Job Description

Software Engineer - Infrastructure & Systems
London | 120k-150k + Equity | On-site (5 days/week)
We're working with a stealthy but seriously impressive startup that's rebuilding the data warehouse from the ground up--designed for complex, multimodal data like time-series, geospatial, point clouds, genomics, video, and more.
This is a rare opportunity to join a small, world-class engineering team (ex-Palantir, Citadel) at the early stages of a deep-tech journey. They've secured significant backing, have a 7+ year runway, and are tackling bold infrastructure problems that blend cutting-edge open source with proprietary cloud architecture.
They're now hiring a systems-focused engineer to help build out the core storage engine and distributed infrastructure.
The work spans:

• Building high-performance, low-level systems in Rust
• Designing distributed cloud-native infrastructure
• Optimising file formats and compression strategies
• Shaping query execution performance
• Preparing the platform for real-world customers

What they're looking for:

• Strong systems engineering background
• Experience with performance-critical software (Rust, C++, or similar)
• Interest in distributed systems, database internals, or storage engines
• Product sense: you care about how infrastructure gets used
• Bonus if you've worked with tech like Apache Arrow, Parquet, DataFusion, Clickhouse, DuckDB

What's on offer:

• 120k-150k base + meaningful equity
• Full-time, on-site in Shoreditch (Monday-Friday)
• A chance to do foundational work with real long-term impact
• Visa sponsorship available
