ERP & IT Systems Administrator

What you'll do

• Own SAP Cloud ERP end-to-end, with a primary focus on SAP S/4HANA Cloud, Public Edition — from fit-to-standard setup and role design to stable operations, release management, training, and continuous improvement 

• Build SAP best-practice processes from scratch across Hypersonica’s manufacturing value chain, including finance, procurement, supplier management, sales/logistics, manufacturing, serial/batch traceability, warehousing, inventory, quality, and maintenance — turning SAP into the operational “single source of truth” 

• Own the SAP operating model: super-user network, process documentation, change control, release/regression testing, issue triage, root-cause fixes, and a prioritized improvement backlog 

• Configure and continuously improve SAP Sales Cloud and SAP SuccessFactors, ensuring clean processes, reliable integrations, strong adoption, and high data quality across commercial and people operations 

• Own business-critical integrations between SAP and adjacent tools — e.g. identity/access, finance/reporting, HR, CRM, procurement, inventory, document management, and relevant manufacturing/engineering systems in coordination with IT infrastructure and consistent with applicable compliance frameworks and standards 

• Participate actively in IT governance processes including the change advisory process, ISMS asset ownership, access model reviews, and architecture decisions that span business applications and coreIT infrastructure 

• Act as the business owner for enterprise SaaS and business applications beyond SAP, including vendor selection support, configuration, license management, integration requirements, user enablement, and lifecycle governance 

• Take responsibility for application administration and tooling operations as integral part of the IT organization, but focused on business systems, not core infrastructure, endpoint management, or Kubernetes/Linux operations 

• Build lightweight but robust internal workflows and automations, forms, approval flows, reporting dashboards, and structured data repositories where a full ERP workflow is not yet appropriate 

• Own business systems data quality: master data standards, user access hygiene, approval workflows, audit trails, dashboards, and exception reporting across SAP and adjacent SaaS tools

• Partner with Finance, Supply Chain, Manufacturing, People, Sales, IT, and Engineering teams to translate messy operational needs into scalable, secure, and usable systems 

 

Who you are

• You have a proven track record implementing and operating SAP S/4HANA Cloud, Public Edition in a real business environment — ideally in manufacturing, industrials, aerospace, defence, automotive, hardware, or another complex physical-product company 

• You understand what “fit-to-standard” really means: you can challenge customisation requests, guide teams toward best practice, and configure clean processes that scale rather than creating brittle workarounds 

• You have hands-on experience with SAP Sales Cloud and SAP SuccessFactors, and you are comfortable owning both business configuration and day-to-day operational support 

• You are strong across business applications beyond SAP: SaaS administration, integrations, workflow automation, access models, vendor coordination, data governance, reporting, and user adoption 

• You are technical enough to work with APIs, SSO/identity concepts, data models, permissions, integrations, and reporting logic — without needing to own the DevOps or endpoint-management stack 

• You extend the IT team’s capability into the business application and enterprise systems layer. While the broader IT teams owns core infrastructure, platform services, and endpoint operations, you bring the functional architecture and administration expertise that turns SAP and adjacent tools into reliable, governed, and well-integrated business systems 

• You are an operator, not just an administrator: you fix root causes, document clearly, prevent repeat issues, train users, and keep systems clean, secure, and audit-ready 

• You thrive in a fast-moving hardware company where systems must support speed, traceability, security, and disciplined execution — without adding unnecessary bureaucracy
