Job Description:

Are you a Rust/C/C++ programmer looking for the next best role?
Have you worked with low-level performance and want it to matter at a large scale?
If this sounds like you, this might be one of the most technically ambitious roles you’ll come across.
We’re partnering with our client who are developing a multimodal data warehouse that unifies storage and querying for highly complex domains — including genomics, financial & time series data, weather, and much more.
They are looking for a Senior Software Engineer to join their team in London on a full-time basis.

What You’ll Do

• Architect and implement high-performance data processing systems in Rust
• Leverage Apache Arrow and Parquet for in-memory and on-disk data efficiency
• Integrate and extend systems like DataFusion, ClickHouse, and DuckDB
• Design low-latency pipelines for analytical workloads
• Collaborate with product and platform teams to expose these capabilities via modern APIs
• Contribute to open-source projects and shape the future of their internal engine

You’ll Be a Great Fit If You:

• Have experience with Rust/C/C++ or systems-level languages
• Experience with columnar formats like Arrow and Parquet
• Have worked with or contributed to analytical databases like ClickHouse, DuckDB, or DataFusion
• Understand memory management, file formats, and query execution pipelines
• Are passionate about open-source and care about software craftsmanship
• Thrive in a startup environment
