Senior Backend Engineer - Identity Lifecycle
Professional Overview
Join SumUp's pivotal Identity Lifecycle Mission as a Senior Backend Engineer, where you'll be at the forefront of shaping the foundational building blocks of the merchant journey. This critical role involves working on everything from initial onboarding and identity verification to robust KYC/KYB processes and comprehensive customer identity management. You'll contribute to a major transformation, moving beyond fragmented legacy systems to construct a coherent, scalable platform featuring shared data models and reusable services.
This isn't just about maintaining existing systems; it's an opportunity to significantly influence the future of our identity platform. You'll modernize critical services and lay down resilient foundations that can effortlessly support new regulations, markets, and product innovations. Your expertise will be vital in bringing together disparate capabilities into a unified, high-performing ecosystem, ensuring SumUp can grow securely and efficiently.
Working in a highly collaborative environment, you'll engage with diverse teams including Product, Design, Compliance, Risk, and Operations. If you thrive on solving complex backend challenges, are passionate about improving system reliability, and excel at building scalable solutions that empower other teams, this role offers a unique chance to make a profound and lasting impact at SumUp.
Key Responsibilities
- Design, build, and operate scalable backend services, APIs, event-driven workflows, and system integrations.
- Build reusable capabilities that power merchant onboarding, identity verification, and KYC/KYB regulatory data collection.
- Drive reliability and resilience across critical services through better observability, failure handling, incident response, and long-term risk reduction.
- Work primarily with Go, while maintaining and progressively modernising existing services written in Java.
- Evolve domain models and service boundaries while reducing legacy complexity, duplicated logic, and tightly coupled integrations, always with a pragmatic, incremental mindset.
- Own your work end-to- end, from technical design and implementation to rollout and production follow-up.
- Work across team and domain boundaries, turning ambiguous product and regulatory requirements into clear, scalable technical solutions.
- Review code and designs, mentor engineers, and help raise engineering standards across the mission.
