and mobile applications.
As Engineering Manager, you'll lead two squads at the heart of this mission:
Web Platform – the team behind our core dashboard infrastructure. They make sure SumUp's web experiences are fast, reliable, and scalable, while giving developers the tools and frameworks they need to move quickly and with confidence.
* Design System – the team shaping SumUp's design language into a world-class library of UI components and patterns. Their work ensures that every product feels cohesive, accessible, and beautifully crafted — no matter where it lives in our ecosystem.
Together, these teams are redefining how we build products at SumUp: improving performance, creating seamless developer experiences, and evolving our brand identity. Joining them means having a direct impact on both our internal engineering community and the millions of merchants who rely on SumUp every day.
What you'll do
* Lead the Web Platform and Design System squads, driving strategy, execution, and team development.
* Collaborate closely with the Mobile Platform Engineering Managers to align on best practices and improve SumUp's Core Apps.
* Improve web performance and developer experience by reducing CI times, addressing tech debt, and optimising infrastructure.
* Provide and maintain a high-quality UI library that powers all SumUp applications, while evolving our design language and contributing to brand refresh initiatives.
* Partner with engineering, product, and design stakeholders to set standards that improve quality, speed, and consistency across all frontends.
* Mentor and support engineers in their growth and development, fostering an inclusive and empowering team culture.
* Drive high-impact initiatives that align with company priorities such as Growth, AI Enablement, and Product Identity.
You'll be great for this role if you have:
* 6+ years of software engineering experience, including at least 2 years of technical leadership.
* Hands-on development background with modern web technologies (JavaScript/TypeScript, React, ) and at least one fullstack framework, Remix, SvelteKit).
* Understanding of mobile technologies (Swift, Kotlin, Objective-C, or Java) is a plus.
* Experience with design systems and effective collaboration with product/design teams.
* Proven ability to grow and lead engineering teams through coaching, mentoring, and career development.
* Strong skills in system and API design within microservice architectures.
* Solid understanding of cloud infrastructure and web performance optimization.
* Excellent communication skills, able to align diverse stakeholders around shared goals.
* A founder's mentality: proactive, pragmatic, and eager to simplify and automate where possible.
