Our Verification and Validation team, a part of Roche Sequencing Solutions, is responsible for ensuring a software product meets its specified requirements and performs as intended by rigorously testing and analyzing the software throughout its development lifecycle. 

As a Principal Software Developer in Test, you will be responsible for test design, development, automation, deployment, execution, and reporting. Specifically, you will develop an integrated hardware-software framework for end-to-end test automation that leverages a third-party Hardware-in-the-Loop solution. In this role, you will represent quality engineering and verification on behalf of your team in all events and activities related to this effort, working closely with software and hardware engineers across multiple global locations.

​The Opportunity:

Responsibilities

Work Environment and Role Expectations:

This role combines software testing responsibilities with hands-on interaction in a lab environment where our medical device systems are built, integrated, and verified. While many tasks—such as test planning, automation development, and documentation—are completed in an office setting, a significant portion of the work involves executing and troubleshooting software tests directly on physical hardware in a lab.

Candidates should be comfortable working around electromechanical systems, automated instruments. Lab work may include initiating test runs, collecting data from real devices, analyzing system behavior, and collaborating closely with software, hardware, systems, and manufacturing teams.

Relocation benefits are not being offered for this position.

The expected salary range for this position based on the primary location of California is $162,600 - $302,000.00. Actual pay will be determined based on experience, qualifications, geographic location, and other job-related factors permitted by law. A discretionary annual bonus may be available based on individual and Company performance. This position also qualifies for the benefits detailed at the link provided below.
