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 ### 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.
