Senior Software Engineer / Technical Architect

Project Overview
ApeiroRA is SAP's contribution to a sovereign, open European cloud-edge stack, developed in the open and donated to the Linux Foundation.
As part of its security workstream, the team is developing an enterprise-grade audit logging solution based on OpenTelemetry. The initiative focuses on defining standardized semantic conventions for audit events and ensuring reliable delivery guarantees, so that no audit signal is lost between the source and the final storage destination.
The core engineering work is already underway. We are looking for an experienced Senior Software Engineer / Technical Architect to join the team for approximately six months, working closely with development teams and stakeholders across the ApeiroRA ecosystem to drive adoption of the solution.
Key Responsibilities
Engage with adopter teams across the ApeiroRA platform to understand their existing audit logging processes, including how they generate, transmit, and consume audit-related signals.
Gather, analyze, and translate stakeholder feedback into prioritized technical and functional requirements.
Validate the existing solution architecture and design against real-world adoption needs.
Demonstrate the current capabilities of the solution, identify technical gaps, and collaborate with the engineering team to address them.
Prepare technical documentation, architecture explainers, demos, and other materials for the open-source community and internal SAP stakeholders.
Act as the main point of contact for audit logging within the ApeiroRA ecosystem.
Bridge communication between adopter teams and developers, ensuring that feedback and requirements are reflected in the product's ongoing development.
Required Skills & Qualifications

Hands-on knowledge of OpenTelemetry and its ecosystem.
Understanding of reliable data delivery mechanisms, including delivery guarantees and ensuring data integrity across distributed systems.
Strong analytical and problem-solving skills, with the ability to translate business and technical requirements into actionable development tasks.
Excellent written and verbal communication skills, with the ability to explain complex technical concepts to both technical and non-technical audiences.
