About the role

Staff Software Engineer focused on the indexing and data processing layer of a novel agentic search engine. Build and optimize large-scale offline/nearline data pipelines to ingest, process, and organize massive data volumes for fast, reliable retrieval by AI agents.

Responsibilities

  • 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

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, etc.)
  • 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
