Senior AI Rust Engineer (C#, Platform Migration)
We’re hiring a Senior Software Engineer for a globally active, multi-asset investment firm to build and scale a high-throughput, performance-critical trade management platform.
You’ll join a core systems team running distributed, event-driven infrastructure processing hundreds of millions of events daily. Development is primarily in Rust, with continued work in C#/.NET as the platform is actively migrated. The team places a strong emphasis on production-grade, AI-assisted engineering.
What you’ll do
*Build low-latency, multithreaded Rust services at global scale
*Maintain and evolve existing C#/.NET services during the migration to Rust
*Architect and operate resilient, observable distributed systems
*Use AI coding agents to accelerate delivery, owning quality and correctness end-to-end
*Optimise latency, throughput, memory usage, and cloud cost
What we’re looking for
*5+ years’ experience in performance-sensitive production environments
*Strong, hands-on Rust experience in production (mandatory)
*Practical use of AI development tools beyond basic code completion
*Recent experience in C#/.NET
*Distributed systems, async/concurrency, and Cloud experience (ideally AWS)
Nice to have
*Exposure to financial systems or trading workflows

Feel free to apply for more information.
