About the Role

SumUp is seeking a Systems Engineer Manager to establish and lead the Systems Engineering function within Corporate IT. This role involves owning and maturing the identity infrastructure built on Microsoft Entra ID, and driving the consolidation and standardization of core business platform configurations. The ideal candidate is a technical strategic thinker focused on improving stability, observability, and performance.

Responsibilities

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.

Requirements

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.
Proven track record of automating lifecycle processes (JML).
Proficiency in scripting (PowerShell, Bash, or Python).
Ability to design systems that solve access problems before they reach the helpdesk.
Expert knowledge of cloud-first identity principles like SCIM and OIDC.
Experience acting as a technical lead, managing high-level administrative permissions, and navigating "Least Privilege" environments.
Ability to see technical debt and inconsistent configurations as an opportunity to create structure.
