Résumé du poste

Nebius Group is building a new era in cloud infrastructure for the global AI economy. We’re hiring a Staff Software Engineer to advance the indexing and data processing layer of a novel search engine designed for agentic AI consumption.

You’ll shape offline/nearline pipelines, ensuring data freshness, scale, and correctness across tens of gigabytes per second and petabyte-scale datasets. You’ll design, implement, and operate core ingestion and processing systems, optimize storage formats, and

Qualifications

• 8+ years of experience building production backend or data infrastructure systems.
• Strong Go experience (C++/Rust is a plus).
• Experience with large-scale data processing systems (10+ GiB/sec throughput, petabyte-scale datasets).
• Experience building or operating databases, storage systems, data planes, or indexing pipelines.
• Strong understanding of distributed systems, fault tolerance, consistency, and scalability.
• Experience running production systems and handling operational incidents.
• Systems-thinking mindset and ability to reason about end-to-end data flows.

Responsabilités

• Design, implement, and operate large-scale indexing systems and data pipelines that sit at the core of our search infrastructure.
• Develop and optimise indexing strategies balancing performance, freshness, and resource efficiency.
• Work on storage formats, compaction strategies, and update mechanisms to keep data accessible and current.
• Ensure reliability and predictability of pipelines under high-throughput conditions.
• Build well-tested components with clear responsibilities and interaction contracts, while remaining flexible as the system evolves.
• Define and implement observability primitives, including structured logs, metrics, and data quality signals across offline and nearline pipelines.
• Monitor throughput, resource usage, and cost, and drive optimisations when business needs require it.
• Collaborate with runtime and ML teams to ensure indexing outputs meet retrieval and ranking requirements.
• Enable safe experimentation on indexing strategies and data processing logic through controlled rollouts and clearly defined quality signals.
