We’re at a defining inflection point. With proven product-market fit and strong, global market pull, 9fin is accelerating toward becoming the category-defining platform for debt markets worldwide.
The OpportunityWe are seeking an Engineering Lead with proven experience to help scale our platform, set technical direction, and build a high-performing team that delivers meaningful product experiences. You will be at the center of how we make complex data accessible, reliable, and impactful, guiding engineers to solve high-value challenges across data, product, and infrastructure.

Coach and develop senior engineers, enabling them to take ownership of technical initiatives and expand their influence across the organization.
Maintain a deep understanding of system architecture, performance, and reliability to guide long-term investment in stability and scalability.
Hire, onboard, and support exceptional engineering talent. Dedicate time to one-on-one conversations to understand motivations, build trust, and strengthen team dynamics.
