The Position

A healthier future. It's what drives us to innovate. To continuously advance science and ensure everyone has access to the healthcare they need today and for generations to come. Creating a world where we all have more time with the people we love. That's what makes us Roche.

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.

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

You develop solutions for Hardware-in-the-Loop testing for end-to-end testing of embedded instrument software.

You author and confirm correctness of requirements-driven tests, covering aspects including:

• Testing approaches (exploratory, white box, black box, etc.)
• Testing level (end-to-end, system, integration, unit, etc.)
• Testing types (functional, performance, scalability, etc.)

You automate and execute front-end and back-end tests, covering for:

• Instrument software
• Web applications

You automate deployment and testing pipelines across branches and stages.

You report quality metrics and enhancing quality dashboards.

You perform root cause analysis of defects and discoveries.

You develop automation frameworks and validate automation toolchains.

You ensure regulatory compliance of quality engineering deliverables.

You partner with Test Architects, Test Leads, and Verification & Validation Leads on practices.
