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
