About Protera

Welcome to Protera Technologies, where we’re reimagining how SAP-centric organizations work in the cloud. Since 1998, we’ve been pioneers in bringing SAP and related applications to the cloud—think Microsoft Azure and AWS. Our global crew, spanning the US with offices in Chicago (HQ), Athens, Greece, Barcelona, Spain and Mumbai, India, is on a mission to make IT smoother, faster, and more fun for our clients.

But here’s the thing: we’re not your typical “serious tech company.” While we’re obsessed with delivering top‑notch IT solutions, we’re all about keeping it real, approachable, and enjoyable. We work hard, but we also play hard—whether we’re collaborating on cloud optimizations, enhancing security, or just hanging out as a team.

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.

What You’ll Do

The Senior SAP Engineer – Core will be responsible for designing, building, enhancing, and optimizing clean‑core SAP S/4HANA extensions and ABAP‑based services across complex enterprise landscapes. This role requires deep hands‑on engineering capability, modern ABAP proficiency, and the ability to collaborate across SAP and BTP technology stacks.

You will work across the following areas:

• Advanced ABAP OO development, including refactoring legacy custom code into modern, maintainable clean‑core patterns
• ABAP RESTful Application Programming Model (RAP) for both managed and unmanaged scenarios, including behavior definitions and service binding models
• CDS‑based domain modeling, including ABAP CDS, analytical/consumption views, annotations for OData/UI, and semantic modeling best practices
• OData V2/V4 service design, performance tuning, service exposure patterns, and backend optimization for scalable UI consumption
• SAP BTP integration patterns, spanning CAP ABAP interoperability, side‑by‑side extensions, event‑driven architectures, and hybrid S/4 + BTP design
• 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.

• Solid debugging capabilities: ABAP debugger, dumps (ST22), performance analysis (SAT, SQL trace)
• Familiarity with the S/4HANA data model, including key simplification topics
• Experience with transport management and the SAP development lifecycle
• Understanding of authorization concepts and security basics

Ability to follow clean‑core principles and SAP’s extension guidelines
