[Hiring] HFT Quantitative Developer @Flowdesk

Role Description

Our technology team builds and maintains the low-latency trading infrastructure that powers our operations - from execution engines and exchange connectivity to risk and market data systems. We move fast, operate at scale, and expect our engineers to take direct ownership of production systems that impact live trading P&L.

We are looking for a hands-on Rust engineer to join our High-Frequency Trading team. This is a core technical role focused on the components that sit closest to the market:

• Order Management System (OMS) development and maintenance
• Feed handler design and optimisation - processing market data at high throughput
• Strategy logic implementation and integration with execution infrastructure
• Low-level networking code: custom protocol parsing, socket management, kernel bypass techniques
• Fast parsing pipelines for market data and order flow
• Exchange connectivity across FIX, WebSocket, and proprietary protocols
• Latency profiling, benchmarking, and continuous performance improvement

Qualifications

• Direct, hands-on experience building OMS, feed handlers, and/or strategy logic in a production environment
• Strong Rust - the primary language for this role. Experience with both async and non-async (synchronous / bare-metal) Rust is highly valued
• Low-level networking: socket programming, protocol implementation, latency-aware design
• Experience writing fast parsing code - binary protocols, custom formats, minimal-copy pipelines
• FIX protocol and WebSocket connectivity in production
• Strong understanding of distributed systems and state synchronization

Requirements

• TradFi or institutional crypto market-making background (Preferred)
• Experience with kernel bypass networking (DPDK, RDMA, or similar) (Preferred)
• Familiarity with lock-free data structures and wait-free concurrency (Preferred)
• Options or derivatives experience (Preferred)
• C++ background - useful where Rust experience is being built (Preferred)

Benefits

• International environment (English is the main language)
• 100% health coverage
• Team events and offsites
• Company Pension scheme
• Learning and Development budget

Company Culture & Values

• Take Action & Own the Mission
• Be of Service & Contribute
• Innovate, Create Value, & Be Courageous
