Zusammenfassung

Nebius is hiring a Staff Software Engineer to advance the runtime systems of our agent-native search platform. You will build low-latency, high-throughput services handling real-time queries and optimise every layer from request handling to data access.

You will work on critical performance paths with strict latency budgets and collaborate with indexing and ML teams to keep ML logic decoupled from core systems.

Qualifikationen

• 8+ years of experience as a software engineer in production backend systems.
• Strong hands-on expertise in C++ or Rust in real-world, high-load services.
• Experience delivering low-latency, scalable backend systems.

Aufgaben

• Design, implement, and operate core runtime services for serving search queries at scale.
• Build and optimise request flows, including query processing, retrieval orchestration, and response assembly under strict latency budgets.
• Develop systems that maintain performance and predictability under high load.
• Optimise CPU, memory, and data access patterns in performance-critical paths.
• Ensure reliability, observability, and predictability across production services.
• Build well-tested systems with clear responsibilities and interaction contracts, while remaining flexible as architecture evolves.
• Define and implement observability primitives, including structured logs, metrics, traces, and latency breakdowns.
• Monitor throughput, latency, and resource usage, and drive improvements in performance and cost efficiency.
• Collaborate with indexing and ML teams to integrate retrieval and ranking components, keeping ML logic decoupled from core system internals.
• Support experimentation and iteration through controlled rollouts and rigorous benchmarking.
