Description
The Partnership and Enterprise squad is building the infrastructure that powers SumUp's partner channel, a business that supports around 800 active partners and is growing fast. As the squad's Senior Full-Stack Engineer, you'll take end-to-end ownership of the Partner Portal, the product that sits at the heart of how SumUp's partners manage their merchants, fees, and operations. This is an opportunity with real scope: you'll shape technical direction, collaborate closely with CRM engineers and product stakeholders, and ship features that directly reduce operational friction for the teams driving SumUp's sales growth.
What you'll do:
- Build and own the Partner Portal's frontend using React, TypeScript, and Next.js, creating fast, reliable, and well-structured user-facing experiences
- Design, build, and maintain the services and microservices that power the portal, ensuring reliability and high availability at scale
- Write and maintain back-end APIs, services, and data pipelines in TypeScript and Go that are scalable and built to support a fast-growing global platform
- Develop fee management functionality and other high-impact features that directly reduce the administrative burden on partner management teams
- Implement monitoring and alerting, and follow up on incidents to keep the platform stable and performant
- Collaborate with colleagues and stakeholders across the Partnerships team to identify areas of improvement, collect feature requests, and shape solutions
- Actively contribute to code reviews, team ceremonies, and chapter rituals, sharing context and knowledge across engineering disciplines to avoid silos
You'll be great for this role if:
- You have proven experience with TypeScript and React, building scalable, production-grade full stack applications using frameworks such as Next.js, Remix, Nuxt, or similar
- Solid experience designing and working with RESTful APIs and complex microservice systems, with comfort navigating and refactoring large codebases
- Solid knowledge of Go, or strong experience with another backend language such as Node.js, used to build reliable, performant backend services
- Experience as a Kubernetes user, with familiarity in CI/CD pipelines and infrastructure tooling such as Terraform
- Comfort working closely with CRM systems or adjacent tooling (e.g. Salesforce), and an openness to bridging the gap between CRM engineering and full stack development
- A product mindset, connecting technical decisions to real business outcomes, and a genuine sense of ownership over the features you build from planning through to maintenance
Why you should join SumUp:
- š Opportunity to work with SumUppers globally on large-scale fintech products used by millions of businesses worldwide, from our Berlin office. This involves an office-first setup
- š Commitment to Diversity and Inclusion: be part of a workplace that values and promotes diversity, fostering an inclusive environment where everyone's perspectives are respected and embraced
