Breast cancer is the most treatable cancer, yet it remains the leading cause of death by cancer in women—largely because national screening programs miss up to 1 in 3 cases. The problem is even worse for women with dense breasts, who make up 50% of the screening population and for whom mammography is less reliable. At The Blue Box, we've developed a urine-based breast cancer test with a sensitivity of 88.42%, outperforming mammography by 15% overall—and by 30% in women with dense breasts. We're launching clinical trials in 2025 and bringing our test to gynecology clinics by 2026.
We are looking for an Electronic Engineer to join our dynamic team and spearhead the technical aspects of our breast cancer diagnostic device development. The ideal candidate will possess a strong technical background and a passion for driving innovation in healthcare.
We are currently seeking an Electronic Engineer to lead the development of our core sensing unit (e-nose) and embedded systems. This is an opportunity to make a tangible impact on women’s health and, if desired, pursue an Industrial PhD with us in collaboration with a local university.
