React work that powers markets rather than another customer-facing product. You'll build the web and desktop applications traders and market operators use to run, monitor and control exchange infrastructure, technology this firm licenses out to other markets too. Ownership over ticket-shuffling, on a platform where unreliable code has a visible consequence.

Market microstructure research that actually ships into product. You'll join a specialist product group at one of the largest historical market data businesses in the industry, working across quantitative research, product development and client interaction, with direct access to exchange data environments most quant researchers never see. If you want your analysis to influence what gets built rather than sit in a notebook, this is the role.

Multiple senior C++ hires on the core platform powering electronic equities markets across Europe. You'll build event-driven, real-time systems that stay reliable under heavy throughput and respond in microseconds, working in modern C++ on Linux. Genuine freedom to shape architecture and challenge ideas, not just implement tickets.

Operations leadership hire to take a competent first-line support team and make it excellent at a listed European exchange. You'll own release coordination, shift scheduling, incident management, and client relationships with tier-one banks, with genuine autonomy from day one. This is about shaping how the function runs, not inheriting a ticket queue.

Full-cycle Account Executive for an AI content compliance company scaling in the US market. You'll own pipeline generation and complex B2B SaaS deals from prospecting to close, selling into legal, compliance and marketing teams across regulated industries. A genuine hunter-farmer seat owning a US territory with real headroom, $100k–$500k deal sizes against a $1.5M+ quota.
