Join Roche, where every voice matters.

At Roche, we are working to make next-generation sequencing simple and accessible enough for routine use. By accelerating clinical research, streamlining workflows, and expanding assay menus, we are broadening access to genomic data and lowering barriers to adoption. From robust sample isolation and preparation tools to novel sequencing technology and advanced bioinformatics, we are developing differentiated, highly integrated end-to-end solutions for next-generation sequencing, resulting in a sample-in, result-out workflow.

You will design, fabricate, and assemble custom devices, fixtures, and breadboards using CNC machining, laser cutting, 3D printing, and advanced shop tools.

You will develop and implement microfabrication processes, including photolithography, etching, drilling, bonding, and dicing - and utilize precision metrology instruments to characterize components and evaluate manufacturing methodologies.

You will test, characterize, and troubleshoot complex fluidic systems and devices. Develop new workflows, protocols, and assays, while collecting, analyzing, and interpreting data to drive technical progress.

You will generate comprehensive test plans, experimental protocols, and technical reports to document findings and methodology.

You will operate, repair, and maintain lab equipment and custom instrumentation, ensuring optimal performance of breadboards and fixtures.

You will partner with a small, agile team of scientists and engineers, as well as the broader organization, to advance next-generation sequencing and diagnostic workflows.
