Senior Backend Engineer — Global Expansion

About the team

The Global Expansion Acquiring Squad is the engine behind SumUp's growth into new markets — integrating local payment acquirers, enabling merchant onboarding, and ensuring transactions flow reliably across countries like Mexico, Canada, New Zealand, and Australia. This role sits at the heart of that mission, owning critical backend systems while also shaping how the squad works — building AI agents and developer tooling that make the entire team faster and smarter. If you're a backend engineer who wants real ownership, enjoys working in ambiguous and complex environments, and is genuinely excited about teaching AI how your codebase works (not just using it for autocomplete), this role is for you.

What you'll do

Design and build scalable backend services in Golang and Kotlin, covering merchant onboarding, transaction processing, and reconciliation across multiple acquirers and markets
Lead technical investigations for new market launches and mentor engineers on the team
Configure and maintain AI coding assistants (Cursor, Copilot, Continue) with team-specific rules, framework conventions, and testing patterns — so generated code fits our systems, not generic templates
Build AI agents that automate repetitive development tasks, such as generating integration stubs, updating OpenAPI specs, and flagging idempotency violations
Keep documentation accurate and AI-accessible, so the team spends less time answering "how does X work?" and more time shipping

You'll be great for this role if…

Strong proficiency in Golang (primary) or a JVM language such as Java or Kotlin, with experience building distributed, fault-tolerant backend systems
Experience configuring AI coding assistants at a team level — defining rules, prompts, and context packages that produce consistent, framework-compliant output
Solid understanding of idempotency, retry policies, and transaction safety in payment or financial systems
Comfort working across multiple teams and domains simultaneously, navigating ambiguity and influencing without direct authority
A track record of taking ownership in complex, cross-functional environments where the scope isn't always clearly defined

Why you should join SumUp

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
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
Enrolment onto our Virtual Stock Option programme: you will own a stake in SumUp's future success
A dedicated annual L&D budget of €2,000 for your individual development, which can be used to attend conferences and/or advance your career through further education
A corporate pension scheme where we match up to 20% of your contributions
️ Generous time off: enjoy 28 days of paid leave plus public holidays and special leave days
️ Numerous other benefits such as Urban Sports Club subsidy, Kita placement assistance, subsidised office lunches
Break4me: 1-month sabbatical after 3 years of service
Referral Bonus: earn additional rewards by referring talented individuals to join the SumUp team
