Senior Backend Engineer
About the team
You'll join SumUp's Merchant Intelligence squad within the Engagement Mission — a newly formed team building foundational backend services that create a shared source of truth for product and merchant data across the business. The team is focused on two core services: Merchant Intelligence and the Product Catalog.
What you'll do
- Design, build, and evolve foundational backend services that create a shared source of truth for product and merchant data across SumUp, with a strong focus on scalability, reliability, and ease of adoption by internal teams.
- Develop and maintain robust APIs, data models, and integration patterns that enable teams across the business to access consistent and trustworthy product and merchant information.
- Build and improve data ingestion, aggregation, and event-processing pipelines that bring together signals from across the SumUp ecosystem.
- Write high-quality, maintainable backend code following engineering best practices for testing, observability, and production readiness.
- Collaborate closely with product managers, data teams, and engineers across SumUp to identify needs, solve complex data challenges, and turn them into effective technical solutions.
- Help define engineering standards, technical direction, and ways of working in a newly established squad operating in a complex and evolving domain.
You'll be great for this role if you have:
- Strong professional experience in backend engineering, building and operating reliable production systems.
- Solid experience with Golang and designing scalable backend services.
- Strong knowledge of API design, system design, and data modeling.
