Staff / Senior Software Engineer (Agentic Search) - Index

We are looking for a Senior Software Engineer to work on the indexing and data processing layer of a novel search engine tailored for agentic AI consumption.

In this role, you will focus on building systems that ingest, process, and organise massive volumes of data into efficient, queryable structures. You will work primarily on offline and nearline pipelines, ensuring that data is fresh, complete, and efficiently accessible by downstream retrieval systems. You will operate in an environment where throughput, scalability, and correctness are critical; designing systems capable of handling tens of gigabytes per second across continuously evolving datasets.

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
