️ About the role

We’re hiring a data engineer to build the ingestion and search systems behind Solve Intelligence’s AI products.

Our sources include global patent literature, case law, technical standards and contributions, scientific databases, academic papers, and content from across the web. The data spans structured records, documents, images, audio and video. You’ll work across bulk ingestion and on-demand retrieval, making this information searchable and useful in our products

You’ll own systems from source acquisition through to serving queries. The work includes:

• Large-scale ingestion. Build and operate high-throughput, resumable pipelines for large datasets, with efficient incremental updates, monitoring and recovery from failures.

• Document processing and data quality. Extract useful content from complex documents and other formats. Handle malformed records and changing schemas, and validate outputs while preserving structure and metadata.

• Search and serving. Build keyword, vector and structured search, and design schemas, indexes and partitioning for fast queries over tens to hundreds of millions of records.

• Connecting information across sources. Link patents, scientific records and supporting documents, preserve dates and versions, and make results traceable to their original sources.

• Performance engineering. Profile parsing, ingestion, database builds and queries throughout development, testing against representative datasets at realistic scale. Diagnose CPU, memory and storage I/O bottlenecks, and tune jobs and infrastructure for throughput, latency and cost.

You’ll work closely with our AI researchers and product engineers, with substantial freedom to choose the approach and build the systems yourself.

️ What you bring

Must haves:

• Strong Python and SQL, with experience designing and operating production databases.

• Solid experience building and operating production data pipelines over large, messy datasets.

• Expertise with running search systems over large document collections.

• End-to-end ownership from raw data to user-facing functionality.

• A good understanding of schema design, indexing and query optimisation.

• A track record of diagnosing and fixing performance bottlenecks in live systems through profiling and measurement.

Nice to Have:

• Experience with PostgreSQL/pgvector, OpenSearch (or Elasticsearch), Spark/Delta Lake, AWS, NoSQL databases, or Rust/C++ is useful.
