About Protera

Welcome to Protera Technologies, where we're reimagining how SAP-centric organizations work in the cloud.

At Protera, we believe in empowering SAP-centric organizations with the best tools and tech to drive growth, and we love what we do. Our values? Simple: stay curious, stay authentic, and make meaningful connections. We celebrate wins big and small, whether it's a successful project or a fun team event.

If you're looking for a place where tech and fun collide, come join us and see what makes Protera a great place to work.

  • Event-driven ABAP using Business Events, RAP event handlers, and event-based orchestration across systems
  • Enterprise security architectures, including OAuth2 connectivity, principal propagation, role/authorization concepts, and secure extension strategies
  • Performance and scalability optimization in S/4HANA, including SQL pushdown, AMDP considerations, memory/performance tracing, and advanced debugging
  • Cross-stack engineering collaboration with CAP/Node.js services, SAPUI5/Fiori teams, and the Integration Suite
  • Modern debugging and distributed tracing, working across ABAP, SAP BTP services, and integration touchpoints
  • Mentorship and engineering leadership, including code reviews, solution design support, and participation in architectural discussions

This role requires strong technical leadership, hands-on delivery, and the ability to shape high-quality, clean-core SAP solutions.
