Founded in 2020, we have grown into a global team supporting institutions, exchanges, and token issuers worldwide as the financial system evolves toward tokenized markets.

Why join Flowdesk? You'll be joining a company operating at the intersection of finance, technology, and crypto - solving complex market problems, building critical infrastructure, and helping shape how digital assets move globally. We move fast, think long term, and work with a strong ownership mindset across engineering, trading, product, operations, and business teams.

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, feed handling, and strategy execution. The successful candidate will have direct experience building these systems in production and will be comfortable working at the systems level – networking, parsing, and latency optimisation.

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

Requirements
Must Have

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

Preferred

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

Location

London (primary preference)
Dubai (also open)
Remote: considered only for candidates with 1-2+ years at a recognised institutional trading firm
