SumUp helps businesses get paid effortlessly, process orders fast, sell online instantly, and manage money smarter. We build the tools that let merchants thrive and deliver outstanding customer experiences. But we don’t just simplify transactions — we’re reshaping the future of fintech.

Sofia has been the heart of SumUp’s payments platform since day one. For over a decade, our Payments Tribe — made up of cross-functional, autonomous squads — has powered secure, scalable payment processing for card-present and card-not-present (CNP) transactions in 36+ markets, helping millions of merchants grow, get paid, and thrive.

We’re looking for an Engineering Manager to lead and grow a team of talented engineers within our Payments domain, which is SumUp’s foundational product, underpinning everything else we do. You’ll collaborate closely with Product and Business partners to scale the backend systems behind SumUp’s global payments engine - securely processing millions of transactions daily and ensuring our merchants get paid quickly and reliably across all channels. Your work will directly impact the success and growth of millions of small businesses around the world.

If you're excited about high-scale systems, fintech innovation, and shaping the future of digital payments, we’d love to meet you.

What you’ll do:

• Shape technical direction: contribute to platform-wide decisions as part of the Payments leadership team and influence long-term technical strategy.
• Take ownership of technical delivery: define short- and long-term goals with Product, drive technical design and architecture discussions, and ensure timely, high-quality execution.
• Grow and support your team: provide coaching, feedback, and structured performance development while fostering a collaborative, high-performing culture.
• Promote cross-functional alignment: build strong collaboration across engineering, product, and business teams in a dynamic environment.
• Manage priorities and context-switching: coordinate shifting priorities across multiple teams or domains, balancing business needs with engineering focus.
• Drive engagement and knowledge sharing: lead initiatives like hackathons, cross-team projects and internal community events.
• Contribute hands-on: review designs and code when needed, and help solve complex backend challenges.
  
  

What we’re looking for:

• You have deep backend engineering experience and hands-on work with distributed systems, APIs, and databases. Experience with Go and cloud-native environments (preferably AWS) is a plus.
• You’ve managed engineering teams in complex environments involving multiple technologies, priorities, and cross-functional collaboration — ideally in high-reliability or fintech domains.
• You can manage multiple domains or teams with different focus areas, shifting context and priorities with ease.
• You’re a clear, effective communicator - able to simplify technical topics and build alignment and trust across diverse stakeholders.
• You use data and metrics to drive decision-making, monitor system health, and improve delivery.
• You lead with empathy and clarity, giving constructive feedback, developing people, and guiding teams through scale or change.
• You prioritize team success over individual silos, working to break down barriers between teams and foster a culture of collaboration and shared ownership.

Why you should join SumUp:

• Collaborate with SumUppers worldwide on large-scale fintech products used by millions, based in our Sofia office (office-first setup).
• Access a €2,000 annual L&D budget to attend conferences or advance your career through education.
• Participate in our VSOP program and own a stake in SumUp’s future success.
• Enjoy 25 days of paid leave (increasing with tenure), plus paid vacations for special occasions and a 1-month sabbatical every 3 years.
• Benefit from extra perks like health and life insurance, co-sponsored Multisport cards, childbirth/adoption bonuses, discounts, a referral program, monthly food vouchers, flexible benefits, and more.

Please note: This role requires the right to work in Bulgaria. We are currently not able to support visa applications or relocation for this position at this time.
