Principal Software Developer – BloodTrack Tx (C++ expert)

Haemonetics•Boston, MA

15d•$103,600 - $176,400

About The Position

We are seeking a Principal Software Developer to lead the technical strategy behind BloodTrack Tx®, our point-of-care transfusion management solution that electronically verifies patient identification from sample collection through bedside transfusion administration. This is a uniquely complex and multi-surface engineering challenge: BloodTrack Tx spans embedded workstation software, native mobile applications, and cloud-connected backend services — all operating in high-stakes clinical environments where a missed verification or dropped event can directly impact patient safety. You will set the engineering vision across this full stack, driving architectural decisions that ensure the right blood reaches the right patient with ironclad reliability, whether a nurse is scanning a wristband at the bedside on a mobile device or a blood bank technician is managing unit dispensing from a workstation. As a principal-level contributor, you will apply deep expertise across C++, iOS, Android, .NET, and TypeScript/JavaScript to unify a multi-platform product surface under coherent architectural principles — leveraging event-driven design to propagate transfusion events in real time, service-oriented architecture to integrate cleanly with SafeTrace Tx® and hospital information systems. You will own the architecture strategy underpinning BloodTrack Tx's scalability and security, mentor engineers across platform disciplines, and collaborate with regulatory and clinical stakeholders to meet regulatory and compliance requirements. If you thrive at the intersection of embedded systems, mobile engineering, and distributed architecture — this is a rare opportunity to shape both the technology and the team at Haemonetics.
