About Flowdesk



At Flowdesk, we are building the infrastructure powering the next era of global finance. As a full-service digital asset trading and technology firm, we provide liquidity solutions, OTC trading, and market infrastructure that connect digital assets to global markets with institutional-grade precision, transparency, and scale. Flowdesk combines expertise from traditional finance, algorithmic trading, and blockchain technology to deliver always-on trading capabilities across the digital asset ecosystem.



Founded in 2020, we are a global team supporting institutions, exchanges, and token issuers to enable a tokenized financial markets ecosystem.



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 connect to global liquidity. We move fast, think long term, and work with a strong ownership mindset across engineering, trading, product, operations, and business teams.




Role Description



This is a search for a senior engineer who can lead our exchange connectivity capability end-to-end. The role requires a rigorous operational approach to quality delivery, combined with deep technical and trading expertise. The role requires the ability to lead, make architectural decisions, manage go-live cycles, and debug complex production issues across a broad set of venues. We are looking for an AI-forward developer in this role, who understands the value of building repeatable AI coding workflows to maximise engineering productivity.




Key Responsibilities

• Owning the design, build, and operation of feed handlers across all connected venues.


• Leading connectivity go-lives: planning, staging, testing, cutover, and post-launch support.


• Debugging complex production connectivity issues across exchange protocols and internal systems.


• Setting technical standards for how the team approaches exchange integration.


• Mentoring engineers working on connectivity components.


• Contributing to HFT infrastructure where connectivity and execution overlap.

Requirements


Must have

• Extensive crypto feed handler experience across multiple venues in production at an institutional firm - not experimental or internal-only.


• Deep understanding of market data feed handling, order lifecycle management, and multi-feed aggregation.


• Minimum of 2+ years of solid technical Rust experience, across sync and async code. Demonstrable experience of low-latency Rust development, at the very least 5+ years of C++ experience in a low latency environment.


• Strong understanding of networking protocols down the stack: HTTP, WS, TCP/IP


• Understanding of the full go-live cycle: from integration and UAT through to production cutover and ongoing support.


• Proven experience leading multiple venue migrations end-to-end, from cutover planning and parallel-run testing through to full decommission of legacy connectivity, including managing rollback procedures and minimising trading disruption during transition.


• Experience managing exchange-driven changes (EDC), upgrade lifecycles, and rapid go-live pressures.


• Experience with AI-first development workflows and AI harness engineering and quality assurance.


• Some leadership experience: technical lead, team lead, or similar. This person needs to be able to set direction, not just execute.

Preferred

• AI-native experience and AI harness engineering - delivered AI code generation workflows in production.


• Experience managing a team or squad of connectivity engineers.


• Experience across both TradFi and crypto connectivity (FIX, ITCH, OUCH, WebSocket, proprietary).


• Experience with ultra-low-latency development (kernel-bypass, zero-copy).

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
