Senior Quality Supplier Engineer

About Zenflow
Zenflow, Inc. is a privately held medical device company dedicated to improving treatment for patients suffering from urinary obstruction caused by enlarged prostate. The innovative Spring® technology was designed with the patient experience in mind and relies on a small spring-like coil that gently props open the urethra, restoring its normal function while preserving the natural anatomy. The Zenflow Spring System is now FDA approved for commercial sale.

PURPOSE OF JOB: The Senior Quality Engineer is responsible for establishing, managing, and continuously improving the supplier quality program as the company commercializes its first product. While supplier quality is the core focus of this role, the Sr. QE is expected to contribute to the broader quality function as needed, including support for internal audits, CAPA, nonconformance management, and quality system improvements. This role ensures that all components, sub-assemblies, and materials sourced from external suppliers consistently meet Zenflow's quality, safety, and regulatory requirements. The Sr. QE works cross-functionally with R&D, Manufacturing Operations, and Regulatory to qualify new suppliers, manage supplier performance, and drive resolution of supply chain quality issues. This role is expected to operate with a high degree of independence and ownership, helping to build scalable supplier quality systems that will support Zenflow's next-generation product pipeline.
