This is not a generic SAP support role. If you have spent time in enterprise SAP environments and you want to go deeper, debugging real production issues, working alongside product engineers, and building expertise in a product used by some of the world's most complex organisations, this is worth reading. As an L2 Support Analyst at Basis Technologies, you sit at the technical heart of the customer experience. You take the hard cases, the ones that require real root cause analysis, ABAP debugging, and transport management expertise, and you solve them. You work directly with customers' technical teams, and when a defect needs escalating, you hand it to L3 Engineering with your analysis already done. Product depth, not project breadth. If you have come from a consultancy or SI background, you will know what it feels like to move on before you fully understand what you built.

Are you an SAP engineer who has built software that shipped to real customers not just customised a single company's system? At Basis Technologies, we're looking for a Senior SAP UI5 Developer who thinks in products, not projects. Basis Technologies powers intelligent change management for SAP-run enterprises worldwide. You wouldn't be customising SAP. You'd be writing software that SAP-run businesses depend on to keep their production systems stable. This is a builder's role. Clean Core is a first-class principle here not a constraint we're retrofitting around, but the foundation we build on. UI5 is the primary front-end layer, and OData services and REST APIs are the standard integration pattern. ABAP still matters this is a deep SAP platform product but the mindset is product engineering, not enterprise customisation. If that distinction resonates with you, keep reading.
