As a Senior Software Engineer, your primary value lies in tackling problems at scale by building and maintaining the high-performance serving layer for our ML models. A core part of this is integrating multiple microservices in real-time to fetch external data, apply business rules, and enforce operational constraints to enrich model predictions and shape the final decision. This critical layer directly impacts the algorithm's logic, leading to best-in-class efficiency and service across the Delivery Hero network.

• Scale and Perform: Architect and build solutions at scale, optimizing for low-latency performance and high efficiency in production.

• System Ownership: Take end-to-end ownership of the backend serving layer, from design through deployment and maintenance.

• Collaborate and Optimize: Work closely with Data Scientists, Analysts, and Data Engineers to understand needs and build solutions that optimize their workflows and transition models to production.
