Software Engineering

Founding Engineer – AI & Capital Markets Our client is an early-stage startup building an AI-native operating system for capital markets and trading. The goal is to rethink how trading organisations operate by addressing a long-standing gap in the market: modern, flexible software that truly supports front-office and trading-adjacent workflows. The company’s first product targets a high-impact middle-office problem—the reconciliation of exotic and complex trades. This is a painful, manual, and mission-critical process for trading firms today. From this wedge, the platform is designed to expand across the entire trading lifecycle, laying the groundwork for a category-defining system in capital markets. What you’ll do Architect and build the core platform from the ground up, making foundational decisions around scalability, data flows, and system design Design systems that ingest and reason over complex financial data, including market data feeds and trading systems, in an environment where requirements evolve quickly Take AI systems from concept to production, with responsibility for model serving, evaluation, monitoring, and reliability in enterprise settings Act as a true Founding Engineer, owning critical technical decisions and working closely with the founders in a low-bureaucracy, high-impact environment If you’re excited by capital markets and want to help define the future of how trading firms operate, this is a rare opportunity to build something foundational from day one.
