Company: Quotient

Building on 30 years of experience in transfusion diagnostics, Quotient is committed to delivering solutions that reshape the way diagnostics is practiced.  Quotient has two key product portfolios, Alba by Quotient™ and MosaiQ™ by Quotient. The Alba by Quotient™ product range is comprised of high-quality reagents used to keep laboratories around the world running efficiently. They are sold directly to laboratories or through our OEM partners. MosaiQ™ by Quotient is our proprietary multiplex microarray technology, offering the world’s first fully automated, consolidated testing platform, allowing for multiple tests across different modalities. Quotient’s operations are based in Eysins, Switzerland, Edinburgh, Scotland and Chicago, Illinois.




Quotient is recruiting for a Mechanical Senior System Engineer to join the MosaiQ Engineering team. The role is a full-time and permanent position, based in Eysins, Switzerland.




The Senior Systems Engineer will be working within the system R&D function on the MosaiQ instrument platform. The MosaiQ instrument platform is a multimodal, multiplex microarray system has been designed to design a broad spectrum of applications in the field of transfusion and clinical diagnostics.

The candidate will be presented with the unique opportunity to lead the continued evolution of the platform with duties including development of new technology concepts and implementation into the system, leading the reliability growth plan for the MosaiQ system as well as supporting Assay integration into the system.



The Senior Systems Engineer will be responsible for identification of technology, development for integration into the Mosaiq system to improve the analytical performance of the system.

The candidate will lead the reliability growth plan for the instrument, performing pareto analysis of failure modes and driving the evolution of system both best in class MTBF, MTBI system performance.

Activities include characterization or root causing of instrument in consultation with assay R&D development team, enabling the completion of projects to the agreed timelines and the highest possible standard.

The candidate will also be assisting in planning, organisation, and execution of experimental studies, in the R&D department of Quotient.

The successful candidate will be part of dynamic team that drives innovation, leads or collaborates on key scientific and technical initiatives, and will be a key contributor to global launches of novel clinical in vitro diagnostic applications on the MosaiQ platform.
