You’ll be a key contributor in a high-ownership, cross-functional environment, working closely with product managers, designers, compliance, and other engineers. From authoring transaction workflows to implementing scalable event-driven services, your work will shape the core infrastructure used by clients, partners, and developers globally. This role is ideal for engineers who enjoy solving real-world financial problems at scale, care deeply about system correctness and resiliency, and thrive in fast-moving, collaborative teams.
