Sumup

About the role SumUp is looking for a Systems Engineer Manager to join our Corporate IT team. In this role, you will report to the Head of Global IT. You will establish and lead our Systems Engineering function within Corporate IT, establishing the discipline from the ground up. You will own and mature SumUp's identity infrastructure, built on Microsoft Entra ID, and drive the consolidation and standardization of our core business platform configurations. We are looking for a technical strategic thinker who thrives in bringing structure to complexity. You won’t just be "keeping the lights on"; you will be actively improving stability, observability, and performance. About the team The Corporate IT team currently consists of a diverse group of System Administrators and outsourced support across the EU and the Americas. Our mission is to ensure every SumUp employee can access the tools they need safely and efficiently. We provide the "digital keys" to the company, ensuring that identity and access are seamless enablers of work rather than hurdles.  We believe in high accountability, technical excellence, and fostering a culture where IT is treated as an engineering discipline. If you are excited about building unified identity platforms, leveraging cutting edge technologies like AI and scaling internal engineering in a complex, multi-region fintech environment, we want to hear from you. What you’ll do * Design conditional access policies, manage identity lifecycles, and ensure SSO health across a complex Microsoft Entra ID environment. * Develop scripting and workflow tooling to reduce manual toil and increase reliability across the organization. * Drive the adoption of AI-powered tooling to automate routine processes and scale the team's output beyond human hours. * Partner with Endpoint Management to ensure seamless integration between identity, access, and device management across the fleet. * Govern access to AI platforms and tooling (e.g. Copilot, Cursor, Langdock) - permissions, data boundaries, audit trails * Lead the consolidation and standardization of core business platform configurations to bring consistency to our fast-growing landscape. * Build a team where you will set clear expectations and actively support the career growth of your team members. * Partner closely with Security & Compliance for access controls, the People Team for "Joiner-Mover-Leaver" processes, and Engineering teams for secure tool access. * Own the IT service queue for systems-level issues, triaging and resolving with engineering rigour rather than a purely reactive support mindset. You'll be great for this position if: * You have 5+ years of experience in IAM or Systems Engineering, with deep expertise in tooling like Azure/Entra ID, Okta, or OneLogin. * Familiarity with governing non-human identities and service accounts at scale -- this is increasingly critical as AI tooling proliferates and is a meaningful filter for the right candidate * You have a proven track record of automating lifecycle processes (JML) and proficiency in scripting (PowerShell, Bash, or Python). * You design systems that solve access problems before they reach the helpdesk and have expert knowledge of cloud-first identity principles like SCIM and OIDC. * You have experience acting as a technical lead, managing high-level administrative permissions, and navigating "Least Privilege" environments. * You see technical debt and inconsistent configurations as an opportunity to create structure rather than a hurdle to avoid. 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 📚 A dedicated annual L&D budget of €2,000 for attending conferences and/or advancing your career through further education. 🚀 Enrolment onto our VSOP program: You will own a stake in SumUp’s future success 💶 A corporate pension scheme where we match up to 20% of your contributions 🔄 30 Days Sabbatical: Enjoy the unique opportunity to take a well-deserved break with our 30 days sabbatical benefit after completing 3 years of employment with SumUp. 🔗 Referral Bonus: Earn additional rewards by referring talented individuals to join the SumUp team. 🚵🏾‍♂️ Numerous other benefits such as Urban Sports Club subsidy, Kita placement assistance, relocation assistance, subsidised office lunches.
