Lead the technical evolution of our core decision-making systems in a hands-on Senior Staff Engineer role that balances architectural design, people management, and shipping critical code. As the Senior Staff Engineer in the Repeats team, you will guide both the technical architecture and the engineers responsible for its delivery. You will lead the design and development of systems that intelligently route existing customers to the most appropriate credit assessment process and the most appropriate offer terms, based on their unique profile and needs. This means moving beyond static rules to build scalable, adaptive systems that integrate real-time data and business logic. You will manage the team's engineers, own the technical roadmap, and actively contribute to the codebase. You will be the direct line manager for three engineers, responsible for their performance, coaching, and career development.
