As a Technical Lead, you’ll work directly with the founder to shape the technical vision and execution of a high-growth startup backed by a larger, established group. You’ll lead a talented engineering squad, drive architectural decisions, and deliver scalable backend systems that support thousands of users-all while influencing the strategic direction of the product.
