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.
