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, Web Socket, and proprietary protocols.
- Latency profiling, benchmarking, and continuous performance improvement.
- 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 Web Socket connectivity in production.
- Strong understanding of distributed systems and state synchronization.
- Preferred
- Trad Fi 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
- Person Profile
- Curious and autonomous
- Highly motivated and results-driven
- Strong maths and analytical skills
- Ability to successfully manage multiple tasks in a fast-paced collaborative environment
- Professional proficiency in English
- Company Culture & Values
- Take Action & Own the Mission
- Be of Service & Contribute
- Innovate, Create Value, & Be Courageous
- Act with Integrity & Respect
- Recruitment Process
Our process is consistent across all engineering roles and is designed to assess genuine technical depth. Candidates should expect the following stages:
- Stage 1: First round interview with a member of our Talent Acquisition team (45 mins)
- Stage 2: Binance take‑home assignment, AI-assisted + online technical screen AI‑free.
- Stage 3: 30‑45 mins with CTO - assessment of system design, technical experience, discussion of AI output.
- Stage 4: Online Coder Pad interview with HFT team - Rust focused.
- Stage 5: In‑person technical interview covering live‑coding, data‑structure & algorithms round, and background and goals alignment.
- Stage 6: Round‑Up meeting with Head of Talent Strategy.
- International environment (English is the main language)
- 100% health coverage
- Team events and offsites
- Company Pension scheme
