Description

  • Design, implement, and operate core backend components for the search system, including request-time services and background data pipelines.
  • Contribute to document ingestion, crawling, and preprocessing workflows based on source, domain, and freshness needs.
  • Build and evolve indexing and retrieval systems, including data formats, update strategies, and access patterns.
  • Implement and improve search request flows, including query processing, retrieval orchestration, and response assembly within strict latency budgets.
  • Build well-tested services and pipelines with clear responsibilities and interaction contracts.
  • Define and implement observability primitives such as structured logs, metrics, traces, and quality signals across online and offline components.
  • Support experimentation through feature flags, controlled rollouts, and online experiments.
  • Monitor throughput, latency, and resource usage, and improve performance or cost efficiency when needed.
  • Collaborate with ML engineers to integrate semantic retrieval and ranking models while keeping ML logic decoupled from core system internals.
  • Work with data analysts and product managers to translate product and quality goals into backend behavior and measurable metrics.

Requirements

  • 5+ years of experience as a software engineer working on production backend systems.
  • Hands-on experience with Go in real-world services; experience with C++ or Rust is a plus.
  • Experience building concurrent, high-load systems with an understanding of throughput, latency, and failure modes.
  • Familiarity with distributed systems fundamentals, including fault tolerance, load balancing, and horizontal scalability.
  • Experience operating code in production, including deploying, debugging incidents, and rolling back changes when necessary.
  • Ability to think systematically while making pragmatic tradeoffs when time or scope requires it.
  • Comfort working across system boundaries and reasoning end-to-end rather than within a narrow component.
  • Strong cross-functional communication skills with engineers, ML practitioners, analysts, and product managers.
  • Curiosity about modern developer tooling and experience using AI-assisted tools such as coding agents or ChatGPT.
  • Experience with backend systems for search, recommendation, ranking-heavy products, or similar platforms is preferred.
  • Experience building or operating data pipelines, ingestion systems, or indexing workflows alongside online services is preferred.
  • Practical exposure to ML-backed systems, including classical ML pipelines or LLM-based services, is preferred.
  • Experience with AI agent architectures, tool-calling systems, or agent-oriented workflows is preferred.

Benefits

  • Competitive salary and a comprehensive benefits package.
  • Opportunities for professional growth within Nebius.
  • Flexible working arrangements.
  • A dynamic and collaborative work environment that values initiative and innovation.
