## Description

We are looking for a Staff 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.

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

Requirements:

- 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

Benefits & Perks:

- Competitive compensation

- Career growth and learning opportunities

- Flexibility and ownership

- Collaborative and innovative culture

- Opportunity to work on impactful AI projects

- International environment and talented teams
