Lead Software Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Lead Software Engineer based in United States. Provide senior technical leadership for a core Platform Services team responsible for APIs and services powering a broad software platform. This is a senior individual-contributor role focused on architecture, hands-on engineering, technical direction, and mentorship rather than people management. You will shape scalable, secure, and maintainable backend systems while leading complex cross-team technical initiatives from design through delivery. The role requires strong expertise in distributed systems, APIs, interoperability, cloud-based SaaS development, and modern engineering practices. You will partner closely with engineering leadership and other technical teams to translate strategic priorities into practical technical roadmaps. You will also help raise engineering standards through architecture reviews, code quality, mentoring, and thoughtful technical decision-making. This is an opportunity to make a broad technical impact while remaining deeply involved in production engineering.
